Polar Vantage M Accuracy | Polar Vantage Accuracy V

Here we look at the most important aspects of the accuracy of the Polar Vantage M and the Polar Vantage V. Specifically we look at the performance of the Precision Prime optical HR and of the Sony GPS chip used by both Vantage models across different types of workouts in running, cycling and swimming; although other aspects of accuracy like steps, elevation and sleep are also at least briefly covered.

This post specifically forms part of the main and detailed review of the Polar Vantage, it’s included as a separate post to aid the reading of the LONG main review.

A couple of runs?

I’ve endeavoured to give both Vantage models extensive ‘testing’ since early September and I will probably update the charts in this post as I gather yet more data based on the live firmware. My intention is to see if I can switch to the Vantage next year so I should hopefully have more to add charts below as time passes.

Some of October’s ‘tests’ are shown in the image to the right and I’m sure there are duplicates in there from both watches and from the OH1.

Polar Vantage Accuracy

Elevation Accuracy

The elevation accuracy is cool. No issues here.

For once I managed to put a device to test with some relatively serious vertical meterage.

Each of these charts has one elevation plot which shows the ‘correct’ elevation based on a SRTM database. However, there could be some errors with that ‘correct’ track as mountainous regions can cause issues with SRTM-based elevation plots. Having said that, everything looked great with elevation more than a month before the launch of the Vantage.

GNSS: GPS+GLONASS Accuracy

Just like some cyclists will get very upset with a power meter that is only 98.5% accurate (rather than 99%) then some runners will get upset by inaccurate GNSS (GPS) tracks. Not because the tracks don’t look pretty after the workout but rather because the GPS signal has been used to show pace/distance continuously throughout the run. There are a LOT more runners concerned about pace and distance than there will ever be cyclists who care about power accuracy. FWIW: I care about both!

Test Route

I follow a formal methodology for at least one GPS test for each device but OBVIOUSLY then combine that with a view of how the device has performed over a variety of real-world scenarios in MY own training. One interesting finding is that almost ALL GPS sports watches are within +/- 1% accuracy of the median TOTAL DISTANCE value for my formal test. Which I think is pretty good and certainly NOT what I originally expected. Methodology, results and source files – here.

So if you are running a 26.2mile course then you might expect to be up to 0.262 miles out. Let’s say 400m for the sake of argument. Which will be a couple of minutes for many people. Yet this does not translate to some of the GPS horror stories you hear. One reason could be that buildings on city-based courses will disproportionately affect the pace/distance readings. ie a fully urban marathon route would probably have a MUCH larger error than +/-1%

But also lots of +0.5% and -0.5% errors could well cancel each other out. Not a problem for those of you wanting the correct overall distance (hmmm) BUT that is a problem for those of us wanting actionable instant pace. The segments on my GPS test were specifically chosen with those repeatable, ‘real world’ conditions in mind. >>>>>>>>>>Methodology, results and source files – here<<<<<<<<<<.

If you want a pretty, post-workout plot of your workout’s route then most devices are going to be fine for that. The Vantage is perfectly fine for that now.

Generally, I’d say ‘use a footpod’ if you want accurate instant pace and distance. However, some of the better, historic Polar and Suunto devices often gave GOOD instant pace from GPS.

Polar’s Vantage is making use of a new power-friendly GPS chip from Sony. Although I’ve spent many 10s of hours with the Vantages, all of that INITIALLY was with beta hardware and /or beta firmware. During the beta stages the GPS performance continually improved – I would certainly say that accuracy can still be further improved (as of 6Nov18). Then again, I would say that Garmin and Suunto can certainly improve their GPS accuracy too.

Bike

GPS accuracy when cycling is usually relatively easy. There are no arm movements and a relatively rapid speed helps smooth out the lines and bends. Also don’t forget that roads are more likely to be further away from trees and buildings which cause runners GPS reception problems.

The Vantage is perfectly fine for how I use GPS when cycling. Others may want a tad better performance.

Here are some examples

On a sweet 90k ride the Vantage performed well, although there were exception and this is a case in point (green) where it cuts one corner along with the Hammerhead. The Garmin 935 did that section fine but in the previous section the Garmin wasn’t on the road. So all was fine enough.

In the mountains (September on beta), again, things were generally quite good in often difficult GPS conditions. At a high level all is fine and dandy

Drill down to the switchbacks on the left (yellow = Vantage) and there are deviations (early beta hardware and software)

But here’s a much more recent example where all was not fine. Over a 3 lap course the Vantage, blue, has 2 perfect laps and then for no apparent reason does not want to play ball on the third lap (final hardware, final software). Strange

Here we have Box Hill with the Karoo (yellow) and the 935 (green, stem mounted) and the Vantage has the best track.

Around the next bend the Vantage M is fine but the Garmin is slightly better.

Here are multiple, anticlockwise passes of a roundabout from the 2012 Olympic Road route – albeit the roundabout was removed for the race (someone still managed to crash). I’m not sure that any of these tracks are particularly wonderful but they are all ‘alright’.

935 (Green), Karoo (pink), Elemnt (orange), Vantage (red)

 

Run

I am faced with somewhat of a quandary here. In a nutshell the Vantage M is of a similar, acceptably good standard as the Garmin 935. But the Vantage V really is NOT good. The Vantage M needs to be improved a bit to get the heady heights of the V800, the Vantage V needs MORE work. And that’s strange as I assume that both have the same algorithms and same chip. Perhaps the slightly heavier Vantage V with a metal case has issues because of the metal construction or maybe I have a partly faulty watch?

So I’m just going to give a few images for the V as I hope to be able to report back in the near future as improvements are made.

This is a very tricky section that involves a 270degree loop next to a high building, under trees and then under a bridge. Both V &M generally handle this well – in fact better than most other devices. But then there is a strange tooth-like jagged deviation from the route in the centre of the image, before recovering, by the V (red). Remember, I’m showing that as being indicative of behaviour elsewhere.

M=Green, V=Red

Here’s a typical run where the Vantage M does a very respectable suburban job. The track is not perfect but it IS GOOD (better than most) and within 5m of where I actually was – that is accurate enough if we apply sensible limits. The Vantage V (red) is out by 10m-15m in some places, which is not good.

Green=M, Red=V, Blue=935 (in back pocket #excused)

I had a bit of a fail on this run and only managed to get two devices to work. The M in red looks fairly accurate under trees (but I can’t prove it…grrrr) and the V (blue) is not accurate.

Here is a bit of a tree cover test in Bushy Park. The M (green) is very good and the 935 (red) is nearly as good but there is also the V (blue) running its own merry dance.

So. There is no point in talking about the Vantage V anymore. I’ll say that the images above are typical.

Here both the Vantage M and COROS Pace are each having a good day with quite a lot of tree cover along the riverbanks which often confuses a naive, young watch. Not the Vantage M, Nice Job.

Rotated image, COROS Pace vs Vantage M (Red)

Sometimes open skies can be harder than you’d think and here is a long, easy curving section where the COROS Pace and Vantage M do well. I sometimes get perfection here (eg V800 IIRC) but neither the COROS nor Vantage are perfect today. Actually these long sections are quite interesting as they often catch out devices which, for some inexplicably random one-off reason, run parallel to the track either North-South or East-West, or even a combination of both. I was once told this could be due to tiny timing errors on the watch. Maybe.

Vantage M (Red), COROS Pace (Blue)

Against the Garmin 935, the Vantage M performs with equal gusto for much of a 10k run in Bushy Park. The M was marginally more correct on this section and less correct later on.

Vantage M (Blue), 935 (Red)

Let’s try to switch to the Garmin 935’s super new GPS+Galileo precision. Here it is in red. The Vantage M (blue) is where I actually ran (near enough)!!!

Vantage (blue) 935 (red, + Galileo)

Although to be fair to the Garmin it was a bit better than the M a couple of KMs earlier

Vantage (blue) 935 (red, + Galileo)

But later when both are running close to houses and shops…surprise, surprise they are both rubbish; that’s GNSSS baby….it doesn’t play nicely with shops.

Vantage (blue) 935 (red, + Galileo)

I thought I’d try 935+Galileo (blue) again, but this time throw in the V800 (red). The Garmin is probably nearest to the real track on the whole on this section which might surprise some of you (and me!).

935+Galileo (blue), V800 (red), Vantage M (green)

Further on, in the same run, but in much easier reception conditions we get the following where they are all good enough with the Vantage going awry right near the top of the image (maybe trees).

935+Galileo (blue), V800 (red), Vantage M (green)

Again, below, Galileo on the Garmin and this time the same Sony Chip on the Suunto 9 (Best GPS). This was a 9-mile run and each device was good at different points, overall a very mixed bag. You can see the Vantage (yellow, left) just starting to go off track as I ran towards the next section where it wasn’t great. Although the Vantage M later became great for a long stretch on a tree-covered riverbank. Overall they were effectively ‘the same’ – of specific note here (based on this one run alone) the Suunto 9 after all these months with the Sony chips does not seem to have improved to the heady heights of GPS awesomeness that some of the SPARTANs achieved.

Suunto 9 (Red), Garmin 935 Galileo (Green), Vantage M (Yellow)

‘Hopefully’ that has created a somewhat confusing picture and given some food for thought. I say ‘hopefully’ because the true situation IS somewhat confusing. My overall judgement would be that the Vantage M is in line with the 935’s overall performance and effectively as good as the 935 in GPS-only mode – from experience, the 935 is consistently worse with Glonass or Galileo enabled.

I never compared like-with-like modes ie 935+GLONASS with the Vantage M (GLONASS always on) – If I did, I am positive that the Vantage M would be better. My time is too precious to waste.

I try to compare like-with-like in the sense of best ie ‘best 935 mode’ with ‘best Vantage mode’

Take out: Effectively the Vantage M is the same as the 935 for running GPS performance

Running Pace & Distance Accuracy

Running Pace comes from GNSS/GPS accuracy and has smoothing based on wrist movements. Running at constant speeds in good reception conditions, simultaneously with both Vantage watches, gave quite inconsistent ‘instant’ pace readings – sometimes the watches were out by 40 secs/km from each other, though more likely 30 secs/km from the actual pace by the worst offender at any one time.

Over longer periods, such as KM laps, the consistency of average KM pace for both watches naturally improved with the M being generally better.

Over more than 10 miles the V was still 99% accurate in recording the total distance. Compare this to 99.87% for the M. Such distance errors seem OK but 99% or less in my tests usually means that there are other issues with pace and distance recording on devices that score so ‘low’.

Take Out: As I said, the 99% distance accuracy hides numerous, smaller-scale, over- and under-estimations. The instant pace of the Vantages are not usable. You would need to use a footpod. This is NOT unusual and I would say a similar thing about every Garmin I’ve used. A 20-30 sec/km pace variation from the ‘correct’ pace is not unusual IMO.

OWS

Sorry it’s winter. These are tracks from other reviewers. Please come back in Spring 2019 (hmmm !!)

This track is from @trinakan

Source: nakan.ch, blue=reference, green=Vantage, red=Fenix 5X

and another from @dcrainmakerblog

Clciks to Youtube Source of dcraimaker, Yellow=reference, Red=Vantage, Green=AppleWatch4

Both look good enough for me. For OWS but it would be nice if the tracks were a bit ‘prettier’ (smoothed).

NB: Polar state GNSS Accuracy as Distance ±2%, speed ±2 km/h

oHR Accuracy

Better oHR accuracy seems to be obtained by wearing the watch tightly, notably in swimming. as the weather turned colder in the autumn/fall I found that keeping my wrists warmer improved readings too. Fiddling with the watch by moving it away from the skin during a workout seems to confuse the Vantage for several minutes afterward – don’t do that 😉

Whilst many more runners train by PACE than there are cyclists who train by power, I suspect that there are EVEN more casual runners who train by heart rate. Many of them will probably have absolutely no idea that their current wrist-based optical HR is wrong a lot of the time. Polar is aiming to produce the most accurate optical HR readings of any device. Do they?

I’ve included some of my older beta results that were good as these show what Precision PRIME is obviously capable of. I’ve only included current results that need to be brought to your attention.

 

June 2019 Update

This first section shows some updated results that look MUCH better than those from launch (further below). They are from the TITAN but Polar have assured me that the innards of a new Vantage V Titan are the same as the innards of an original Vantage V.

Running – Steady State

Sometimes both Vantage devices were able to produce near-perfect tracks for running over extended periods.

Like this

and also on the live firmware like this

Other times (late beta, below) the HR track was mostly perfect.

Running – Intervals

Once the watch was tightened after 15 minutes (!), a good track was delivered.

This has some harder efforts but was really a test for running power. Apart from the start both Vantage units are good (beta)

Switching over to the Vantage M, this was pretty cool. It’s the Garmin in red that is not playing ball.

Vantage is Green and is effectively spot on for oHR

Again on the M with some tempo paces – the red lines are the HRM-TRI (long story) and the Vantage M just underplays some of the efforts a little too much in places.

This hour run has some slightly harder efforts. The Vantage just over-eggs the HR a tad at the key moments towards the end.

These are longer intervals at a slightly higher intensity with a few dodgy moments for the Vantage V

I also found some less good results as the weather got colder. I think for me this reduces blood flow in my skinny wrists and hence oHR suffers. However this track was with arm warmers and is pretty cool (well…pretty warm ;-0 )

This was trying what felt like hard for 2×20 with arm warmers too. Even the Suunto 9 had arm warmers on the other wrist. Hmmm.

Here we see another generally good performance but we also see a few minutes of under-reporting of HR on the Vantage M, this happened several times.

 

My first ‘conclusion’ a few weeks back was that the lighter-weight Vantage M seemed slightly better for running than the Vantage V. Maybe I wanted it to be? Over all my runs, in reality, they are probably equal; even if, on one day whilst wearing a watch on either arm, I might find that either one could be better.

I would also say that the Precision Prime technology can clearly be excellent. I suspect that by getting a tight fit before setting off and keeping warm I would have even better results from both Vantage devices.

Cycling – Long Ride

On good surfaces we can get apparently great results over extended periods

yep. Same again over several hours

and again. Several more hours.

This time it was even better than a chest strap which had 2 hours of madness and then started working again.

There were a few unexpected troughs on this lapped ride at a slightly higher level of exertion and on a slightly bumpier road than those above.

This is more dubious. But ‘great’ for extended periods despite the occasional dubiousity

Not bad at all

Awesome on a turbo trainer doing intervals/ramp (as expected)

And again, although not as intense, with the Vantage M

This one on a turbo is not so awesome (beta FW) but I was fiddling around quite a bit with another sensor (Hex) and had my wrist quite bent (not my usual cycling position!). I only include it to give a ‘full picture’.

But wait a minute. Let’s look again at the Vantage M. It is a lighter weight device and this might mean the M moves about LESS on the wrist and MIGHT give a better oHR reading as a result.

This certainly looks good for a relatively easy Z2-Z3 bike effort. Even the HRavg figures are the same as with the HRM-TRI. This is the SAME BUMPY route as a few of the other Vantage V results (above) that were not quite so good. Having said that, the one below IS the M on retail firmware.

There are some differences with the V & M compared to chest straps, as shown above. I tend to get BAD oHR results from cycling on mildly bumpy tarmac  – or worse. Results in better conditions like a turbo or smooth roads can improve performance notably. These (and other) results from the Vantages are probably better than any previous oHR device I have tested whilst cycling. I’m still going to use a chest strap though!

Swimming – Pool

Hey…25 minutes. Tighten up that strap will ya? I did and all was much improved.

Next time maybe START with a tight strap and look what you get. This is me trying fairly hard in the pool after 25 minutes or so of faffing around with drills. Actually I’d say this was good for a swim oHR track…certainly better than Garmin’s oHR in the water (they don’t do it 😉 )

Here I used paddles for the whole 30 minutes…don’t do that.

 

This one is not quite as good as the earlier ones but still alright for a swim track.

With those 3 tracks I thought I had resolved what I needed to do.

But then I got this in a steady-state 40 minutes in the pool. No paddles, exact same conditions

Let’s leave on a positive note for pool swimming. You can reasonably expect this and this is alright for swimming oHR.

 

With Swimming oHR accuracy, Polar’s Vantage IS better than anything else. It’s still not really accurate enough for my liking but, perversely, I might use it as I REALLY don’t like wearing a strap in group pool sessions.

Free Weights

I have done some low-level weights over 4 sessions with the Vantages. The results were not good. I find that the same as every single other wrist-based oHR device. I never quite see the point of measuring HR when doing weights. Mine rarely goes over 100, although I can get it up to 130 if I do a silly number of squats with weights. Maybe I need to try harder?

Take Out: oHR Accuracy

Polar Vantage V Review, Polar Vantage M ReviewI take heart rate seriously in my training and I am going to be super-critical as a result.

These tracks are some of the best I’ve seen from a wrist-based oHR device. Precision Prime is probably on a par with Garmin’s ELEVATE but it’s still not quite good enough for me. I know this is still work-in-progress.

I’m going to keep my eye very firmly on these oHR tracks and MAYBE, just maybe, Polar will be the first company to get me to bin the chest strap in the near future?

If YOU really want a wrist-based oHR then I reckon that Polar Precision PRIME is one of the best available right now AND it should, hopefully, improve to boot. I can’t see Garmin’s current iteration of ELEVATE hardware being improved by software fixes. Garmin’s ELEVATE needs a redesign to further improve.

Caveat: optical HR varies from person-to-person. You may have better, or worse, experiences.

Running Power Accuracy

The accuracy of Polar’s running power needs to be the subject of proper 3rd party lab tests. And that statement applies to all the Running Power companies.

Polar’s Running Power *IS* perfectly usable, it’s just that all the 4 companies in this space do not agree with each other. Q: Which one is ‘correct’?…A: I’ve no idea. The only caveat I would add is that both Polar and Garmin base their running power algorithms partly on pace. When their source of pace is a GPS/GLONASS/GALILEO signal then you will get the same vagaries with power as you do with pace eg as caused by tunnels, buildings and tree cover.

If you want to look at lots of charts showing 4 companies’ running power that don’t agree with each other then click-through to the following linked post 😉

Polar Vantage V Power vs RunScribe Plus vs STRYD vs Garmin Running Power

I have EVEN more running power comparison charts than shown in the previous link. They ALL say the same thing. #DISAGREEMENT

My overall impression is that Polar Vantage V’s power calculation is a reasonable proxy of my effort. It is usable. Given the choice I would use either RunScribe or STRYD but I could see how many of you would not want to make that investment. In which case, give the Vantage V a go…you WILL get some benefits that help you augment how you currently run to HR/PACE/RPE.

TAKE OUT: Really. I mean really. Choose a specific way of getting running power and don’t change it. If you choose to go with the Vantage V’s internal calculations then ALWAYS stick to either a footpod or GPS+GLONASS as its source of pace. I love running with power. I’ve always used STRYD and that isn’t going to change. If you want to go for the Vantage V’s power algorithm then you will definitely get benefits from it in training/racing but STRYD or RunScribe will be more consistent (IMO) because of the variability of pace from GPS inherent in the Polar and Garmin solutions.

General Activity/Sleep Accuracy

Almost everyone buying a Vantage will be embarking on various athletic endeavours even if they might not be calling themselves an athlete. The general activity’ stuff ….steps…is not really that important. I’ve had a cursory look at steps and the like and it seems in the right ballpark for day-to-day comparisons.

Whilst I don’t look at calories I know many of you do. I have no way to professionally validate Polar’s calorie calculation. All I can say is that they have historically had the reputation for the BEST calorie estimation. Q: “Is the Vantage the best at correct calorie calculating?”…A: “I don’t know”.

Sleep tracking is one that we need to look more closely at. It is generally thought that your body adapts to your day’s exercise whilst sleeping. Poor sleep = poor adaptation. So sleep IS important. The problem is that even the ‘gold standard’ sleep lab machines are, apparently, not fully accurate.

Over a whole week (more than shown below) Polar IS getting my total hours in bed AND ASLEEP to be correct – at least to a good level.

Polar Vantage Review - Polar Flow

Weekly Sleep Overview

Looking at specific nights then Polar’s SLEEP PLUS seems to closely resemble my feeling of what my last night’s sleep was.

Polar Vantage Review - Polar Flow Dashboard

Look again at those charts more closely. Polar has, sensibly in my opinion, chosen to avoid guessing what the sleep stages are (N1, N2, N3, etc). I use the word ‘guess’ deliberately as I suspect that is kinda what most other brands are doing. Polar’s SLEEP PLUS looks to me to be an honest and competent reflection of how much sleep you’ve had and broadly how well you slept. Is it perfect?…no. Is it useful? … probably…a little bit.

Polar also take SLEEP one step further in Recovery Pro with the addition of mood & sleep feedback in their assessment of your readiness to train. That DEFINITELY adds a layer of proper usefulness.

55 thoughts on “Polar Vantage M Accuracy | Polar Vantage Accuracy V

    • i think the V will eventually become a pretty awesome tri watch. this accuracy (gps/ohr) is just one aspect of the package that affect people differently. eg me !! – I don’t mind that much care about the gps or ohr as i know i will end up using stryd+h10. the interesting take-out tho is that this MIGHT be the one ohr that can actually be generally accurate.

      • I actually do care about gps and heart rate accuracy. Up until now I was using a spartan trainer wrist HR and I developed a good relationship with it. I think the gps accuracy on the spartan and vantage m (that I got recently) is very similar. However Real time pace and distance feedback on the spartan is way way better. Maybe Suunto makes a better use of the accelerometer or doing a better job smoothing things out. At first a was really disappointed with the watch. Why would I change my spartan for vantage m? Apparently Vitality life insurance doesn’t synchronise with Suunto. It was between polar and Garmin 245 and I chose polar. I went for a few runs with both watches, Suunto have me a better feedback in real time. Now this vantage is growing on me, the whole ecosystem appeal to me, much better than Suunto in my opinion. My question is if you use a strap and foot pod what do you need the watch for?
        Also Why would you release a product and then develop a firmware for it? Then when it’s fully developed you release a new product and so on and on and on? Not sure I understand that approach.

        • lot of good questions there.
          they release the watch and then develop the features as they need cashflow. Everyone does that. it’s only a problem if there are inadequate features on launch
          strpa+footpod gives accuracy, the device records data and the device shows data and provides functionality. a sensor is just one of the inputs

  1. I was looking a few days ago on your xls with GPS results and didn’t quite understood how M can be different from V – now i see it clearly. Hopefully there is no major hw/design issue. The HR strap which failed for 2hrs – was it h10? Never saw anything like that on my h10 or h7 with v800…

  2. oHR, what color watch were you using for both the V & M? Was the ‘Prime’ sensor color matched to the watch or black? It seems many of the pre-prod units were black, even if the back plate of the watch was a different color.

    Given the experiences I’ve been having with the oHR–it’s been atrocious–I started poking around at this color thing. After quite a few responses from different places (DC Raimaker post, to facebook groups). Everyone that has a black watch generally likes the oHR results or have even compared it directly favorable to say a v800 + HR10.

    All results for those with non-black precision prime sensors–like mine being white–have been crap….

    Like I’m seeing a resistance by my ‘White’ Vantage V to ever want to go above 160bpm for steady state runs. I’ve have a smattering of direct-comparison data to V800 + HR10 & iPhone + Scosche Rhythm, it’s a huge discrepancy (not something lost in the noise/just missing peaks/failing where oHR typically struggles).

    Do you have access to the different colors? Care to see any of the data? I really think Polar made this change last minute expecting things not to be impacted…

      • Interesting! Is your M’s ‘Precision Prime’ part white or black? I’ve seen on Instagram a lot of them were black, up till shortly after these ended up in the wild.

        I’ve been trying to get in touch with Polar but I can’t reach them at all via any channel I’ve tried 🙁

  3. So it seems all these LEDs haven’t really done much for accuracy…At this point the conclusion has to be that WoHR is just not worth the effort or the aggravation when you can get an oHR band (the RunAR) for 25 EUR with MUCH better performance, and that’s if you really can’t stand chest straos 😉 Actually I found the RunAR to work better than the HRM-run in the summer on the track when the sweat confused it.

    • ha !! maybe
      10% off the runar here 😉 newrunninggear.com/?utm_source=tfkrunner&utm_medium=banner&utm_campaign=NRG%20TFK
      i actually have one. i have never really used it tho. apart from once about 6 months ago. it came with a platic cover over the LEDs which i didn’t realise for a while. the results were actually alright even with that plastic cover on!!!
      i came to the WoHR conclusion that you arrived at ages ago and was very sad 🙁 The MIO Link was pretty cool and pretty good and things just HAD to get better…but didn’t. but i am an optimist and hope for better things eg AW4. having said that the PRIME is very promising. i’ve seen some of the other stuff Polar are planning to do with it over the ocming months (post-processing…not a secret)…that looks cool and should help a tad more.
      it’s just that the wrist is SUCH a conveninet place to measure…albeit a rubbish place 😉

  4. Have you noticed any difference in the visibility of the screens given the different glass used? I find the V’s screen to be difficult to read even outside. I think it’s partly due to the lack-on-white text, and partly due to the thin fonts used. But I’m curious if the difference in glass comes into play also?

    • good question
      with the backlight on they are the same
      with it off the M is a tad clearer.
      my main issue is the thin text when i wake and do the ortho test,,,i cant read it without backlight

      • I was wondering specifically if the glass used on the V made the screen more difficult to see outside in the shade than the glass used on the M.

      • I have both in front of me right now, and it’s hard to say. I agree with the M being a little clearer, but the difference is minimal. Lighting conditions and the angle of the light source makes a bigger difference than V vs M.

        • Thanks, Fabian. How do you find readability outside while running? Inside under the lights the readability is fine, but I really struggle with it outside in less than full sun. It feels far less readable than a comparable Garmin to my eyes.

  5. Thank you. It is interesting that there is a difference between the M and V’s GPS performance. Have you heard anything from Polar on why this might be? What an irony that the old V800 still comes out best.

  6. So is there something that I don’t understand, in terms of the total distance there is no major difference between Vantages and 935, but when we compare the instant pace is where the polar watches present more problem, I’m correct?, maybe this can be corrected with a new firmware right?

    • total distance and total average speed will be directly related. total distance comprises the sum of smaller distances that can be over or understated or not…and hence over those smaller distances the instant pace will reflect inaccuracies in short term distance measurements.
      it can be improved with firmware.
      downtown city measurements could well have greater discrepencies

  7. Does live pace from the Stryd pod work / show on the Vantage? Never had much luck on the V800, and the difference is quite large when I have the Stryd synced to both Zwift and the V800 when running on the treadmill.

  8. Awesome post again! I see on my own M some good signs but definitly has to be more constantly accurate in gps and oHR.
    Other question. I just see the current actual pace but is there a ‘current avarage lap pace’ (I had on my G610). So am I still in my 4:00 min/km pace in the current km? Its more constant and so usefull than the actual pace.

  9. I’m looking to replace my old M400 with a new watch. It still works but it looks like the dog just ate it. Currently I’m on the fence between a Vantage M and a Spartan Sport. Currently the Vantage is about 50 USD cheaper where I live. The hardware of the Suunto looks slightly better, and I noticed that you score them really well on GPS accuracy. I always use a chest strap, so oHR does not really interest me. Would you say that the accuracy difference between the sport and the M is big – and worth the step up? The downside of Suunto seems their software platform and multiple apps, while the ecosystem of Polar is pretty solid and easy to use. Main uses would be frequent half marathons, an occasional marathon, cycling in summer, and sporadic pool swims.

    • hi
      yes your comments there are all correct, i’m not sure what suunto are doing with their apps/platform.
      check the exact Suunto model for gps accuracy as i found the Spartans varied. if it’s the SPORT non-WHR then that one is cool from my experience and more accurate.

  10. I run regularly on the same courses and I know where the mile markers are. I have the Polar v800, the Polar Vantage V, and the Garmin 737xt. The Garmin 737xt is a very poor performer dropping regularly 1/4 mile over a 7 mile run. Over the same course the Polar Vantage V behaves similarly. WIth respect to GPS distance accuracy the Polar Vantage V is no better than the Garmin 737xt or any other recent Garmin. They are all highly inaccurate and unreliable. On the other, hand the Polar v800 nails the mile markers on my courses with amazing consistency. It is by far the best running watch I have ever had. Comparing the Polar Vantage V to the Polar v800 by wearing both on the same runs and then looking at the course plots it is easy to see why the Polar Vantage V is inferior to the Polar v800 as the Vantage V frequently wanders off course while the v800 hugs the course nicely. If you are concerned about accurate distance measurements then you should get the v800. There is no other GPS watch with comparable accuracy. I also have a Stryd footpod which I have been using for a year now. While it is fairly consistent with mile markers it is always a bit long. Using the Stryd footpod will give distance results that are more accurate than any recent Garmin, more accurate than the Polar Vantage V, but a bit less accurate than the Polar v800.

  11. Nice review. Thanks for it.
    Maybe some of you can help? I had some issues with oHR of my new vantage V during my last two workouts when I made interval run (treadmill and outdoor). During WORK interval, when I have more than 170 (aprox.) bpm HR and my real HR should become higher, my V starting to show my HR decreased and shoving HR below 140 bpm (aprox.). During REST interval, HR is shown normally. When I started new WORK interval, HR is shown normally up to 170 bpm. After that, shown HR is below 140 bpm.
    My wrist strap was tighten enough.

    Thank you in advance

  12. Do you have some result when doing HIIT (bootcamp) between the OH1 and vintage? At this point i have polar m430. When i`m doing 5min burpee the heartrate stucks at 130.

    I would like to buy the vintage m for running, cycling and HIIT training.

      • I understand. Other product compare the vintage will be fine to if thats possible? That wil be great

        I have search the internet and i can only find review about running “heartrate” not other kind of sports like HIIT (Bootcamp)

        • your physiology and usage will affect accuracy.
          if there are lots of motion artefacts (twisting wrist movements and large impacts) then accuracy will be further, negatively affected

          my advice is to use a chest strap

  13. Hi. Thanks for the review. I have bought the two vantages and a Garmin fenix 5 to test which one I prefer.

    I love the polar apes so kind of want this to be the one I choose. Does anyone know if it’s possible to connect headphones to them so it gives me feedback? The quick user guides don’t give you much info.

  14. Just wanted to ask about your comment on weight lifting and the vantage m. Was the problem inaccuracy or more the fact you feel they aren’t necessary? Only reason I ask is that I want to get this tracker for some outdoor use but primarily indoor gym use. Cheers.

    • can you say what exactly you want to use it for eg indoor running machine, zumba class, weights/reps eg for hr collection or rep collection

      • Indoor bike, hr collection on weights and HIIT. My exercise routine is for fat loss but whilst trying to build muscle too if that helps.

        • it’s pretty pointless colelcting hr on weights? it will be too low i would have thought.
          indoor bike will be fine.
          hiit may be alright. i woudl use an armband like the Polar OH1,
          for fat loss i would suggest very extensive endurance training plus weights. HIIT will get you fitter quickly but you might get injured and HIIT is not the best way for you to get fat adapted. IMHO

  15. Observation regarding GPS and open water swimming with the M … it’s all over the place! Maybe I need to swim faster

    • ha
      no the manufacturer might have to crank up the gps reading frequency for one. possibly could be an issue if you are doing breast stroke and the watch is always underwater. or very very very slow crawl 😉
      plus look at garmin last year with the 935…was fine for ages…they updated the firmware …then complete pants….eventually fixed

  16. Does anyone know if the Vantage V has better GPS recently? (Compared to the Vantage M/Titan)

    Bought the Vantage V(waiting for it to arrive) but not sure if I want to send it back and just get a Garmin Fenix.

      • After the update instant pace from my zwift pod is off by some way. I always used to compare it with strava as it uses gps to calculate distance and pace. Since the update the automatic upload on strava is exactly the same as polar flow in terms of distance and pace. I deleted automatic upload on strava and uploaded a gpx file. The difference was 0.5km. That’s 8.2km versus 8.7km on strava from gps.
        Can I change it so it only uploads gpx file?
