You can buy it from HoloSport, where the code THE5KRUNNER gives 10% off, or from Amazon in the US, UK and Germany.

Does HoloSwim 3 Pro replace sighting in open water?

Accepted Answer

No. The GPS and compass give an extra directional reference, but you still need to lift your eyes to check buoys, other swimmers and conditions.

Question 5

How accurate is the GPS on HoloSwim 3 Pro?

Accepted Answer

In my test, the track was less accurate than Garmin Fenix 9 Pro and Apple Watch Ultra 4, with an average distance discrepancy of 17.8 metres from the other two devices. HoloSport has released a GPS accuracy update since that test.

Accepted Answer

HoloSport says there is no subscription.

Yes. HoloSwim 3 Pro is race legal under the same World Triathlon, USA Triathlon, British Triathlon and PTO supertri approval of smart goggles that FORM received in October 2023.

Question 8

Does HoloSwim 3 Pro work with Strava?

Accepted Answer

Yes. Completed workouts sync to Strava. HoloSport says you can also import a planned route from Strava, but I haven&#8217;t tested that.

Question 9

Does HoloSwim 3 Pro work with a Garmin or Apple Watch?

Accepted Answer

Yes. It transmits live data to your watch, where the HoloSport watch app or Connect IQ data field reads and records it.

Question 10

Which are the best smart swim goggles, HoloSwim 3 Pro or FORM?

Accepted Answer

HoloSwim 3 Pro has built-in GPS, looks like normal goggles and has the larger display, so I prefer it for open water. FORM Smart Swim 2 has the stronger app ecosystem, so it suits swimmers who want detailed structured plans.
