The 920XT now has swim workouts. They’re pretty good and can be added through Garmin Connect. You can even include sets with paddles/snorkel and paddles..Nice!
Some of you will like alerts – 50m to go, or something a little cleverer. I’m pretty happy with it as it is and just use it as a glorified lap counter – which is tricky sometimes as it counts distance and not laps.
Stick your 920XT on the cradle and get the 7.1 firmware. Wear your HRM-RUN/TRI and you’ll get the ‘special’ (ahem) running dynamics as well if you don’t already have them.
Also check out the LINE watch face. Looks good. I’ve finally found a watch face I like. Shown here on the right on the quite nice and new Garmin Forerunner 735XT (nice but no need to upgrade form your 920XT).
Here’s a quick image of one of the screen on CONNECT where you can create a swim workout.
