OPEN WATER DISTANCE ISSUES

Hi there,

8 out of 10 times the open water tracking is way off. Even in relatively short swims (1200m) it records 15-20% less meters than others with who I swim. I also know the distance where I swim pretty well as I've been swimming there for many years.

It's pretty disappointing as I have to share my data with a coach and it always shows I swim much slower than what I actually do.

I understand I can edit the meters on the Garmin Connect app but that's not the point after spending more than 500€ on a device.

I've seen other posts about this issue but they are all from many months ago.

HAS ANYONE BEEN ABLE TO FIX THIS ISSUE?

Thanks for your help

Anthony

No Anthony., no solution.

I find that if i swim a 220 meter triangular course 10 times it underestimates by 25% and the track is not a triangle! However straight line swimming for maybe 1km gives reasonable data when compared to my back in gps in a swim float. I have tried all the GPS options to see which is best but nothing works.

Same here. Garmin has sent me 3 new devices (Forerunner 945) by now and still same issues! I talked to a guy from the Garmin technical department and he told me that recording data in the open water is the most difficult task and to maybe put my watch on a buoy so it was above water at all times... not the solution I was looking for when you buy a 500€+ watch and still doesn’t explain why the 920XT doesn’t have these issues (or at least much less).

Because it has better GPS chipset from accuracy standpoint. 945 has the new Sony with low energy usage, but worse accuracy.
