Recently purchased a 735 as the battery life on my 920Xt was dwindling.
For open water swimming the 735. Recently when swimming with a mate we noticed that his 735 was consistently measuring shorter compared to my 920.
Yesterday I swam with both watches. The 920 measured a distance of 3077m and the 735 much shorter at 2881. Both watches are set at a sampling frequency of 1 second and have GPS + Glosnas enabled.
Google earth indicates that the 920 is giving the correct reading.
Is there any way to fix the inaccuracies of the 735
