Open water swimming
- 
 My suunto 7 it is totally useless in open water swimming I tested it with friends with other gps watch and meters measured by my S7 are always wrong , usually too much than realty but even more important it is S7 lost often GPS signal and trace it is completely wrong …it seem i swim on an island , that it is funny but not right for such a important swatch and brand

 @Grillo54 
 what swim style did you practice?
 my wife’s S7 does perfectly well with crawling
- 
 @freeheeler crawling , only crawling 
- 
 @Grillo54 I used mine open water swimming down the beach but mostly butterfly stoke. I think I also did front crawl and it worked fine gathering GPS date. Try hard reset your watch.

 @BinoWorld-UK thank you , i ll try hard reset

 @Grillo54 
 I tried it and the result was 0 meters in both occasions.

 I remember you can set S7 to record every 10s… not sure if this applies to OWS, too. if this is possible and the setting is 10s, I imagine that the watch will struggle to record reasonably.

 My S9P and my wife´s S7 usually differ +/- 40m in OW swims , her GPS tracks look generally OK
