Hello I bought gps gw60 watches for my sailing club to create a small speed challenge. The problem is that I can not create several run in the same session, it's complicated to swap the shows on the water. Have some tips or software to solve my problems.

Give GPSar a try. You can split sessions with it and save them separate. 

whoops, no message

I had a charging and use problem with my GW60, thankfully found the forum, very good info.

last use before arm was injured, and no tracking- ah well, back to drawing board, and rest the torn elbow ligament- stiff gear change on the windsurfing van.

anyway

Exmained coupling clamp and found one of the pins was depressed, not allowing it to charge so cleaned with small amount WD40, voila- so far charging well, that is the charging icon is marching at last.
