My Garmin swim watch bit the dust. (Warning to anyone who has one - make sure the back is really snapped down after you change the battery or it will get water inside...like mine did!) I really enjoyed having this as a tool to keep track of what and how I swam at each workout. But I'm debating replacing it with the Swimovate Poolmate Live...which appears to have an option for open water swimming. Has anyone used either of these watches, or both, and have an opinion to share?
