There are a lot of watches for diver out there. Here is finally a watch for Swimmers. The Finis Swimsense Swimming Watch ($199) is the new training tool for those of us who don’t see a pool as a place to relax. The Swinsense uses accelerometers, magnetometers and other algorithms to identify your swim and analyze your performance. Pace times, distances, stroke count, stroke rate, distance-per-stroke and calories will be no secrets to you anymore.
