I have four weeks before acquired the clock because I wanted to spare me the track counting (distance 2500m). according to Internet research, I then decided to use the Garmin Swim. So far I have not had products from Garmin but the name had a certain sound for me. After intensive study of the instructions I failed already when installing the synchronization software. Garmin asked for subsequent experiments and remained until today so.Trotzdem I did my swimming training. The default setting for the 50m lap pool set, pressed buttons, Start signal awaited launch. First time swum highly motivated but imperceptibly the measurement and was stopped after 100 meters. F WORD! OK teething problems of a 50 + float! Next time-most intensive study of the instructions and glasses taken into the pool: Accurate operation with glasses, then changing to swim goggles. Start procedure performed accurately. Start! 2500m breast swimming in presumptive best. I indeed had only huge-scale and thus readable for me pool clock and my unsafe train counting as a basis, so even 100m surcharge. Stopped clock, leaving water, put on goggles and F-word! After 100m, the clock has stopped again to measure. Even the swimming style is not detected again, PS: I swim exclusively BREAST without change and stylistically CLEAN! And so it went on and on ...... The repeatedly highlighted in the reviews motivation was unabated and even increased, in so far as the clock fulfills one point, but for me it is more likely in the meantime become a big nuisance and no help. I can no longer return because I have tested them for too long, but it is absolutely not become a useful Untensil for me. I now use 5 rubber bands on the forearm, which I. From left to right change and the multiple I do not train for Olymoia yes and it's wonderful!
