I can miscount me himself!

First of all: I do not buy the clock here and now also sent back.
The clock looks undoubtedly good, is light and easy to read. There were always five star.
But:
Data can only (!) Be evaluated on the "Garmin-Cloud". This is in my opinion not - or do you now trust any data any company in which you never know what they do with it? (In the end, the health insurance will be more expensive, because the weekly swimming performance does not fit ;-) But well, I'll still take me - I need to use the feature is not so.
The worst part is that the clock is not to be used for their intended purpose. Even if one pays attention to proper use extremely accurate, so clean turns, pushes himself off vigorously and can slide the clock miscounted repeatedly, for me at least the breaststroke. Where is not clear to me, since you can read on the train at the earliest end times. Sometimes a change is not detected, sometimes you suddenly a train more on it. On average, on 10 tracks the clock bib +/- a train. In 25m pools even a bit more! So of course, the results are always easy to see at the end only in total section incorrectly.
If they do not even reliably detects the tail, who knows how many beats there between then not be properly recognized ...
I wonder why they should work so "super" in other, however, many people complain of a lack of counter behavior.
Except as waterproof Stophur the Garmin Swim is not really suitable for me. Firmware is the way, according to information on the clock a 3.80 been.
Possibly have here a few more years until there is a reliable device. Until then, learn to count, or any such thing as a Lap Counter as "Sport Count 100", etc. test, because you have to count then least in his own hands.
