Great, only downside: the Garmin connect interface

The pros:
(1) Counting Reliability quite impressive (I'm quite a good long-distance swimmer). The watch is mistaken as troublemakers. In regular swim 0 worries.
(2) Comfortable to wear, pleasant grip.
(3) Widescreen: jarrive to read the full distance in tips! (Well we lose a little time anyway)
(4) Battery replaceable by the user standard button!
(5) Rather discreet. (I does not like me "fart" in the basin).

The -:
(1) The big minus: Interface with the PC. Jai struggled a while before it works (though I'm not a noob). And once it works it is rather limited -> 4/5 from where the damage
-> To know that the TCX files that one can save are actually XML files, working with Excel. You will have a list of all lengths.
(2) ANT + protocol while smartphones are not equipped, requires an adapter for the iPad. If the watch comes with a USB adapter -> no worries about so PC.

One last tip: Especially pause the stopwatch every time you take breaks. Otherwise beware of false counts.
