There are plenty of gadgets that involve pools, but it seems that most of the ones we see involveor practically except .
So we were pleased to come across the "Lap Track" because it appeared to be something that swimmers--not just technophilic ones--might actually be interested in. This $60 underwater device can be affixed to the wall at the end of the pool and provide a variety of information, including "best lap time, average lap time, average speed, total distance and total calories burned."
The manufacturer does warn, however, that the Lap Track's counter maxes out at 50 laps. Somehow, we don't think that will be a problem for us.
