I'm curious how accurate folks find their wrist based GPS watches for swim accuracy in terms of distance. I have a 735 and I find that it always is a bit 'short' on most swim courses (I know swim courses are inherently hard to set correctly). I usually put my old 910 under a swim cap, and find it's more accurate. This morning on an easy loop of my local swim hole I got 2100 yards on the 735 and 2350 yards on the 910. This is a difference of 1:40 pace vs. 1:27 pace, which is pretty substantial. In a race it's a lot easier to just go with the watch rather than also put the 910 under my swim cap, and I know it's somewhat irrelevant, as everyone swims the same course on race day.
