This morning I swam with my new Garmin Swim watch.
Pretty decent overall. I customized a screen, but unfortunately didn't use the Rest timer function so had to depend on looking up at the wall clock more.
Also got spoiled with the Swimsense's auto lap/stop function. Had to retrain myself to hit the pause button after each interval.
Still no issues, worked great in the pool.
One issue I'm working out is the syncing with the ANT stick. I have my Garmin 910XT synced to my mac, but it is not recognizing my Swim watch. checking on that now.
