Title: Works well unless you're under water
Review: Bought mine sometime around Christmas and took it into the water for the first time on a trip to St Thomas last week. It died within 10 minutes of being in the water. It was never more than 5' down while I was snorkeling.While I never tested the compass or thermometer against known "accurate" ones, it seemed to work well enough for my purposes. Just keep it dry.
