We just about fried the one with the removable batteries in the Steeplechase. I think it's still ticking although I haven't spoken to Chris about it in a little while - the battery compartment got soaked after two days of sailing in the ocean. If you do get one, I suggest going with the rechargable one because it's battery is sealed inside - most of them die because water gets into the battery area.

I've been through two Etrex Legends and my current one is on it's last leg. I hope to get a foretrex soon. The charging / programming port is sealed from the inside but is susceptible to corrosion. I intend to fill my ports with vaseline to help keep the water out while underway.
