I just bought a Sport Plus. I'm looking for owners with some reviews on it. It seems that I have to be in the water to initiate the computer. The buttons need moisture to work? Any other tips on working with this hopefully fairly simple computer are appreciated. I am not an overly adventurous or deep diver, so I don't need anything to complicated. This one looked pretty simple to use...is it? It's a little frustrating not being able to play with it until I'm under water. I've done the moisten the fingerprints tips thing to activate the watch, but it won't let me play with anything else on it.
