I bought this before my move to Florida in december, it has not been used, it took a few boat rides before i left, thats about it.

I have the manual. This is the only unit that floats, that I am aware of.

It has 8 megs of space to load in various maps, and also comes With a built in map.

You can see the unit at

I am taking reasonable offers, or a trade for a comparable digital camera.
