Hmm whatever floats your boat.
I prefer to use a non mapping unit and connect it to a laptop with Ozi
Explorer running if I desire.

I have to agree with Bill on this one. The handheld mapping unit is really
nice. Your laptop is far better, but you can have the 76 at the wheel, in your
pocket and so on. Ganzy is one of those guys who has nothing nice and would
prefer it if no one else did either, so ignore his advice. The price penalty is
TINY. We just bought a little green gecko as a backup off Yahoo auctions for 66
bucks. Works great.
The GPS 76 also floats, has a good sized screen and easily accessed charts.
Nice.
