Hey CB, Hope you had a great Christmas
Before I got one for Christmas, my next buy before spring was going to be a GPS unit. All I wanted was something to mark fishing spots and provide a safe route through shallow waters, I was actually up at the place where I stored my boat, on "xmas" eve talking to Tom about the different types. I also had that little yellow etrex in mind. ($159.00 at CTC.)
There's a feature called WAAS-enabled, it's new technology to do with the satellite signal (accuracy I believe). The original etrex doesn't have it, He recommended the venture ($189.00) if you don't need maps, that's one step below the Legend ($219.00) that does take maps. I only plan to use it in the boat and since 99.9% of the nautical maps are for the U.S., it wasn't really worth the extra money.
The one I got, the GPS 72 ($219.00) has a larger screen and has more memory than the venture, it doesn't take maps but otherwise compares to the GPS76 which is $50.00 more.(see link in above post)
Are you totally confused now?

I was till Tom explained the basics to me for about an 1hr. I've got some literature here, if I can scan it so it's readable, I'll post it.
My first choice at the time would have been the venture(cheaper), and my second choice would have been the one I got, the GPS72 (more features)
P.S.
My buddy has had the same one as I've got now for a couple of years, and it has worked great.
In fact I've got to program some of his waypoints into mine before spring.
Hope this helps, everything should be clear as mud
