I reasearch a lot before I bought my Lowrance Expedition C. It's the same as the Hunt C, but cheaper. The only thing is you do not get the camo. Istill have icons for tree stands and such, and you can name them anything.
just so you know, as far as traveling in the truck, you will not get a "turn-by-turn" navigation from it. i keep mine in the truck all the time, and it helps a bunch, but when you do a search and travel to that location, it just shows a 'as the crow flies" line rather than turn by turn. I have not had any issues with reception, but I did put an external antenna ($15) right when I got it. I got mine with the Mapcreate 7 software also. You can put the entire US on an SD card to have in it all the time. I also went with Lowrance because of the lakes information. They have included a bunch of topo info for many local lakes for fishing.
Good Luck
