Bearshooter,
I'd have to go with Garmin, as others have suggested. I fish commercially in the northeast and rely on gps every time I'm out on the water. I have used many GPS units from different manufacturers and have found Garmin to be my personal favorite. I just purchased a Garmin 60C for an upcoming elk hunt in Montana. I haven't used it yet so I can't tell you much about it. I also own two other handheld gps untis from garmin and they are both good performers. I own quite a few fixed mount gps units, two in each boat, and I've only had a problem with one, I sent it back to Garmin and, no questions asked, they fixed it and had it back in no time. Hope this helps.
