Northstar 951X is the hot ticket, you will not find one better, just so happens, I have one for sale
If you are interested, send me a PM.I tell all my customers to get a Garmin, the 441 and 541 are both nice units, they are color and come with built in charts. I was in West marine yesterday and happended to look at one, i couldn't believe the price, they have gone up quite a bit since hte last time I looked at one. Lowrance is a hit or miss, my friends that install depth finders/gps' for a living tell me all the problems they have with them, but the fishing boards are all about them
PS, I also have an older Ray marine rc320 for sale cheap
