fishfinder frustrations/help

[doggmann]

I had a small humminbird matrix 17 that came with my kayak. It worked fine but i liked the idea of using GPS too. So I took the unit off my boat wasting in the driveway. Low and behold the unit worked but I couldn't get the GPS to work and the unit would only work for a few hours before it would conk out even though the unit used .750 amps/hour and the battery was rated at 12 amp hour. I am throwing my hands up and think a new unit would be the way to go.

Any opinions good or bad on the lowrance elite 4? I figured I'd stay with lowrance since I have some maps for the west coast stored on the SD card from the old unit.
