I have the lowrance iFinder Hunt GPS (non-color model) now and the battery life on it stinks. Their website says "up to 12 hours". I get 4 at the most.

I can put in 2 new AA batteries in the morning and they're dead before I leave in the afternoon.

I would like to get a new unit that is better on battery life AND has software available that I can download the waypoints into.

Any ideas????
