Bought one of these as Soon as I got my boat. I have barely figured out some of the basics of using a fish/depth finder. I got it more for the depth finder part, I got this model because it was the cheapest one with gps($129). I wanted the gps for speed, tracking and way points and such. The only thing I don't like about it is you can't program coordinates(i don't think anyway) and there is no sd card slot. For the price and being my first one, I am happy with it. I think I need to adjust the angle of the transponder so it reads the bottom better while running on the water.
Anyone have any ideas on how the fish id option works?
