Need one for the kayak nothing to exspensive but works well and not to complicated.I heard about one don't no what its called,I guess the transducer mounts on the inside of the kayak. Any suggestions

a stick, hold it in the water and see if fish hit. Like the old dudes herring fishing

I hear Flap is one hell of a fish finder.:laughs:

Look at the Eagle Cuda 242, around 80.00 at walmart, but can be on sale there much cheaper.......
