It looks fun to play with, but is it practical in the long run? Regardless, it won't make them bite.
Do you need one fishing from the shore? For that kind of money you could buy a lot of beer ;D
That's pretty cool. Less cumbersome than the old portable ones we used to take with us lake fishing.
I hate fish finders though. It's a medium to hear fish laughter .... *beep *beep beep beep *beep ... (no bites) ... >:(
if you can cast it you can locate drop off and troughs, submerged kelp and rocks to avoid as well.
I've never really used a FF to look at fish, just depth and structure. well, bait balls too.
