Ok guys, looking to buy new fish finder. Looking for ideas. Thinking I want down imaging and GPS. Don't know if I want some for front of boat or at the console. Would love something that could move back and forth, but I don't know if they make anything like that. I mainly slow troll spider rig, fish over brush, and fish laps. Also fish a lot at nite for crappie and cats. Willing to spent 500 to 800, would put in it but I want to buy an ipilot trolling motor later this fall. Momma will only get so many new toys, have space them out abit. Thanks for any advice.
