I have a fishTV unit that I picked up used last year. I also picked up an old lowrance "little green box" that I plan to use along with it. I also made something to pan the camera with, I made it out of scrap plexiglass I had laying around my shop. It's basically a circle slotted for the camera cable and a few holes to run zip ties or twisty ties to secure the cable. It sits over your hole and as you turn it, it turns your camera. I'd load a pic for you to see it, but I use my phone to get on the site and it doesn't let me upload pics.
