Yeah they are. I keep hoping to find a deal on the Walker system but haven't come across anything cheap enough that I want to spend the money for it.
Maybe this winter I will be able to figure out how to make the camera I have work so I can modify my downriggers to work with it. The camera isn't anything special but the cable is. It is a braided stainless cable with 2 small wires inside. It is about the same outside diameter as a 14 gauge single strand jacketed wire so it isn't that much larger than regular downrigger cables. I figure it would be pretty easy to glue some brass rings to the bottom side of the spool and solder the wires to the spool. Then have a spring loaded "Brush" run on the rings as the pickup and mount a plug on the bottom of the downrigger to plug the camera into the monitor. The biggest problem I have right now is finding out how to wire the camera as I can't find a wiring diagram. Also, there are only 2 wires coming off the camera so I have to believe this should be pretty simple.
