On those units you will need to purchase a video adapter cable that adapts your power cable so it can accept a RCA video input.
At this point Lowrance doesn't have a camera for it and I have no word on whether or not one will be coming.
The most popular cameras we have sold for this are the MarCum and Vexilar ones as they tend to be the most durable. I haven't seen the Go Pro diving box but it would need to be wired to the unit some how. If you can send me a link I'll tell you if that will work or not. The AquaVu micro's wouldn't be the best choice because the cameras are very small and you would need to modify them for them to work well while idling around.
