If you spend any time on the water at night this is by far the best option for the dollar. Easy install, 3 wires. Easy update and configuration. The only issue I had was a Garmin issue, not a Sionyx. I was hoping to put the video into one unit and be able to see it on any of them. Turns out many units don't share video on their network.
Please watch the video till the end, there is some lightening that puts it all in perspective.
