@larea it is primarily for fishing and backup for depth. Backup for chartplotter. My primary Chartplotter is a Garmin 5208. I went with the transom mounted for a few reasons. Temp, ease of mounting, didn't want to conflict with existing depth finder and oh did I mention cost and @rasbury funny my invite to go fishing with you must of gotten lost in my spam folder. Dang rub it in will ya.
@Dude_Himself no pics. I mounted it about 3in to the right of the drain hole and inline with the bottom of the boat. The one thing i didn't do that i would highly recommend if your boat stays in the water is to paint it. Spray the metal with a protective coating suitable for metal and then put an antifouling paint on the bottom plastic designed for transponders. Not the normal bottom paint containing copper though. I had to pull my boat out of the water due to an accident and was surprised to see that the barnacles loved it.
