SeeLevel by Garnet RV Holding Tank Monitoring System for 3 Tanks Model 709

Received the unit in just a couple of days despite the 7-21 day delivery noted. This takes some technical knowledge and physical work to install, but it works great. I had to cut the panel in my wet-bay in two to get access to the tanks, but once I got access, the installation was straightforward. Positioned the sensors temporarily with blue masking tape to make sure the position was good. My old system didn't work well, so I abandoned any chance of using it again. I "adopted" a pair of wires from that, so I didn't have to snake new wires to the panel. Cut out the old system's section of the panel (again, not for the faint-of-heart) and put the new panel in.

I haven't install it.Two of the three tanks are not accessible. They require cutting out fiberglass siding on the bus.
