What a great little piece of tech - I don't know how we got by without it in the past. No more guessing how full the holding tank is or having to clean icky tank senders. This little bluetooth RADAR sending unit mounts on top of the tank and connects wirelessly to our Victron Cerbo.
Setup is super easy, push the button on the unit so it can calibrate to the tank then enable bluetooth and set up your rank dimensions on your Cerbo. It's as easy as that.
We've had it installed and running for about two weeks now and couldn't be more pleased (We like it enough that I ordered a second one for our water tank.)
