Wadar is a wade assist system that uses sonar to measure water depth for driving through floods in a car or 4x4 for river crossings. The bluetooth sonar sensor connects wirelessly to your Android phone, tablet or head unit.

The app displays the water depth both graphically and digitally. It also features customisable car icons. If you want a picture of your own car on the app please email it to [email protected] and we will add it to the app.

The sensor can be mounted anywhere on the car that has a clear downwards line of sight, wing mirrors are a good location.
The sensor can be flush mounted by drilling a 29mm hole, alternatively it can be surface mounted with the supplied bracket.
Just pair bluetooth on your android head unit, tablet or phone and you are ready to go.
