How It Works
Up and running
in minutes.

No marine electrician required. If you can connect two wires to a battery, you can install HullSense.

01

Mount the device

Connect HullSense to your boat's 12V or 24V battery using the included terminals. Mount the compact enclosure anywhere in your electrical compartment.

02

Pair with the app

Download the free HullSense app, open it near your boat, and tap Pair Device. Registration completes automatically over Bluetooth in seconds.

03

Monitor from anywhere

That's it. Check in from the dock, the bar, or across the country. Battery, water level, GPS, and weather are always a tap away.
