Boat Monitor with Bilge Sentry

The Boat Monitor is the system's brain - where data from the boat is continually collected and sent to the app.

The system runs on an internal battery with 40 days of power and charges itself every time a boat's batteries are being charged. In other words, it is completely maintenance-free and will monitor the boat for years without removing it to charge.

Features:

  • The boat monitor can monitor up to 2 batteries and bilge pump activity
  • Provides position of boat utilizing all available satellites
  • Geofence which alerts boaters if the boat leaves a specific area (fully automatic function)
  • Visualize the current trip and see the history of previous voyages
  • The unit has an integrated accelerometer that displays G-force (measurement area: 0g to 8g)

Cables Made for Maritime Use

The cable set connects directly to up to two battery banks and the bilge pump.

Sensar's cables were developed specifically to be able to function in harsh maritime conditions. They will always deliver data back to the boat monitor, regardless of the moisture in the motor room.

Keep Track of the Boat at All Times

Automatic GPS features give users peace of mind.

The boat monitor has sensors that track position and movement, which allows the app to show users the current position of the boat at all times.

GeoFence and Triplog features will automatically be updated so that boaters always know when the boat is underway, where the boat is, and where it has been.

Simple Installation

No screws, no metal components, no problem.

Sensar designed the installation process so boaters can easily do it themselves with the help of a pair of pliers. 

With the device, users will receive enough industrial tape to mount the entire system in cases where they don't want to use screws in the boat. 

Additionally, Sensar has chosen plastic components across the system to avoid eventual sources of rust in the boat.
