    BM800 Boat Monitor 12-48V with Bilge Sentry Sensor

    • Boat Monitor
    • Bilge Sentry
    • Battery and Bilge Pump Cable
    • Easy Installation

    Runs 24/7 without drawing power from your boat. 

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

    The system runs on an internal battery with up to four months of power and charges itself every time your boat batteries are being charged. In other words, it is completely maintenance-free and will monitor your boat for years without having to remove it to charge.

    Keep Track of Your Boat at All Times

    • Automatic GPS features give you peace of mind
    • The position and movement features are tracked by sensors inside the Boat Monitor device itself. The app shows you the current position of your boat at all times.
    • GeoFence and Triplog features will automatically be updated, so that you always know when your boat is underway, where your boat is, and where it has been.

    Cables Made for  Maritime Use

    • The cable-set connects directly into up to two battery banks and your bilge pump.
    • Our cables were developed specifically to be able to function in harsh maritime conditions and will always deliver data back to the Boat Monitor - regardless of the moisture in the motor room. 

    Simple Installation

    • No screws, no metal components, no problem. 
    • We've designed the installation process so that you can easily do it yourself with the help of a pair of pliers. 
    • With your device, you will receive enough industrial tape to mount the entire system in cases where you don't want to use screws in your boat. 
    • Additionally, we have chosen plastic components across our system in order to avoid eventual sources of rust in the boat.

    Choose your Subscription after Installation

    • You pay your subscription when your system is activated in your boat.
    • Continuous monitoring of your boat
    • Data stream from your boat to your app
    • Immediate notifications when the system detects alarm levels
    • Tracking of your boat if it is stolen

    Your Best Defense Against Water Damage

    • With the Bilge Sentry, you can always see what's happening in your bilge. 
    • Bilge Sentry gives you an exact measurement of water level between 0 and 6 inches. The app shows you the current water level, and data on when the boat began taking in water and how quickly it is filling up.
    • In addition, it measures the temperature in the bilge so that you can ensure that your boat isn't exposed to harmful frost and icing.
