24/7 Realtime Boat Monitoring

Referral -  Image – 7

The Boat Monitor is Always On

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 40 days 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.

Your Best Defense Against Water Damage

With the Bilge Sentry, you always can 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.

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. 

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 of 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.

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 recieve 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.

5 Year Product Guarantee

We know you’ll love our products as much as we do. So much so, that if there's anything wrong with your hardware in the first 5 years, we'll replace it for free.
