The Sensar Marine Boat Monitor system keeps watch over your boat’s critical systems 24/7 and allows you to check their status directly from your mobile phone. Paired with the Bilge Sentry sensor, the system provides real-time updates on bilge water levels, temperature, battery condition, GPS location, and vessel movement for complete peace of mind. Designed for reliability and convenience, the Boat Monitor operates on an internal battery that can last up to four months between charges and automatically recharges whenever your boat batteries are charging. This means the unit is completely maintenance-free and continues monitoring without drawing power from your vessel.
Bilge Sentry accurately measures bilge water levels between 0 and 15cm and sends alerts if levels become critical. The system also records bilge pump activity and can notify you every time the pump runs. Integrated temperature monitoring helps protect your vessel from frost and icing damage.
The built-in Multi-GNSS GPS receiver continuously tracks your boat’s location, while motion and impact sensors detect movement and impacts up to 8Gs. GeoFence and Triplog features automatically record where your boat has been, including speed, course, time, and location history, viewable through the Sensar Marine companion app.
The companion app, available on both the App Store and Google Play, displays collected data in easy-to read graphs and maps, stores up to 30 days of system data, and includes a three-month trip history. Users can also manage alarms, share boat locations, and receive SMS notifications when alarms are triggered.
Installation is simple, and the system connects automatically through its integrated 4G cellular connection, with no existing onboard internet required. A subscription starting from US$10 per month (bi-annual plan) is required and includes global cellular connectivity, app services, GPS tracking, and system alerts.
Key features include support for 12V and 24V lead or lithium battery banks, low-voltage alarms, bilge pump monitoring, GPS theft tracking, and rust-resistant plastic components designed specifically for marine environments.
Package includes the Boat Monitor unit, Bilge Sentry sensor with cable, battery and bilge pump cable, mounting bracket, setup ID card, mounting tape, and screws.
