The Marine Guardian manufactures hybrid Cellular/ Satellite security, tracking and monitoring solutions for boats of all sizes. Boat owners and Captains choose our system to protect their boat, gain peace of mind, receive insurance discounts, or in some cases, to meet mandatory insurance requirements for coverage.
Whatever a customer’s priority, The Marine Guardian has a market leading solution.
The Guardian two-way Satellite Technology
The key advantage of The Guardian’s two-way satellite technology is that it continues to monitor and control your connected devices even when the boat is beyond cellular coverage.
The system works seamlessly in both cellular and satellite modes, so you can continue to track your boat, monitor all connected sensors, and arm or disarm your security system—regardless of where you are.
Iridium 2-Way Iridium Satellite Network
Iridium’s unique constellation of 66 Low Earth Orbit (LEO) satellites provides truly global coverage, reaching 100% of the planet. The satellites are cross-linked, creating reliable, low-latency connections that are resilient to weather and can maintain communication virtually anywhere in the world—capabilities that high-orbit geostationary satellite systems cannot match as effectively.
Our devices leverage the Iridium two-way satellite network to provide continuous monitoring and control of connected devices when a boat moves beyond cellular coverage. You can continue to monitor sensors, track your boat, and control connected systems from virtually anywhere.
With systems that rely on one-way satellite technology, you can track your boat beyond cellular range, but you lose the ability to monitor sensors and control connected devices until cellular service is restored.Global 2G/3G/4G LTE Cellular Communication
The Guardian supports 2G, 3G, and 4G LTE-M networks, providing broad cellular compatibility across 142 countries—including all of the Bahamas. This ensures reliable connectivity even in areas where the latest cellular technology isn’t available.
Some systems claim to work in the Bahamas, but may only be compatible where 5G coverage exists. A 5G-only system can lose tracking and monitoring capabilities entirely once the boat moves outside 5G coverage.
Technology
Built from the ground up for the marine environment, The Guardian is designed for long-lasting, reliable performance in the harsh conditions boats face every day. Our devices are built to withstand corrosion, moisture, vibration, and the demands of life on the water.
As a hard-wired system, The Guardian’s sensors are not susceptible to frequency interference and don’t depend on batteries that can fail or trigger false alarms. The result is dependable security and monitoring you can count on—giving you peace of mind while reducing unnecessary alerts for you, marina personnel, dock neighbors, and local authorities.

Real Security Features
The Guardian’s five-point security system is designed to protect your boat—and the valuable electronics and gear onboard.
1. Infrared Security Beam
Designed specifically for exterior use, the invisible infrared beam is ideal for open boats such as center consoles. Strategically positioned at the helm or another access point, it creates an invisible security barrier around your electronics and equipment.
2. Door & Hatch Sensors
Protect enclosed spaces with sensors on cabins, engine rooms, and other doors or hatches where valuable equipment and gear are stored.
3. Theft Fence
The Guardian’s internal accelerometer detects unexpected boat movement, helping identify potential theft or unauthorized movement before it’s too late.
4. 125 dB Siren
The ear-piercing 125-decibel siren features nine distinct sound patterns and delivers an attention-grabbing deterrent comparable to the sound level of a jet engine during takeoff.
5. LED Strobe Light
The bright LED strobe offers 16 different flash patterns, providing an additional visual deterrent and making an alarm impossible to ignore.
Footprint
The small footprint of the TMG control unit and sensors make it easy to conceal on any boat. There are no large wireless or repurposed home home security sensors to be found with our system.
Warranty
Our 2-year warranty ensures peace of mind and satisfaction, keeping our customers happy and confident in their purchase.
