The T-H Marine 2-Way Boat Alarm System is theft protection for owners who park their boat at a dock, in a lift, or on a trailer and want to know the moment someone tampers with it. Built around a shock sensor and a two-way remote, it sounds a 128 dB horn at the vessel while sending an alert to the handheld unit up to 3000 yards out. That two-way link is the difference between a noisemaker and a system you can actually monitor from inside a house, a marina office, or another slip. It's a straightforward addition to any boater's marine security setup.
The kit ships with a 2-way remote control, a main engine shock sensor module, and two sensors, so coverage isn't limited to a single point. The shock sensor runs five levels of adjustable sensitivity, which lets you tune it to filter out wake slap and dock movement while still catching a real intrusion or attempted theft. When triggered, the remote signals through sound, light, and vibration indicators, so the alert reaches you even in a noisy environment or with the handset in a pocket. The transmitter reaches roughly 1000 yards, with response notification out to 3000 yards per manufacturer specifications. The components are waterproof for permanent install, and the battery-powered remote keeps the alert mobile rather than tied to the boat's panel.
This is a practical choice for trailer boaters who store off-site, anglers leaving rigs at a public ramp, and owners of high-value electronics or outboards who want an early warning instead of a discovery after the fact. Mount the sensor module on the engine or near valuable gear, set the sensitivity for your slip conditions, and keep the remote nearby overnight. It pairs well with a loud deck-mounted unit from our marine horns selection and rounds out a layered approach alongside other gear in our boat outfitting lineup. Simple to install, easy to live with, and built to alert you before a thief gets far.
The transmitter reaches roughly 1000 yards, with response notification out to 3000 yards per manufacturer specifications. Real-world range depends on terrain, obstructions, and interference, but the two-way link is designed to reach you inside a house, marina office, or a nearby slip.
The shock sensor offers five levels of adjustable sensitivity, so you can tune it down to ignore wake slap and normal dock movement while still catching genuine tampering. Set it lower for a busy slip and higher for a trailer or quiet storage spot.
The 2-way remote uses sound, light, and vibration indicators together. That redundancy means the alert reaches you in a noisy marina, at night, or with the handset in a pocket, rather than relying on a single audible cue you might miss.
The system includes a 2-way remote control, a main engine shock sensor module, and two sensors. That lets you protect more than one location on the boat. The components are waterproof, so the sensors can stay permanently mounted on the vessel.
Yes. The system is built for straightforward owner installation. Mount the sensor module on the engine or near valuable gear, set the sensitivity for your conditions, and keep the battery-powered remote with you. No panel wiring is required to receive alerts.
