Using state-of-the-art electronics and a 3 cell Lithium battery, the SEA 406 MHz EPIRB combines the strength and durability required for a fully compliant GMDSS EPIRB with modern compact styling. The result is a fully featured EPIRB with a small mounting footprint.

For GMDSS compliance, the SEA 406 has a slimline fully enclosed float free housing which allows self testing of the EPIRB without removal from the bracket. The SEA 406 is also available with a quick release bulkhead mounting bracket for carry off situations.

The SEA 406 is a third generation satellite distress beacon manufactured by McMurdo Marine and designed to operate in conjunction with the COSPAS-SARSAT international satellite search and rescue system. This system locates beacons transmitting on the 406 MHz frequency to within 5km (3nm). Once Search and Rescue (SAR) units are at the distress scene, the beacon's 121.5 MHz homing transmitter and its high intensity xenon strobe light aid final location even in poor visibility.

The SEA 406 is fully compatible with the COSPAS-SARSAT and Global Maritime Distress and Safety System (GMDSS) regulations and meets the latest requirements A. 810 (19) of the International Maritime Organization (IMO).

When shipped, the beacon is programmed with a unique serial number which must be registered with the national authorities. Where national authorities allow, the beacon can be re-programmed with the vessel's satellite or radio call sign. This is done by the distributor using an infra-red light pen connected to a Windows based computer.

The SEA 406 is supplied with a fully enclosed automatic float free housing which allows the EPIRB to be self-tested while in the housing. For non GMDSS use, the SEA 406 can be supplied in a quick release bulkhead mounting bracket, or in a non automatic version of the fully enclosed housing.

Once removed from its mounting bracket, activation is automatic by immersion in water or manual by a protected push button on the rear of the EPIRB. An additional self-test button runs a short diagnostic check and indicates the EPIRB is ready for use.
