Mo's Bottom Line (BLUF)

The RescueME PLB1 is the smallest Personal Locator Beacon in the world. It fits easily into a life jacket pocket, providing 406 MHz satellite rescue capability for individuals.

Big Power, Tiny Package

While an EPIRB is registered to the vessel, a PLB (Personal Locator Beacon) is registered to you. If you go overboard, the boat's EPIRB isn't going to help you. The Ocean Signal RescueME PLB1 is so compact that there is zero excuse not to wear it.

Unobtrusive Safety

The beauty of the PLB1 is its size. It's smaller than a deck of cards and weighs next to nothing. You can strap it to your inflatable PFD or stick it in foul weather gear, and you'll forget it's there. Despite its size, it packs a 7-year battery life and transmits on both the 406 MHz satellite frequency and the 121.5 MHz homing frequency, plus it has a high-intensity strobe.

Pros and Cons

The Verdict

If you boat alone, sail at night, or fish offshore, the PLB1 is mandatory personal gear. It is the most compact insurance policy against disaster you can buy.
