Review on Standard Horizon HX890 Black Handheld VHF: Advanced Floating 6W Class H DSC Two Way Radio - Top-rated Marine Communication Device by Brian Wright

GREAT boat safety radio, it transmits your coordinates as it transmits. BUT you MUST register online with USBoat or others to obtain an "MMSI Number” that identifies this radio, YOU, and your boat information to YOU when sending or using the one-touch emergency button, and if required for the Use in an emergency, this radio has all the essential functions, floats, lights up. Hopefully you'll never need it, but if you do, it might be worth its weight in gold. Cheap insurance at this price.
