The ACR SM-3 is a USCG/SOLAS/MED-approved LED strobe designed to mark a crew-overboard position with high-intensity light visible up to 2 miles in all directions. It activates automatically on water contact, rights itself to float upright, and runs on user-replaceable AA Lithium batteries — giving it a longer service life than disposable alternatives. A secure mounting bracket keeps the SM-3 accessible and ready for immediate deployment in any conditions.
