ACR C-Strobe H2O — Water-Activated LED Distress Strobe
Fires the moment it hits the water
Free shipping over $75 · ships in 3–7 business days
Best bought alongside something else. Small, light items like this cost nearly as much to ship as they do to make. Add it to a rod or lure order and it rides along in the same box — which is why the free-shipping threshold is $75.
Water-activated, so if you go over the side at dusk you become a flashing target rather than a dark head in the chop — without having to find a switch. ACR states USCG and SOLAS approval, a 45-lumen LED and over 120 hours of runtime.
