ACR C-Strobe™ PFD - Light Water Activated Personal Distress Light

Model: 3964.1
UPC: 791659396414

With 3 modes of operation (strobe, steady-on, SOS), the C-Strobe H2O boasts a 45 lumen LED that operates typically for 120 hours continuously in strobe mode. The C-Strobe H2O model includes two activation methods; the light can easily be activated with a simple push of the On/Off button or when in the armed position, can be activated automatically when immersed in water, making this an ideal light for all outdoor enthusiasts.

The slim, lightweight and versatile design fits easily in a pocket or hangs discreetly when attached to a life jacket or backpack. The flexible lashing loops on the side of the product allow for multiple mounting options including the webbing on your backpack or straps on your life jacket. The Velcro® strap can be secured around the lashing loops and creates countless additional mounting possibilities. The light also comes with a clip designed to conveniently slide over your inflatable life jacket’s oral inflation tube for storing your light inside your life jacket.
