Lightweight and practical! A serious consideration for safety!


  • Lightweight
  • Affordable
  • Waterproof
  • Multi Tasking
  • Comes with Velcro strap to attach to backpack


  • Somewhat bulky
  • For maximum lightweight, uses Lithium batteries that are expensive

I purchased this a few months ago from ACR where I had previously purchased their PLB. This is a very bright strobe light that can be activated for rescue in dark woods, at night or during the day. It weighs a little over four ounces with alkaline batteries and even less with the longer lasting and lighter lithium batteries. Up to 56 hours of strobe and about 20 steady light on. Visible up to three miles!

Has settings of strobe, steady-on, and sos.




Fortunately, I have only taken this on several backpacking trips but not had to deploy the strobe. Having recently moved back to Georgia and now section hiking the AT, I was surprised by how much forest and closed in woods that is present in the beginning of the AT. I believe this is a useful product and safety tool to have in event of an emergency and might even scare off a bear (unless the bear is wearing a very dark pair of Ray-Ban sunglasses).
