I Just took an Active Shooter course that recommend CAT Tourniquets. Right after I get the chance to not only review one. Its funny how that works
This CAT tourniquet is a proven design that allows someone to apply it to themselves using only one hand. However, it is not the original.
It is under $20, and sturdy enough for the use it was designed for.
I am going to put one in my tool bag (where I am most likely hurt myself), as well as put one in my range bag.
I certainly cannot recommend having one enough.
