Yep, I have an EPIRB in my boat but because I am a shift worker and often off on adventures by myself during the week 4wding, boating, kiting, SUPing etc, I also have a PLB (Personal Locator Beacon) in a pouch which I attached to the strap on my PFD.
I am usually wearing the PFD & PLB combo when in the boat (even though I have the EPIRB), or if I am SUPing or kiting way offshore or somewhere remote.
Sometimes it is just threaded onto my harness strap for kiting offshore, when I am not carrying it, it lives in my 4wd.
I may sound paranoid but as a former sea rescue skipper, I know it is a small price to pay for something that has the potential to save your life.
This is the one I have but I paid less than that when on sale.
