I am normally a very private person but.....well, you guys are my brothers so I thought I would share. This is a very integral part of my kit for day to day operations. Just in case you happened to get that all important intel in a sealed envelope that you burn later delivered by that poser in shorts that drives a funny looking Jeep.......but he hasn’t fooled you? He wishes you didn’t know but I know that you know that he knows that you know? phew......that made me a little dizzy? I would would provide a link and do a review with a bunch of words I don’t understand on a subject I know nothing about but I have been sworn to secrecy.? Submitted for your approval....
