Remaining observant (aka situational awareness) is something we all appreciate the value of. It is something that we practice (to various levels) as part of our every day routine, especially while carrying.
While our immediate environment can be observed with the naked eye, I have had times when I wanted a closer look at something further away. It was at these times that I thought a small, hand-help magnified optic that could be carried in a pocket would fill such a need. Since most binoculars are not so easy to EDC, I began to look at monoculars. The one that has captured my attention is the Vortex RECCE Pro, which appears to be high quality, range estimating capable, designed to be carried on a belt or perhaps in a cargo pants pocket.
Does anyone here carry (regularly or occasionally) some kind of observation device, or perhaps just keep one handy in their vehicle?
