The only piece of `hi-tech' electronics I've found to to of any real use is a pair of ProEars Pro Mag LE hearing protectors. I can hear just about everything going on around me and yet don't end up with ringing ears when through shooting. Can't say that I'd like any of the other stuff since with the exception of the `hearmuffs' I've always pretty much traveled pretty `light' when out hunting. Anything beyond what one needs to `survive' is too much. (And keeping one's hearing intact is definitely something towards `survival'.)
