I do have a small monocular that occasionally inhabits various kits. It's not really a survival necessity of course but it's there to satisfy curiosity (eg is that an elk?) and occasionally navigation (what does that sign say? Is that a fire tower?).

I guess I don't really have a GHB, per se. And I still need to get my new Crosstrek equipped as some of the stuff I carried in my old car have not yet transitioned over to the new. But a sidearm and a spare magazine is part of my EDC so it's part of the GHB-type gear. Ditto a knife and flashlight.
