1) IFAK (2 TQ, Quikclot , Israeli Bandage, athletic tape, bandaids, gauze, 2 sets of blue rubber gloves)
2) Star wrench for SIG Romeo5 (in butt stock compartment on AR)
3) Extra battery for above (in butt stock compartment on AR)
4) Towel for face ( I swear plenty)
5) 2 Sharpies (someone always needs 1)
I was looking into buying a Leatherman/multi tool.
Was mostly referring to tools to work on guns, but I also always have an IFAK w/TQ in my range bag as well as usually have a smaller one kit and TQ on my belt if I'm shooting in the action bays (not for USPSA/IPSC though). I also have a "fuller" one in my car. Which is a good reminder since it's been a while since I've checked and replaced items in that one. Always wary that being in the hot sun during the week will degrade some of the items.
I too usually have extra batteries for my rifle optics as well as electronic ear pro. I have found that I need to change the batteries of my ear pro much more often than anything else since I use it often. I recently bought a bunch of lithium AAA and AA, so may be good time to switch out just because.
You "swear plenty"? And how does the towel help that?
Just kidding. I get pretty sweaty as well. While I've somewhat gotten used to the sweaty hands and shooting, certainly good to have towels on hand.
Sharpies always come in handy.
Leatherman tools are great, but can also be pricey. Gerber is an economical alternative. I have both and I am able to put Gerbers in my range bag, car bag, etc since they aren't that expensive.
