You clearly aren't a rescuer. In Alaska an ELT brings the Air Guard in Pave Hawks and C-130s with para jumpers and battlefield medics. A PLB gets dispatched to State Troopers, who may send a VPSO out on a 4-wheeler. An ELT will bring help whether you survived or not. A PLB will only help if you remain conscious (or survive) to activate it. BIG difference.
I have a day pack with 500 magnum, sat phone, and an Inreach, headlamp, Leatherman, a couple of protein bars, a bottle of water, and season appropriate gear (raincoat, gloves, hat) that goes on every flight. For venturing out away from civilization I also have a survival pack that goes in the back with a Wiggy's sleeping bag and a Hilleberg Bivanorak. Water filter, stove, a small pan, Blast Match, Wet Fire cubes, knive, hatchet, first aid, water, spam, snickers, nature valley bars, parachute cord, a sil tarp, mosquito nets, some fishing line and lures, etc. Alaska law requires survival gear. I don't agree with all of it and think other items should be included so I take what I want and comply to the law for what I otherwise wouldn't take.
