For actual hunting gear it really depends on the hunt. The things I never go without is my binoculars, rangefinder, and one of my Rapid Pivot bipods or tripods. Binoculars are for obvious reasons. I consider a rangefinder with a true ballistic range feature that calculates angles to also be necessary. I have rapid pivot bipod attachments on my rifles and carry either the lighter shock-cord tripod model (I removed one leg) or the adjustable sitting/kneeling model on all my hunts. I practice shooting kneeling from them a lot to get over the grass at home, or sage out west. They work well to put under my binos while sitting to get steadier. I also never leave out my little knife kit with my Havalon barracuda and piranta and their spare blades. I also carry a light baklava and Sitka Traverse gloves even in warm weather.
I have my emergency gear separated into 2 levels depending on what my plan is. If I'm hunting with another person who isn't up for possibly spending a minimal night out I carry light emergency gear. If I'm going solo or with someone willing to spend a night out I add a few pounds for a basic camp. Weather permitting if I find a good buck or bull far from the camp or vehicle late in the day I'd rather stay on him than watch him until dark, hike all the way out, and all the way back in the next morning. This is in addition to what hunting gear and appropriate layering clothing I pack. I like multi-purpose gear and try to shave weight there when possible like leaving out the down jacket when packing the HCG mtn serape. Also I run only electronics that take AA batteries so I can have 2 headlamps, a camera, and a GPS that all use the same lithium batteries if I need to rob from one of them.
