I would like to pass along something I have learned in the past couple of years deer hunting. The newer AAA battery headlamps are the most useful item in my pack.
The tiny powerful headlamps now available are useful for the morning trips to the stand, while climbing, while assembling gear once in the stand and loading shells or setting up archery gear. It is much easier to hike on the cold mornings down a rough trail with both hands available and not have to carry a flashlight. Especially if you are already carrying something (rattling horns, camera bag, seats, etc.)
In the evenings, they are helpful for repacking gear, climbing down, picking up loose gear, signaling hunting partners and most importantly, helping you field-dress in the dusk or dark. I have cleaned deer with a flashlight in my teeth for the last time! :-) We hunt in a rough camp with no electricty or water and the headlamp stays on my cap or hat all night at camp. No need to look for that !*&!?** flashlight. .:lol: For skinning a deer back at camp, it is nice to have a direct bright beam of light everywhere you look with the sharp knife in your hand.
Of course, we have all killed deer without a headlamp, but for the price and weight, they are the handiest item in my pack.
