OK, I realize that because of my age and my propensity to accumulate gear, that I may have more of a choice than some, but I would like to know if anyone other than me changes binoculars based on the hunt. First of all, let me agree with so many hunting magazines when they tell you to use the "BEST" optics you can afford. Your binoculars are often more important than your firearm.
For open country mule deer or elk hunts, I carry a good set of 10X42's. I know I'll spend a lot of time behind the class so I want the biggest and best I can get. I want them to be heavy and solid. I also want them to be of a quality that I don't end up with a headache after an hour or so of glassing.
For treestand and most archery hunts where my shots will be closer, I choose a much lighter, compact set of (still very good quality) 8X25's. I figure that the time spent glassing is much less and the distance I look is also less, so I opt for a lighter pair. I don't want that heavy set around my neck in a treestand all day.
If I was going to do some moderate distance hunting, I might even switch to a set of 7X35's or something.
Am I the only crazy guy out there changing binoculars for different kinds of hunts?
