I have been hunting for numerous years in CA and AZ for deer and elk. I have a question pertaining to what size type of binoculars you would use for more open areas (without a large amount of thick scrubs like manzanita) for spot and stalk. There is generally lots of grade to haul up gear. Generally I have hunted in Big Bear and Trinity. Does anyone use the larger binoculars (50 or 56 mm) for this type of hunting? I generally use my 8 x 42's, but sometimes I hear activity on a facing hillside just after sunset, and I can rarely pick anything out.
