What power binocs do you like for spotting deer and elk in the rocks and trees at 1/4 to 1 mile? I don't care about accurately scoring or seeing every flea on them - just finding that mulie buck or bull bedded in the shade under a cedar/spruce/pinion/juniper/deadfall up in the craggy/alpine country. I have had Swaro EL 10x42s and they work pretty well but there were times I wished I had more power. Assume seated with bipod or tripod. The 12x ELs and 15x SLCs are much bigger and heavier. Are they overkill for what I describe?
