Hey guys I'm looking at getting a spotting scope and I'm trying to decide if I should get one that has a power at about 10-30 or 15-45. I don't want one any bigger than that because I don't think I would take it along much as I'm wanting to take it into the backcountry. An example of how I will be using it is this past Saturday I hiked about three miles out and spotted a group of deer. But they were so far away that I couldn't tell if they were bucks or not with my 10x42 Binos. Basically I would just like to be able to tell if a group of deer has bucks or not because I don't want to hike after them and find out they're all does. I'm not really looking for a trophy so I don't need to count points or estimate a score. I just want a decent buck. Thanks guys!
