I'm a fan of 4-16 scopes, but that's mostly due to punching paper. For hunting, I leave the scope on 8 power. But this past Sunday I was sipping my coffee and watching does eat corn, and here came two more deer (I mentioned this the other day) and just from force of habit I used the binocs to look them over. Not Doe at all, and I suspected that the larger one was the spike I'd been looking for, but just could not tell with the 10 power binocs. Cranked the scope to 14 or 16 and was able to be sure that one side was a spike. A 3-9 scope would not have done the job. Not trying to start a grump session on what scope or scope power range is best, but just to say that this was one time that higher power really helped out.
