Definitely do that! 15's are a game change in terms of initial spotting. Spotting scope... to me.. seems like... Ok, now that you've spotted them with the binos... you're picky and you wanna be able to tell this particular one has like this most amazing rack, and you're wanting to verify that part of it... before you set off on trying to make a plan to creep up on him.Well that concludes it then I'm dropping the spotting scope. I do have a buddy that has a set of 15x56 binos might see if i can borrow those.
