Absolutely. I plan to do the following: Use my rangefinder to ascertain distances accurately and see where that falls on the hash marks to start using them effectively. Yes, I will be using the spotting scope to see exactly where I'm at that way it also gets used. Good thing I'm bringing two people with me, I ran out of hands!
I used the spotting scope already to look at the edges of numbers on a house around 167 yards away and I could see where the paint was flaking off. Pretty good to me.
