I am looking at purchasing a spotting scope. I will be shooting from 600+ yards up to 1200 yards. Firstly, should I get a spotting scope or binoculars? Also, what are some of the best value-for-money spotting scopes that are capable of spotting impacts at 600+ yards? Also, if there are any accessories that are must-haves, please let me know. Appreciate the feedback. Buget for the scope/binos would be around 1200 to 1500.
