Like the title says, How often do you use your spotting scope? I have 10x42 bino's and a tripod that i use for scouting in western Washington, but I'm going to be scouting out East or in Idaho and I'm not sure if buying a spotting scope is worth the investment. Can i get by with 10x42 binos held steady on a tripod, or is it worth the amount of money to get into some Vortex Razors?
