I own both the G7 and the Terrapin and have brought them both out for several hunting and long range excursions. As has been stated by other posters, I agree that the Terrapin comes into it's own when distances begin to exceed 1200-1400 yards, and I want to have some fun shooting out to a mike. For my long range hunting which rarely exceeds 1100 yards and is predominately 500-1000 yards, I use the G7. Now having shot a couple of dozen game animals within this range window, I am fully confident of the G7's capabilities, and it's substantially faster than manually measuring and entering data in to calculator. I have shot at least a half dozen good animals that i probably would not like have taken without this speed advantage, most all whitetails. My Terrapin is now also a dust collector when long range hunting is my purpose. I won't part with it because I do like playing at ELR where the Terrapin comes into it's own.
