[QUOTE="bruce_ventura, post: 714654, member: 34084"] I would try a good 60/65 mm scope first. My current favorite for backpacking is the Leupold GR 12-40x60 HD. I doubt any 80-85 scope will be better at that range in full daylight. A good one may have an advantage at dawn and dusk, however, due to the larger aperture. The reason I prefer a 60/65 scope for daytime spotting at over 800 yds is that atmospheric turbulence will usually limit image resolution, not the scope. The 80/85 aperture will actually have more turbulence blur, but the higher magnification will give the appearance of a better image. In reality, the resolution will be no better, or even worse than the 60-65 mm image, all else being equal. On rare occasions when the sun first peeks over the horizon or first disappears, the turbulence drops and the 80-85 mm scope will give a spectacular view. Then the turbulence picks up again. This condition lasts for only a few minutes, however. Unless you happen to be looking at a game animal at that exact moment, you will miss it. [/QUOTE]
