How much further can you really see?
I’ve seen so many people on firing lines with spotting scopes complain about the optics they have and what they should have gotten or what they wish they knew before getting a scope. Sometimes people have this idea that having an optics magnify 45x will make things easier to see at great distances and any experienced observer know that isn’t true. Magnification can become void due to heat and mirage and even zero magnification can cause you to have trouble hitting an object at certain distances.

One thing you may want to consider if you are expecting to use a spotting scope for long ranges is a different type of target other than paper. Shoot N C targets can help improve your visibility and avoid any frustrations in trying to pin point your point of impact on paper. They aren’t re-useable so you’ll have to expect to spend more money on them, but they work. Spottings scopes are as good as the money you pay for them, but make sure you know what you can realistically do with them before you select one.
