Once again I find myself in total disagreement with Lawdog. :eek: So what's new about that?
More magnification is definitely NOT the answer in my experience. In fact it usually makes matters worse in cheap scopes. You're better off with 20X than 45X and better off with 45X than 60X. Size of objective lens has a bearing here as does quality of optics of course. The larger the objective and higher quality the optics the more magnification you can use.
In low light the higher magnifications tend to make the view so dim it is not clear enough to be useable on cheaper scopes. In bright light it is often too hot and mirage steps in making all over about 20X nearly unuseable again.
I've owned and looked thru the scopes of others a great many cheap spotting scopes. Without exception a 9X riflescope did about as well. If you have a decent 4-12 or 4-16 scope you're better off than with a cheap spotting scope. In fact long years ago we mounted a Tasco 3-9 World Class on a small tripod and used it quite successfully to 100 yards when even a B&L spotter that was a low price one didn't do as well.
I now use a Bushnell Elite 20-60x80MM spotting scope. It is without a doubt the brightest, clearest and highest quality scope I've ever looked thru. But even with it 60X is only marginally useful for the reasons mentioned about. At 60X the exit pupil is only 1.3mm, pretty darn small for low light use even with outstanding optics this scope has. When the temp goes above 80 degrees then mirage takes over and makes 60X totally useless.
I most often set it to 20X to 25X and at those settings can see .17 caliber holes at 100 yards with ease. At 200 yards .22 caliber holes can easily be seen.
I just refuse to recommend ANY cheap spotting scope. You're better off spending the money on a decent rifle scope with a top end of at least 12X to 16X with an AO feature and using it mounted on a small tripod.
People who think their cheap spotting scopes are working just have never looked thru a truly good one.
