Tech Force airgun scopes - part 1

by Tex Force

Many shooters mount scopes on their air rifles these days, and Compasseco has been an innovator when it comes to airgun optics. In a future post I'll deal with dot sights, but today I want to talk about Tech Force scopes.

Tech Force was a pioneer in rugged airgun scopes
You probably know what a strain a powerful spring rifle puts on the optics of a scope. Airgun scopes have to be specially braced to absorb this recoil and vibration. Tech Force was bracing its scopes long before the major American scope manufacturers got on board, and they're still recognized as rugged optics.

Bright, clear optics!
The description on the Compasseco website tells you that Tech Force scopes are made in the same factory as BSA scopes. What they don't mention (but I will) is that Tech Force scopes are usually BRIGHTER and clearer than BSA scopes with equivalent features (power, lens size, etc.). In the optics field, you get what you pay for, and Tech Force pays extra to get upgraded lenses and coatings to improve visibility. All you have to do is compare a Tech Force scope to another brand to find that the Tech Force scope is just as bright, if not brighter than most of the competition.

"Buy" the numbers!
Let's cut to the chase. Looking at Compasseco's site, you see a lot of scopes. Which one is right for you? Here's my recommendation - unless you have a specific reason to choose a different scope, either theTF 2-7x32mm or the TF 3-12x44mm scope (5th group down on the page) will be perfect! Both are extra-bright and the big differences are magnification, size, weight and price. If you can afford it, I'd go with the larger 3-12 scope, because, just like money, a shooter can usually use more.

Here's what the scope numbers mean
Here is what all those scope model numbers mean. The "2-7" figures mean this scope has variable power from 2x (target looks twice as large as it does with no scope) to 7x. The 32mm refers to the size of the lens at the object or target end of the scope (called the objective bell). The larger the lens, the more light can pass through the scope, making the target appear brighter. If the lens gets too large, it bumps against the rifle it's mounted on, and you have to use very high scope rings to clear the gun. That can be awkward when you have to look through the scope.

Parallax adjustment
Good airgun scopes also have parallax adjustments to keep the crosshairs from moving against the target at a given range. All you do is rotate the knob or bell until the image looks sharp in the scope and the parallax is adjusted for the distance to whatever you focused on. A real airgun scope adjusts as close as 10 yards or closer, and the two scopes I have recommended both focus to 7.5 yards, which is 22.5 feet. That is REALLY close, but if you want to shoot even closer, just dial the power as low as it will go and the target will appear clear as close as 10 feet! That's real flexibility that you won't find in firearms scopes.

I have more to say about scopes, and I'll say it next Monday. Until then, you might take what I've suggested and look around Compasseco's site to compare scopes for yourself.
