Optical Booster (new)

Optical Booster (new ?)

I shot next to a gentleman yesterday and he had an Optical Booster on his scope. I did some searches on this website and found some information about optical boosters (http://benchrest.com/forums/showthread.php?t=53761&highlight=magnification+booster). I noticed the date was 2008.

Just wondering if anything has changed (good or bad)? This would be going on a Sightron 36x used for 100-200-300 yd score shooting. I really like the idea of being able to put on/take off. 36x is plenty at 100 - I'm interested in using it at 200 and 300. Any experience would be appreciated. Lastly, anybody have an idea of how much it weighs?

Thanks in advance.

The BullsEyePro weighs maybe an ounce. They are good for increasing contrast of the crosshairs and do boost the scope power just a bit. I have one on a few of my scopes, both Weaver and Leopold. I see no reason to take em off. A warning tho, in poor light they can darken the image a bit. Also I don't like anything bigger than a 3X on a 36 or higher power scope. I cannot focus a 4X on the 36's. I have a 4X on a Weaver T24 and it focuses just fine.

TARGET SCOPES from 6mmBR.com

Exit Pupil: Given objectives (front lens elements) of equal size, the more magnification the scope, the smaller the exit pupil. Remember that the exit pupil, a tiny circle of light, must deliver ALL the optical data your eye receives. Bigger is better by far.

Too small an exit pupil will make a good scope dim and hard to use.

That's why we advise against boosting the Weaver T-36 or the 36X Sightron.

With their respective 40mm and 42mm objectives, the exit pupil becomes too small when they are boosted beyond 36x.

I have the 4X on a B & L 36X.
It's a little much for 100y. But, great for 200y.
It used to screw on. I banged my nose real good once.
Well, more than once.
So now it's held on with 2 band aids. Cushions the nose, too. The rubber boot that came with it, would not fit around the bolt. There is a smaller boot. I just use the band aids.....

abintx: Sorry. Your post does not address the subject at hand. The BullsEyePro goes on the back end of the scope. You are talking about bumping up a scope internally. bob finger

I tried the Gene Davis booster on my Weaver 36X [as pictured below] and sent it back because, for me, the sight picture was worse, then when it wasn't boosted. It looks like trying to boost a Weaver 36X, regardless of whether the attempt is internal or external, is not such a good idea. Art
