Booster Installation Instructions & Adjustment for Best Performance

for the BulzEyePro® ORIGINAL Optical Booster™

Booster Installation - Universal Housing (rubber)

Release eyepiece lock ring and screw lock ring clockwise until end of threads. Now turn eyepiece clockwise and screw to lock ring. Simply slip the housing onto your scope's eyepiece until the housing stop reaches the eyepiece (the housing stop is located approximately 3/16-inch in front of the lens).

After proper installation, point scope at the sky (do not look through a window or screen), turn eyepiece out (counter-clockwise) until the crosshairs become solid and dark with crisp edges.

Booster Installation - Factory-Look Housing
Competition Series(aluminum)

Release eyepiece lock ring and screw lock ring clockwise until end of threads. Now turn eyepiece clockwise and screw to lock ring. Install Booster as per package directions, by screwing on the booster to finger-tight.

After proper installation, point scope at the sky (do not look through a window or screen), turn eyepiece out (counter-clockwise) until the crosshairs become solid and dark with crisp edges.

Adjusting Your BulzEyePro Booster for Best Performance

After proper installation, point scope at the sky (do not look through a window or screen), turn eyepiece out (counter-clockwise) until the crosshairs become solid and dark with crisp edges. Remember to look at your crosshairs only for a split second and then look away (the longer you look at your crosshairs, your eyes will adjust to a less than perfect picture). Take your time and make sure your crosshairs are clear, crisp, and black. Set your lock ring. Your eyepiece will need no further adjustment. This process should be repeated each year or at any time your crosshairs are less than perfectly clear and dark.

How to Become an Expert with the BulzEyePro Optical Boosters

Adjusting to Zero Parallax

Place your firearm into a rest that will hold your firearm without movement. Adjust your rest so that your crosshairs are on the bullseye of your target. While adjusting your distance focus, bob your head up and down. You will see your crosshairs moving up and down on the target. When you are at zero parallax, as you bob your head up and down, the cross hairs will NOT move on the target. Proper adjustment of parallax ensures that you are pointing your firearm at the exact same spot every time, at the exact same distance. When the distance changes so will the adjustment of parallax. Unless otherwise specified, scopes without parallax/focus adjustments are set at the factory for zero parallax at 150 yards. Any other distance will automatically have parallax issues. You can alleviate this parallax issue by drawing your eye away from the scope until you have a tiny hole to see from through your eyepiece (the eyepiece gets dark from the outside and closes in until there is but a tiny hole to see through). This technique insures that your eye is centered each time you site your target.

"Kentucky Windage" and "Mirage"

At short distances, wind flags can be helpful but difficult (if not confusing). At long distances, the wind will change long before you can read all the flags and get a shot off. The answer... In the old days it was called "Kentucky Windage". Today we add Kentucky Windage (prevailing wind) to mirage. Different densities (temperatures) of air have different affects on wind drift and bullet drop. Learning these differences and their affects will enhance your ability to hit the bulls-eye at longer distances.

The BulzEyePro™ Optical Booster™ Advantage

It took us years to design a lens that would at least lessen the effects of mirage on the target. While doing so we discovered a unique quality of a certain polymer manufacturing technique that would place a fine black line on the leading edge of each layer of mirage. Then we were able to enhance this polymer so that it would, first, disperse the target moving effects of mirage. Second, allow us to see the leading edge of each wave of mirage (so that we could see wind speed and direction). And third, discover the differences in air densities throughout the mirage (adjust for bullet drop). This last enhancement has become "the cats ass" to long-range shooters.

Presbyopia

What is presbyopia?

By the time most people reach their 40s, the natural process of aging begins to affect their vision. The crystalline lens is what allows the eye to focus. As we age, our crystalline lens thickens and progressively loses its flexibility to the point where we have trouble focusing on near points. This is known as presbyopia. Nobody escapes it – men and women, people who already wear glasses and those who don’t. Our vision will diminish, then stabilize around 60 years old. This is natural.

Seeing naturally with presbyopia.

A BulzEyePro® Optical Booster™ utilizes the latest advances in technology to maintain natural eye movement in a lens that is indistinguishable from single-vision lenses. Now you can see as well as you did before presbyopia. This is just one of the many issues that are addressed by the BulzEyePro Optical Booster.

How do I know I have Presbyopia?

When you start having difficulty focusing on near points.
For many people, signs include difficulty reading in low light environments (such as restaurants) or having to hold a book or newspaper at arms length in order to read the text. Presbyopia is not a visual defect, but rather a natural aging of your eyes.

How do I correct presbyopia?

The only solution is the use of lenses that increase the ability of the eye to focus. Bear in mind that as your presbyopia evolves, you need to check the eye piece placement on your rifle scope every 2 years. The many other issues like parallax, target movement from mirage, light gathering and placement, high performance prisms, wayfaring and sandwiching, and a number of others will not require any further adjustment as long as you have adjusted your eye piece and parallax/focus for a clear, crisp reticule and picture every year or two.
