EagleEye Prototype Photos

Here are the photos of the EagleEye Scope Magnifier. This is the prototype, fully functioning but I’m still working on its final form… The frame contains a Fresnel type plastic lens, this is thin, flat, lightweight and unbreakable. The frame can be elevated, rotated, you can set its position along the tube and the distance from the tube. When carrying the rifle, the magnifier can be rotated onto the top of the scope.

The main advantage is that I can read the sidewheel even with my eyes on the scope, gaining valuable time in a timed shot. I don’t have to take the scope off my eyes, hold the rifle away and read the distance. Instead, I simply read it and dial in, while keeping the rifle on the target! The Fresnel lens refracts the light beam so the Eagle Eye can be much closer to the scope tube than my left eye is, and I can see the whole width of the sidewheel.

This is the difference, photographed from the left eye’s position. Blurred sidewheel because I can’t focus so close any more, but the EagleEye’s picture is twice as big and sharp. Seeing the elevation turret is not so critical because it is not so close to the eyes, but I’m working on a clicks magnifier, too…

Now the magnifier is connected to the scope by a pair of cable ties. I think this method will work on scopes with a rubber scope enhancer, but using this system too much would wear the scope surface, which is not too good on a scope which is worth several thousand quids. So I’ll design a collar fixed around the scope body, and the magnifier will be connected to this part.

You can adjust the height of the frame, using other holes for these two screws. These screws also prevent the Fresnel lens from sliding out to the right. You can take out the lens for cleaning or replacing to a stronger one. The direction of the lens is important because it shifts the picture in a way that you can see it even when aiming.
