I am right eye dominant and Look through my rifle scope with the right eye. For whatever reason I cannot close my right eye and keep my left eye open! Therefore if I use a spotting scope to help see mirage, I have to look through my right eye as well. Anyone have this problem? what is the best configuration? thoughts?
Thx Ted.
Cliff Notes: use both eyes, try a piece of tape on your glasses, avoid eye strain.
Ted - I shoot Smallbore Prone, High Power Service Rifle, 300M International, and 10M Air Rifle. In smallbore prone, and now service rifle, competitors are allowed to use a scope during certain stages.
Even when shooting on e-targets, I still use a 27x LER Kowa scope, focused about 10-15 feet in front of the target to check mirage. I am RH, using my right eye for either the rear diopter sight & iris, or a 40x scope for the second day of smallbore prone. In service rifle, I have begun to use the rule limited 1.25-4x scope. My goal is always to shoot with my right eye, and check the spotting scope with my left.
I learned this from other smallbore, and 300M/Air Rifle shooters, to include German Salazar, who advised that the less you have to lean over or move your head off the cheek piece, the less you'll have to rebuild your position. It has worked well for me, and helped to diminish some cheek pressure high/low shots on the soul-crushing international targets.
I wear the olympic styled frame and lens combination eye protection, with an ISSF legal 40mm blinder over my left eye. It doesn't completely block the left eye, and I have learned that it only needs to just 'dip' into my left eyes field of view to be effective. Many shooters experiment with this, by
using a piece of scotch tape placed in the middle of their shooting glass lens just over one eye.
The reason I asked about using both eyes, is
because that's how our eyes are designed to work - as a pair. Long strings of fire with one eye closed are really straining your aiming eye, particularly on bright days.
Give this a try next time you go out, and see of you have any success: imagine dividing your left eye into an upper and lower half. Place an opaque piece of scotch tape over the upper half of your shooting glasses. Now position your spotting scope so that it's somewhat under, and to the left of your left eye. This will allow you to check the mirage, and bring your eyes back up to your rifle scope, with little-to-no head movement.
