"Dominant Eye" Shooting problems are solved here!


Test your
Shooting Eye Here

1. Select a small object (no bigger than a golf ball) some 9 or 10 feet in front of you.

2. With both eyes open and with one arm outstretched, point the index finger at the small object.

3. Without moving your arm or index finger, close and open each eye in sequence.

4. You may notice that only one eye matches the pointing position of the index finger.
That is your Dominant Shooting Eye.

5. For  more precise information concerning the effects of this when shooting, read " About Vass" by clicking here or contact for any quiries.
