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 info@vass.ie for any quiries.

A: Extension Bar.
 
B: Disc sight locking screw.
 
C: Disc sight.

D: Anchor frame.
 
E: Anchor locking screw.

1. Ensure that all ammunition is removed from your shotgun.

2. Loosen the Anchor frame locking screw (E) and slide the anchor frame (D) on over the front barrels
    of your shotgun.

3. Hand-tighten the anchor frame locking screw (E).

4. The disc sight (C) on the extension bar (A) is preset at 57 mm (2.25 inches) from the centre of your
    shotgun rib which is an average location. Erect a stationery target some 30 yards or metres away
    from you and preferably with a facility to show the pattern of the shot.

5. Load your gun with one cartridge and discharge it at the centre of the target with both eyes open
    and aiming with Disc Sight (C). Examine the shot pattern on the target to establish whether Disc Sight
    (C) needs some side adjustment to right or left. If the shot pattern appears left or right of centre move
    Disc Sight (C) towards or away from gun barrel. Repeat as necessary until the unit is fine-tuned to
    your satisfaction . Please note that this procedure is essential before experimenting with
    clays or any other moving targets
.
 
6. Likewise, without changing your normal shooting stance, Sight C can be adjusted by loosening
    Lock-screw B & rotating Disc Sight C to correct any upward or downward shot pattern results shown
    on the stationery target.

7. Right-handed users with left dominant eye should fit the VASS with its extension bar on the left.
    Likewise, those who are left-handed with right dominant eye should fit the extension bar on the right.

Locate extension bar A on left. Depending on extent of stock cast estimate location for disc C and zero it as per fitting instructions.

NOTE:
Whether your sport is clay-pigeon, game shooting or wild-fowling we recommend some practise with clays before you will fully
appreciate the significant advantages of VASS (‘The Variable Adjustment Shotgun Sight’). Such practise should only be undertaken
after you have zeroed in the VASS as illustrated above.
