For Target Archery style the index, second and third fingers are used.
The index finger is placed above the arrow nock and the second and third fingers are placed below the arrow nock.
Curl the fingers around the bowstring so that the first joint of all three fingers are aligned on the bowstring.
Keep a space clear between the index and second fingers and the arrow nock, so the fingers do not touch the nock. (This will prevent 'pinching' of the arrow.)
Keep the back of the hand as flat as possible. (Relaxed.)
The thumb is tucked into the palm so it can be placed against the neck at full draw.
Place a slight pull on the bowstring to set the fingers in position ready for the draw. During the draw and anchor maintain an even amount of pressure on all three fingers.

Place the bow hand into the grip of the bow with the centerline of the vee between thumb and index finger in line with the centre of the bow as shown in the top view.
The base of the thumb muscle should rest on the centerline of the grip.
During the draw, the pressure should be taken on the thumb muscle and directly into the wrist. (Low wrist position.)
The thumb and fingers should remain relaxed. If a finger sling or bow sling is not used, then the tips of the fingers are curled around until lightly touching the bow. This will stop the bow falling out of the hand on release.
A consistent hand position on the bow grip is necessary.
