Delta Distance Test
The Delta Distance Test requires two targets. LTI recommends that the first
target should be 150 feet from the shooting mark, and the second should be
175 feet from the mark. See Figure #23. If there is not enough space available,
that specific distance is not crucial. However, the distance between the target and
the shooting mark must be a multiple of 1 foot, not a fraction of a foot.
Refer to Figure #23 as a guide for positioning the targets and the shooting mark.
1. Install the farther target.
2. Measure 175 feet to the shooting mark and mark the shooting spot.
3. Measure from the shooting mark 150 feet to the second target.
4. Mark that spot and install that target.
