Cant angle -- The “cant angle” is the angle, from vertical, that the slingshot is
held when shooting (Figure 7-4). Most shooters find it more comfortable to
hold the sling handle at some angle (cant angle) other than straight up
(vertical). The exact angle is not extremely important but consistency is. The
cant angle for different shooters range from zero (vertical) to 90 degrees
(horizontal). Most shooters hold the sling between 30-and 50-degrees from
vertical. There are three important considerations when deciding what cant
angle is best for you. First, is it easy for you to orient the pouch at that same
angle? Second, does the cant angle allow a good reference point (sight) on or
near the sling for aiming? (When using the instinctive aiming technique you
don’t have to be concerned with this reference point.) If one of the forks
obscures the bull’s-eye, the orientation of the sling, or the anchor point, must
be changed. And third, is it repeatable with precision?

Figure 7-4. The cant angle is the angle, from vertical, the slingshot is held
when shooting.

Once you determine the cant angle best suited to you, you must use this exact
same orientation for every shot. In order to do this, it is best to use some sort
of vertical reference. (It’s much easier to judge when a reference is perfectly
vertical than to judge an off-vertical angle.) One of the forks can be used as a
vertical reference (the 30 degree cant angle shown in figure 7-4 is an
example) or some other reference can be attached to the sling. Figure 7-5
shows a vertical reference attached to the yoke of a sling. When shooting, it is
a simple matter to hold the reference vertical thus insuring that the sling is at
the proper cant angle.

Figure 7-5. The vertical reference, on this slingshot, is used to help insure
proper cant angle. (On this slingshot it is also used to attach a sight.)

A bubble-level can be used to insure proper cant angle. The bubble-level can
be glued to the sling. Attach the bubble level to the sling such that the bubble
is centered when holding the sling at the desired cant angle. Bubble-levels can
be purchased from most hardware stores for a few dollars and attached to the
sling with superglue.

When the bubble in the level is centered, the sling is at the proper cant angle.
