Frequently Asked Questions
What size arrow should I shoot with my bow?
To find out which arrow is the best to shoot with your setup, visit www.eastonarchery.com and click on the Shaft Selector
Guide. This will walk you through a simple step by step process in order to find the shaft that's best for you.
Bows should not be shot with arrows weighing less than 5 grains per pound.
What is a reflex riser and a deflex riser?
Reflex and deflex are terms used to explain the geometry of a riser. A deflex riser bow will have a higher brace height
than a reflex riser bow which generally means it is a more forgiving bow. A reflex riser bow has a shorter brace height
which usually translates into a higher performance bow and perhaps a bit less forgiving than a deflex riser bow.
Reflex/deflex is measured by the position of the throat of the grip in terms of its location from a line drawn from each of
the pocket pivot points on the handle. If the throat of the grip is in front of the pivot point line it is considered deflex, if it is
behind the pivot point line it is considered reflex.
What is brace height?
Brace height is the distance between the pivot point of the grip and the string at rest.
What is Tiller?
Tiller is the difference in actual distance between the upper limb to the string and lower limb to the string measured from
the base of the limbs (where the limb and riser meet) at a 90 degree angle. Single cam models must be measured from a
reference line from axle to axle.
The main function of tiller is to allow the archer to more easily and comfortably aim during the draw and release of the
shot. Most bows will shoot best with an even tiller which means the distance from the string to the limb is the same on top
and bottom. Tiller adjustments are made by adjusting either the top or bottom limb weight adjustment bolt. For example,
if you have too much tiller on the bottom limb, decrease the weight on the top limb or increase the weight on the bottom.
