Tuning
This section includes step-by-step tuning procedures for obtaining optimum performance and accuracy from your bow and arrow setup. Also included are equipment setup tips, and suggested solutions to most bow tuning problems.

Choose Your Shooting Style.
Tuning procedures for the three mostpopular shooting setups are described and abbreviated throughout the manual as follows: x recurve bows, using finger release (RF) x compound bows, using finger release (CF) x compound bows, using a release aid (CR) You will notice that some of the techniques of bow tuning apply to all types of bow setups and others apply to just one or two types. When separate tuning procedures are required forspecific setups, find your setup within the topic and follow those specialized instructions.

Install All Accessories
Before you start any bow tuning procedures, besure to install all accessories on your bow, i.e., the correct bowstring, bow sight, stabilizers, arrow rest, cushion plunger, etc. In other words, install all the items you intend to use when shooting. Any adjustments made to the bow or changes in bow components can affect the tune of your equipment. When tuning, it is very important to change only one variable at a time!

Maintenance & AssemblyThis section provides instructions for properly cutting shafts and installing components. Arrow maintenance procedures are also included.

PRELIMINARY BOW SETUP
The first phase in achieving well tuned equipment is good preliminary equipment setup. If the initial setup is done correctly, bow tuning can be an easy process. By following the bow setup guidelines in the initial preparation of yourequipment, you can eliminate most or all of the possible disturbances which cause tuning problems, including false tuning indicators. A false tuning indicator would be having a high nocking point indication when the problem is actually poor clearance.

INTRODUCTION TO TUNING
Successful tuning can only be achieved by using a properlyspined arrow shaft. Initially, it is best to start with a shaft recommended by one of Easton's Arrow Shaft Selection Charts or by one of Easton's computer selection programs, the Arrow Flight Simulator or Shaft Selector “Plus.” Final verification is achieved during the tuning process. Any problems due to an improperly spined shaft will become evident during tuning. Before tuning be sure that shaftsare straight, are properly fletched, and have perfectly aligned nocks (see pages 15 thru 30).

Install the Nocking Point
Install a moveable nocking point on the bowstring. Clamp-on types are ideal. Initially, position the nocking point on the bowstring about 1/2" (1.3 cm) above square for RF and CF and approximately 1/4" above square (0.63 cm) for CR. See Fig. 1.
