If your equipment is set up differently, follow instruction below to
determine your Calculated Peak Bow Weight before using this chart.

Using the Easton Target / Field / 3-D Shaft Size Selection Chart

Once you have determined your Correct Arrow Length and your Actual or Calculated Peak Bow Weight, you are ready to select you correct shaft size:
1. In the "Bow Weight" area on the right or left-hand sides of the CHART, select the column that best describes the type of bow you shoot.
2. Move down the column to locate the box that includes your Actual or Calculated Peak Bow Weight.
3. Move across the row in a horizontal direction until you locate the column indicating your Correct Arrow Length. One or more recommended sizes are listed in the "Shaft Size" box located where your Actual or Calculated Peak Bow Weight row and Correct Arrow Length column intersect.
4. Depending on your shooting requirements, choose a shaft from the various types and weights of shafts listed in the box.

Reading the Easton Target/Field/3-D Shaft Size Selection Chart

The chart indicates that more than one shaft size may shoot well from your bow. Shaft size in bold type are the most widely used aluminum sizes, but you may decide to shoot a lighter shaft for speed, or a heavier shaft for greater durability. Also, large variations in bow efficiency, type of wheels or cams, bow length, string material, and release type may require special bow tuning or a shaft size change to accommodate these variations.

"Shaft Size" Column - indicates suggested shaft sizes.
Alternate size choices are shown in parentheses for some shafts. A/C/E shafts perform differently in recurve and compound bows. The A/C/E size recommendations for recurve bows are indicated with a letter "R" next to the size. To determine the recommended sizes for compound bows (with finger release), add 10-15# to your Peak Bow Weight (use shafts 2-3 sizes stiffer). For compound bows using release aids, add 5# to your Peak Bow Weight (use shafts 1 size stiffer).

"Shaft Model" column - designates arrow model.
"S" =XX78® Super Slam® shafts. Also Camo Extreme™ shafts in sizes 2213, 2314, and 2514, (7178 alloy)
"75" = E75® and all XX75® model shafts - Autumn Orange®, Easton Classic™, Advantage™, Camo Hunter®, GameGetter® II and GameGetter® (7075 alloy)
"X7" = X7® Eclipse® shafts (7178 alloy)
"E" = Eagle® Target shafts (5086 alloy)
"A/C/E®" = Aluminum/Carbon/Extreme shafts
"A/C/C®" = Aluminum/Carbon/Competition shafts
"P/C" = Pure/Carbon shafts

"Shaft Weight" column - indicates shaft weight only.
To determine total arrow weight, add the weights of the shaft, point, insert (or outsert), nock and fletching. Aluminum shaft weights listed are XX75 weight unless the shaft is produced only in X7 alloy. Letter codes A-C listed to the right of shaft weight indicate the relitive stiffness of each aluminum shaft within that "Shaft Size" box ("A" being the stiffest, "B" less stiff, etc.).

Using A/C/E Shafts With Compunds
To determine the recommended A/C/E shaft sizes for compound bows with finger release, add 10-15# to your Peak Bow Weight (use shafts 2-3 sizes stiffer). For Compound Bows using release aids, add 5# to your Peak Bow Weight ( use shafts 1 size stiffer).

*The 2214 X7 closely matches the 2215 XX75 and will shoot very nearly the same from your bow. The 2214 is only 7 grain lighter in weight and .010" weaker in spine @ 29" than the 2215 XX75.

Although Easton has attempted to consider most variations of equipment, there are other style and equipment variables that could require shaft sizes other than the ones suggested. In these cases, you'll need to experiment and use stiffer or weaker spine shafts to fit your situation.

Determining Correct Arrow Length
For target/field archers, the Correct Arrow Length for any type bow (including bows equipped with overdraws) is determined by drawing back an extra long arrow and having soeone mark the arrow as shown.

Determining Actual Peak Bow Weight
Actual Peak Bow Weight for recurve bows (measured at your draw length) and compound bows can be determined at your archery pro shop.

Determining Calculated Peak Bow Weight
The "standard" setup used to determine the suggested shft sizes is listed in the upper right corner of the CHART. If your setup differs from the standard, use the Variables listed below to make adjustments. Add or subtract the appropriate amounts to calculate the effective Peak Bow Weight of your bow. Use this Calculated Peak Bow Weight to select your correct arrow size on the CHART.

Variables to the "Standard" Setup:
• Finger release (compound bow) - Add 5-7 lbs.
• Dacron string - Subtract 3-5 lbs.
• Compound bow lengths less than 43" and drawn over 28" - Add 4-6 lbs.
• Point weight - Add 1.5 lbs. For every 10 grains your point weighs more than the recommended point weight. (Subtract if point weight is less.)
• 7% F.O.C. point, Standard, Lite, SuperLite aluminum shafts
• 8% F.O.C. point, UltraLite aluminum shaft
• Recommended point weight, P/C and Specter shafts
• Medium Weight Points, A/C/C shafts
• Recommended insert + point weight, or One-piece Point weight, A/C/E shafts

Overdraw bows
If you are using an overdraw, make the above calculations (if any), and then multiply the Calculated Peak Bow Weight of your bow by the appropriate factor listed below.

For 60#-70# Actual or Calculated
Peak Bow Weight, add to bow
weight-(or use factor below)
For any bow weight, multiply you
Actual or Calculated Peak Bow
Weight by the factor to the right
