United States EASTON arrows are often used by personal and team archery. But the starters have great difficulty to choose the arrows. Now here goes a simple description of the aluminum alloy arrows.


United States EASTON aluminum arrows` different models shows by four digits. We start explaining with the 4 numbers. The first two numbers shows the outer diameter(algorithm is divided by 64 and multiplied by 25.4 unit millimeters). The last two numbers shows the thickness(divided by 1000 multiplied by 25.4 unit millimeters).  For example, 1814 aluminum alloy arrows` outside diameter is 18/64x25.4=7.14mm, thickness is 14/1000x25.4=0.355mm.

Current commonly used aluminum alloy arrows shot types and parameters are as following:

Select Arrow Length is to select the length of the arrow in this software. The length of the arrow should be calculated by one`s pull distance, such as: if the armspan is 180, the pull distance is 180/2.5 =72cm28.3inch according to the formula, actually an arrow with 76-80cm that is 29-30inch length is needed.
