I feel that this technique reduces experimental error. The results of the two methods seldom differ by more than 1 foot per second. In this instance, the values are identical at 246.6 fps. The Fury displays outstanding performance. Obviously, I cannot test all the high-performance bows that are available, but this is the highest rating velocity I have found for the bows that I have tested to date.
Kinetic energy is the energy possessed by a mass in motion.
The initial kinetic energy of an arrow is calculated from the mass of the arrow and its velocity as it passes through the chronograph. Figure 3 presents curves of initial kinetic energy plotted versus arrow weight for the three levels of peak draw force tested. With the slider furnished, one that carried the cables on the outside of the guard rod, I felt that, as the tests progressed, the string was coming uncomfortably close to the rod during the launch. At 30 inches draw length, the included angle of the bowstring measured 88 degrees. I shot the Fury by hand, using only finger release.
