Range 100 metres. royalbcmuseum.bc.ca The mechanical foundation of Atlatl technology is the flexible Dart. Under acceleration by the Atlatl, the Dart flexes and compresses like a spring, storing energy to be used to push itself away from the Atlatl and launching at velocities that easily exceed 100 mph. The first of many improvements to this mechanical system was multiple length atlatls to fine tune the system longer atlatls for increasing range. Interestingly, the number P1 is found for optimum performance in the Relationship between atlatl length and dart length. ***************** The great innovation of atlatl weights in the evolution of this technology bears the mark of true genius. By super imposing flexibility into the atlatls shaft and applying a mass to influence the amount of flexduring the swing, the energy stored in the spring of the atlatl can be exactly matched to that of the dart. This allowed for a more efficient use of available energies by forcing the atlatl to push away at the same time the dart is pushing away from the atlatl, much like a diver pushing away from a springboard platform.
