The model has eight "barrels", pre-loaded with 100mm x 3mm bands under tension. When the trigger is pulled, the barrel drum revolves one complete revolution, and as each barrel passes the top centre point, its band is released. With new bands, range is over 20'. If the first band misses its target, seven more follow in quick succession!
Powered by a concealed motor, with disengagement clutch to allow drum to be hand-reversed for reloading.
Builder's comment: Never a dull moment when this model is around.
