Fixed 1.37m extension pole to suit the Infaco Electrocoup F3020 electric pruning shear (this does not suit previous models of Electrocoups). External battery model - simply plug the battery in to the connector on the base using the existing handpiece-battery cable, insert and attach handpiece to the top of the pole and start pruning. Sliding handle/trigger controlled by Bluetooth technology, so no cables between the trigger and handpiece/pole. Battery and handpiece are not included with the pole. Electrocoup part number 9F120.
