The Gen3 MagVibe immediately turns concrete floats into vibrating floats. It utilizes high frequency vibration at the float, not at the handle, to increase productivity and minimize fatigue. It has 3 speeds for optimal vibration control, is water resistant and can operate up to 20-hours on a single charge. It bolts onto traditional floats with the QAS quick attach system and has tool-less innovation for easy removal. Built-in 24-Volt Lithium-Ion Battery included. Material: Aluminum.
