Powerful 3.5" diameter digital motor runs cooler and lasts longer. Intuitive push/pull, forward and reverse speed adjustments. BluVis integrated speed and battery indicator. Taper-Lock mount with 7-point adjustment eliminates slack. One-touch, rapid slide-depth adjustment collar. Extending Tri-Lobe, soft-touch handle for the perfect feel and control.
