The Painted Arrow™ MAG-PRO ARM is the preferred self-filming tool for mobile hunters looking for a do it all, ultra-lightweight, cell phone mount. This durable magnetic cell phone mount is highly adjustable and is extremely adaptable to any situation. The crab claw grip spreads open 2 inches and will clamp to anything you put between its grasp. The arm has 3 pivoting joints that are tightened and loosened by a single tensioning knob located in the center of the mount to allow any angle to be captured.
