The Painted Arrow MAG-PRO X is the ultimate POV camera solution for crossbow hunters. This patent pending product allows crossbow hunters to quickly and easily secure their smartphones to their crossbow using high powered rare earth magnets. The MAG-PRO X mount was designed to fasten onto the tensioning nut of the front scope ring, included within the kit. When purchasing a kit you will select the 1 inch or 30 mm option, which is dependent upon the size of your scope tube. (If you don't know the size of your scope tube, feel free to contact our customer service team.) By simply adhering the metal plate (included in our kit) to the back of your phone case, you are able to quickly and silently attach your phone to your crossbow to film your shots. Filming your hunt has never been easier! This product was designed as a recovery tool to allow hunters to gain as much information as possible when going into a blood trail. #ReliveTheHunt and recover more game!
