The STUBBY was designed specifically for bows that have a second lower threaded stabilizer port like the Hoyt Ventum.This is an extremely effective filming option for hunters to gather more information on their shot placement before going into a blood trail. Our mount utilizes rare earth magnets to allow any cell phone to instantly attach to any bow to help you recover more game! Being able to review your encounters and share hunts with others has never been easier. This affordable filming method yields very impressive footage when properly setup using our foam dampening system. A strip of one sided adhesive foam is included in every kit to help reduce vibration realized in your video.
