The Outdoorsman adapter is built for strength but not ergonomics. As the stud is mounted in the objective lens hinge, this is forward of the center of the binos. This creates a longer radius(center of tripod to bino lens) and greater panning circumference, as compared to the cheaper strap on adapters that allow center of binos to be placed directly over center of tripod. The longer the binos, 12 and 15, the longer the radius. So extended glassing, especially panning, with the Outdoorsman leads to more head and upper body movement. Another disadvantage of the Outdoorsman compared to the strap on type, is the binos have to be spread, to fit over the stud, and then remelded(2 viewing barrels into one)
