In Florida we are not allowed to screw anything into a tree so, like muzzyman88, I use a Fosters Deluxe bowholder attached to the bottom of my Summit Viper climber. It works very well for me and beats the hell out of holding the bow in my lap or balancing it between my legs like I did before. Only thing with any kind or bow holder though is to make sure that it is screwed in tight. My stand mounted holder has a screw that allows you to change the angle that the bow is at by loosening and tightening a handle. That causes the bow mount to pivot around. Although it has not happened, it is possible to envision the mount pivoting so that it would dump the bow out. Same thing with a treemounted swivel that is not screwed in all the way. Last thing you want to see is you bow tumbling 25 feet to the ground.
