Yes, it comes off very easily. Just your quiver comed off, the sidewinder stays on your belt. Your existing quiver bracket slides onto the sidewinder and then is held on by a tension adjustment. You existing quiver bracket stays on the sidewinder as well.
i use a custom made quiver mount called "the ground pounder" that holds the arrows inline with the rail of my crossbow....
plus it's high enough to use any kind of sighting tool on my xbow....i leave my quiver on my xbow when hunting, the little extra weights adds to the vibration dampening too....it also stands my xbow on end while i'm standing waiting for deer to come along too..........bob
I use a GroundPounder quiver on my Excalibur, It mounts on the top of the bow and can be easily removed upon arriving at your stand . It doesn't get in the way at all when I have the bow shouldered and it helps with balance.
Sorry bob1961 I see you already posted a pic.
