The Eberlestock Butt Bucket is a must have accessory for the active hunter.  The ability to carry your bow on your back leaves your hands free to hike, climb, glass etc. and then be able to get your bow off quickly without taking off the backpack is awesome.  I use a butt bucket every single time I go out hunting, whether I am hiking in 5 miles or 1/2 mile it just adds a lot of convenience.  Check out the video I did below on how to properly mount the butt bucket.
