The Bogen/Manfrotto 540BB Video Carrying Bucket Backpack is designed to hold any tripod with any video head still attached. The head is placed in the lower "bucket" where its weight is better supported and less likely to swing off balance and hurt you, the legs extends up your back and are firmly tied in position. The bucket back pack is especially useful on longer journeys or on wilder terrain, where you still need to know that you can release the tripod, set up and shot in seconds.
For birdwatchers, airplane enthusiasts and other users of spotting scopes, the bucket backpack will also let you transport your whole kit, with the spotting scope attached.
