The redesigned Backpacker UL gives the user more versatility and options. The new center column makes getting setup to glass a breeze - but is easily swapped out to the included 3.25" short column. In either configuration, the unique hollow-ball eliminates the limitations of a vertically locked-in center column. A half-turn on the central locking lever gives the versatility of a leveling head for shooting, without sacrificing stability. The tripod is configurable with any of our tripod heads, purchased separately.
