The redesigned Backpacker UL gives the user more versatility and options, at a better price point, than its predecessor. 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 the Revic tripod heads, purchased separately. Multi-Layered Carbon Fiber 0.86 Max Tube Diameter 4 section 15.25 Folded Length 43&quot Mfg: Revic Optics
