The 685B Neotec Monopod Deluxe replaces the 684B and includes four new features.The 685B sports a new safety lever that prevents accidental deployment of the locking release mechanism. To close the monopod, simply activate the safety lever with the small 'pinkie' finger, which then allows the grip action handle to be depressed. The lever is simple to operate while still maintaining the one-handed closing operation.To further improve the single-handed performance of the Neotec Monopod, Manfrotto has added a lightweight rubber foot pedal to make opening or closing a snap. To increase the height of the camera, simply step on the pedal and lift the monopod to the new position. For storage and transportation, the foot pedal folds away against the bottom leg section.Manfrotto has also added a protective leg-warmer on the bottom leg section to provide protection against the elements and offer a comfortable grip during transportation. And for extra ground support and increased grip, a suction cup foot has been added.All these features add up to Manfrotto's most advanced monopod, while maintaining the extremely powerful Neotec clocking system to withhold the heaviest of camera systems making it the ideal tool for the extreme sports photographer to the advanced amateur.Features:Special aluminum alloy used in the aeronautical industry.Combines the same leg release technology developed for the 458B Neotec Tripod and the design concept of the 3245 Automatic Monopod.Monopod head attachment using the dual 1/4" and 3/8" fixing screw.Wrist carrying strap included.
