Zeiss MAX-DUTY V Tripod KitThe Zeiss MAX DUTY V Tripod Kit includes the Zeiss MAX DUTY Tripod, the Ballhead V 60, and accessories. The MAX DUTY legs are 10 layer heavy duty carbon fiber woven in a matrix pattern for maximum rigidity. They consist of 3 tubes with diameters of 36, 40, and 44mm. The largest leg tube is closest to the ground making it easier to adjust leg extension and reduces the chance of dirt getting onto the lowest leg locks. The V in the name of the V 60
