Using a "Tri-Titanium" aerospace alloy compromised of aluminum, magnesium, and titanium, the Slik 700DX Pro Tripod Legs has a strength-to-weight ratio 40% greater than comparable tripods in its class. It is a very professional unit whether you"re concerned with strength, fit and finish, or refinement of operation. The rapid-type center column cannot rotate accidentally, and the lever locks work securely with a minimum of movement. The 700DX has foam-padded upper segments to ease carrying on your shoulder and working in the cold, and its simple angled rubber leg tips give a firm footing while also allowing you to carry it upon some aircraft.
