Tiffen Steadicam G-70x Arm

The revolutionary, patented Geo spring geometry optimizes performance throughout its lifting range. It tames high/low arm travel with adjustable-length crankshafts that dynamically rock the spring termination as the arm is boomed up or down. Powered by coaxial titanium spring sets, the G-70x arm smoothly carries any load from 13 to 70 pounds (5.8 to 32 kg).

The design criteria for the G-70x arm: light weight (10.8 lbs / 4.9 kg), user-maintainable, and a 29 inch (73 cm) boom range. It has soft bumpers at each end of travel so the arm can be boomed right to its limits without shot-disturbing clunks. The G-70x also has a Ride control that adjusts the iso-elastic response of the arm.

Two more G-70x innovations: The arm posts are locked in place by a single lever, so switching arm posts is quick and easy. This quick-change mechanism also has an adjustable drag for the post’s rotation, from completely free to totally locked.

At the socket block end of the arm is a new, “kick back” link, which gets the arm further out of the way as the sled crosses the operator’s body, and keeps the arm from banging against the stops in normal operation.

The net result: the smoothest, best performing arm ever built, and all parameters are user adjustable.
