UPT Sigma Tandem Skydiving Container with Passenger Harness. United Parachute Technologies is the king of the skydiving industry.

UPT with Bill Booth at the helm is known for the 3-ring system, tandem skydiving, magnets, spectra reserve ripcord and the Skyhook. 

In engineering, the word Sigma means a "Summation" or "Answer" to the problem. UPT chose to name their tandem rig Sigma, because it represents a "Summation" of everything they have learned about tandem equipment, and the people who use it, since 1984.

Unlike all other tandem systems, where the drogue was simply tacked onto an existing design, the Sigma was built from the ground up, as a drogue deployed system. Contained within its design is an "answer" to every container related problem UPT has observed.

Unique highlights and features of the Sigma Tandem System include:

  • Comfortable Head High Position
  • Patented Disc Release Handles
  • Retractable Release Handles
  • Superior Pin Protection
  • User-friendly Component Replacement

Sigma Advantage: The Parts

A special safety pin prevents premature container openings if release handles are accidentally pulled prior to drogue deployment. This pin is automatically extracted once the drogue is deployed, thus arming the drogue release handles

A diagram on the inside main pin flap makes it easy for anyone to do a pin check while inspecting the new disc drogue release.

Magnetic Riser Covers

Super clean design of the new drogue pouch eliminates the need for velcro or tuck tabs. Packing is quicker and trouble free.

Drogue

The drogue bridle is completely covered. But even if you accidentally snag the drogue bridle, it will not open the main container.

Both left & right handles for drogue release.

Both drogue release handles are retractable. Pull either one, pull both simultaneously, and let them go. They'll retract right back to their original position.

The right drogue release handle is conveniently positioned on the upper right leg strap to simulate a BOC deployment for the student. Its permanent position eliminates the worry of relocating it on each jump, or the possibility of being accidentally dislodged.

Skyhook RSL

The Automatic Release Lanyard is now incorporated into the RSL. If the RSL side riser breaks, or releases by itself for any reason, this feature will automatically release the other riser, thus preventing a main-reserve entanglement.

The RSL, with its Tru-Lok pin, is designed so that only a hard, straight-up pull will cause a left side cutaway and reserve activation, greatly reducing the chance of accidental functioning..

UPT believes that you should be able to activate your reserve with either hand. So the RSL is designed to also function as a right hand reserve ripcord, in the event that the standard left hand reserve ripcord cannot be reached, because of injury or student interference.

Disc Release: How It Works

Note: Some photos are shown without disc covers however all discs come with a disc cover now.

The drogue is connected at the center of the main container, and held in place by the main container closing system.

This yields a head high droguefall position, and makes our of sequence deployments virtually impossible.

When either ripcord is pulled, the closing loop slips through a series of "D" rings, allowing the container to open and release the drogue disc. The drogue then partially collapses to the size of a normal pilot chute, and deploys the main canopy.

Because the normal loop-through-grommet main container closing system also holds and releases the drogue, this is no need for the addition of a three-ring drogue release. The system is far less complex and therefore much more reliable.

The Sigma can hold the following parachutes. Main Canopy: Sigma 370, Sigma 395. EZ-384, EZ-425. Reserve Canopy: VR-360.
