A New Collins' Lanyard (Patent #6,056,242); A New Student Harness; Exterior Veiwing Windows For The Reserve Pin And Cypres; Summarizing The Advantages Of The Sigma Tandem - Sigma TANDEM VECTOR Owner's Manual

The Sigma Tandem now integrates our proven "Collin's Lanyard" System into the yoke for a totally hidden installation.
This system automatically releases the other main riser if the RSL-side main riser breaks, or releases
prematurely for any reason. This prevents a potentially fatal main/reserve entanglement. You can only get this
important safety system on a Vector.
Both the Tandem instructor and student harnesses feature our exclusive ½ " thick "Wonderfoam" padding for a more
comfortable canopy ride.
The New Sigma student harness is designed to be far more comfortable, while at the same time offering more control
on exit, and forcing the student's legs forward and upward under canopy. This means fewer students will get sick or
pass out under canopy. It also means fewer landing injuries, a greater return and progression rate, and a better
review of their tandem jump to friends, which in turn means more, and happier students.
EXTERIOR VIEWING WINDOWS FOR THE RESERVE PIN AND
Now you can view your reserve locking pin, and turn your Cypres on and off through clear windows, without opening
your reserve pin cover flap. The reserve pin window is made of Lexan, and simply slides into place for easy replacement
if it becomes badly scratched. The Cypres window is just above the reserve pin cover flap, so a pin check, and Cypres
condition check can be accomplished at a glance, even while you are wearing the rig.
SYSTEMS BORROWED FROM THE VECTOR III SOLO RIG
Sigma Tandem Systems also share many features with our Vector III solo systems. Riser covers, and both main and
reserve pin cover flaps, incorporate tuck-tabs instead of Velcro. The main container side flaps wrap around the
bottom of the container to provide positive bridle protection. These systems set the industry standards for superior
pin and main bridle protection, as proven by years of field-testing and use.

SUMMARIZING THE ADVANTAGES OF THE SIGMA TANDEM

1 . It takes fewer steps, with fewer potential errors, to close the main container.
2 . Accidentally snagging the drogue bridle will not open the container.
3 . Out-of-sequence deployments are eliminated.
4 . Its center-of-main-container drogue connection gives a more "natural" and comfortable drogue-fall position than
other Tandem systems.
5 . The drogue release ripcords are automatically retracted after use, or accidental snagging, so that they are always
where they should be, cannot be lost, and don't have to be stowed after pulling.
6 . It has two redundant, fail-safe drogue release ripcords, one on the right, and one on the left.
