The Student Harness - Sigma TANDEM VECTOR Owner's Manual

SIGMA TANDEM SYSTEM OWNER'S MANUAL

THE STUDENT HARNESS

The Sigma / Vector Student Harness is quite a departure from previous tandem student harnesses. It was designed,
with the help of a cardiologist, to safely contain the human body without cutting off normal blood flow. Disrupted
blood flow is why almost all students on older student harnesses were uncomfortable, and why some got sick or even
passed out.
A hip-hugging horizontal back and belt strap combination allows the main lift webs to be positioned, and held, more
toward the front of the upper body than on other designs. This prevents the "squeezing" of the upper body and the
inside of the upper legs which can cut off blood flow. It also automatically lifts the legs up and forward after opening,
putting them in a safer position for landing.
The Student Harness was designed to comfortably and safely fit a wide range of body sizes and types. To accomplish
this, it has thirteen (13) points of adjustment. This wide range of adjustment means that it is possible to give a
tandem student a truly comfortable experience on their tandem skydive. However, the harness must still be adjusted
securely to fit the student's body to prevent them from falling out in extreme situations and unusual body positions.
While fitting this harness on a tandem student is not difficult, it is different from other harnesses you may have used
in the past. The most important point to consider is the security of the student. You must insure that all straps are
comfortably snug against the student's body.
