Details: In engineering, the word
Sigma means a "Summation" or "Answer" to the problem. We chose to name
our new tandem rig Sigma, because it represents a "Summation" of
everything we 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 we have observed.
