SIGMA TANDEM SYSTEM OWNER’S MANUAL<br />
SELECTING THE PROPER<br />
STOW BANDS<br />
Band types for:<br />
1) All Dacron lined canopies<br />
2) Microline<br />
NOTE: If you run out of all specialized Tandem<br />
rubber bands (2” x 3/4”), it is possible to use<br />
two regular rubber bands for each line stow.<br />
Be sure the combined width of the two rubber<br />
bands does not exceed 3/4 inch in width. Any<br />
substandard bands should be replaced with<br />
Tandem bands as soon as possible.<br />
TANDEM TUBE STOWS<br />
LINE DUMP<br />
Definition: During bag lift-off, the rapid<br />
acceleration of the main bag can cause the<br />
entire line stow group to fall off the bag due<br />
to loose or weak stow bands.<br />
The stow bands used on the Tandem Sigma<br />
are very important. Even more so than sport<br />
rigs, as the Tandem main bag is lifted out of<br />
the container at a more rapid rate. The<br />
Tandem Sigma must have the suspension<br />
lines securely stowed. Be cautious of bands<br />
which are too weak or stretch too much as<br />
they can cause deployment problems.<br />
Because of the increased weights involved in<br />
carrying two people, the forces on the bag at<br />
deployment time can be enough to cause line<br />
dump if the bands are not tight enough. On<br />
the other hand bands that are too tight may<br />
cause problems disrupting the even<br />
sequencing of the deployment.<br />
Line dump can lead to partial malfunctions as<br />
the loose suspension lines quickly come<br />
under tension, and will at times form pressure<br />
knots, causing lines to entangle.<br />
