B.0 TANDEM RELEASE OPTION
The 8242XS acoustic releases come with an optional Tandem Kit. A Tandem Kit is used to join two releases,
providing a single lift point and single release point. Therefore, two 8242XS units can work together in
tandem. The primary purpose of the Tandem Kit is to add redundancy to the mooring, thereby increasing
the odds of instrument recovery.
When a Tandem is used with a mooring it can be recovered by releasing the 8242XS Release. In the event
of a failure of the mooring to detach from the anchor, the RELEASE command can be sent to both 8242XS’s
freeing both the oblong ring and chain assembly. In normal use, when just one release is triggered the
only thing that is lost is the oblong ring.
