For your JAVELIN ODYSSEY container you can choose an RSL or a SKYHOOK as an option. Both are systems that assure a reserve deployment after cutting away from a partial malfunction.
Generally speaking, the SKYHOOK deploys the reserve significantly faster as the partially deployed main canopy that is cut away pulls the reserve out of the container.
While a normal RSL (standard feature on the Javelin Odyssey) automatically pulls the reserve ripcord pin following a breakaway, the new UPT Skyhook RSL goes two steps further. It automatically releases the non-RSL riser in case the RSL riser was released prematurely (ensuring your reserve will not deploy with half your main still attached). The Skyhook then uses your departing malfunctioned main canopy as a super pilot chute to deploy your reserve canopy, taking about ½ second from breakaway to line stretch (reserve canopy out of the bag). This is 3 to 4 times faster than a pilot chute can do alone. The Skyhook also causes the reserve bag to leave your back with such speed that it becomes far less likely you will entangle with your main canopy in the case of a spinning malfunction.
The RSL will also deploy the reserve after a cut away of a malfunctioning and partly deployed main canopy. In this case the main canopy will pull the reserve pin with the result of normal reserve deployment sequence.
Both systems deploy the reserve after cutting away a partial malfunction, even if the skydiver (out of which ever reason) is not pulling the reserve handle himself.
