RSL vs Skyhook RSL
While a normal RSL 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.
