A long time in the making, Mirage Systems in DeLand, Florida have finally released their version of a Main-Assisted Reserve Deployment system – or “MARD”. Most readers are likely familiar with the UPT Skyhook. MARD systems build on the concept of a Reserve Static Line (RSL), using the cutaway main canopy and its components as an aid to open the reserve container – but taking it a step further by using the cutaway to extract the reserve canopy. This can greatly reduce the time (and altitude) that it takes the reserve to fully deploy.

MIRAGE’S TRAP SYSTEM® (RSL Mard):
The Trap System® is unlike any other MARD system on the market. It’s a totally different approach. The Trap System® is not attached to the reserve in any way, until you cutaway and the RSL is used. It’s a true ‘non-interference’ system. Since there is no connection between the RSL and your reserve bridle, this means that there is nothing that must disconnect for a normal reserve deployment. If you pull the ripcord, or your AAD fires, the reserve pilot chute and bridle will deploy your reserve quickly and reliably, without hesitation and without interference from the Trap System. Until you cutaway you, and your reserve, won’t know it’s there! Only when you cutaway, does the Trap System® RSL engage to trap and withdraw the reserve bridle, turning your main canopy into a very large pilot chute.
