Dual Deployment, in general terms, means that two parachutes are ejected out of the rocket. The first parachute is a small one (often called a drogue chute), and is ejected at apogee. As the rocket descents, a secondary ejection charge is fired (typically between 500 and 700 feet) and a full size parachute is ejected, bringing the rocket down to a much lower descent rate that will not damage the rocket upon hitting the ground. The advantage is that the rocket falls fast for most of the descent and doesn't drift very far. It is also called "close-to-the-pad" or "close-proximity" recovery.

In most SSI L2 cert rockets, the avionics bay is riveted to the bottom half of the upper airframe. It acts as the coupler between the upper and lower airframes, with a either a friction fit or shear pins. The rocket separates in two (but is still connected by a shock cord) at apogee, deploying the drogue. The main chute is deployed from the top of the upper airframe, pushing out the nosecone with it, similar to an L1 ejection.
