CPR Based Kits 

What is CPR? CPR is an altimeter based, two-step parachute deployment system. Using a dual-deployment altimeter, the first chute (a small drogue) is deployed at apogee allowing for a fast but controlled descent. At approximately 400/800 feet, (user selectable) the altimeter fires a second charge deploying the main chute allowing for a soft landing.

The altimeter is centrally located in a special compartment within the main airframe. The drogue chute is ejected from a split-point in the airframe just above the fin/motor section while the main is ejected at the nose cone. Both chutes are deployed using Public Missiles' exclusive Piston Ejection System.
