Before Bill Booth’s invention, the industry relied on the Capewell system, which was originally designed for ground use, required a complex two-step process, was difficult to use, and occasionally led to fatal malfunctions.
The first customer to receive the 3 ring release system was Dennis Sattler WonderHog SN# 294. Quickly EVERYONE wanted the 3 ring!
➡️The Three-Ring System: Invented by Bill Booth in 1979, this device allows a skydiver to jettison a main canopy using a single handle.
➡️Mechanical Advantage: The system uses rings to multiply mechanical force, allowing the yellow release cable to be pulled with less than five pounds of pressure, despite the forces exerted by the parachute and the jumper’s weight.
