This unit is completely mechanical in action, not dependent upon batteries, squibs or pyrotechnic devices. It’s both compact and rugged in order to withstand the service normally found in parachuting. It can be used on the main or reserve parachute. The function is to withdraw the ripcord pin (main or reserve) in the event the parachutist reaches a preset altitude with a rate of descent exceeding 65 feet per second. Under normal conditions the unit does not operate.
OPERATION: The altitude control may be set from 1,000 to 4,000 feet above ground level. Ground level may be anywhere from sea level to 10,000 feet elevation. While on the ground simply set the altitude indicator at the point you want your parachute to open in case of emergency. Knowledge of field elevation or barometric pressure is not required. Then when you are ready to jump, simply turn the safety lockout from OFF to JUMP position.
Unit comes with User Manual, (C) Bracket, (D) Screws, (G)Mounting Plate, (K-L) Large Hotel Terminal Pin or (K-S) Small Hole Terminal Pin
