HAB Bounder


HAB Bounder™ is a self-contained balloon termination, or cut-down, device with an external trigger. It can be configured via a text file on a micro-SD card to activate on a variety of triggers. These triggers include:

  • Mission Elapsed Time
  • Minimum Atmospheric Pressure
  • Pressure Ascent Rate
  • GPS Ascent Rate
  • GPS Altitude
  • Geo-fences


It will also accept an initiating signal from a flight computer, satellite modem, or radio link. Once the command is received, HAB Bounder™ will initiate its independent activation sequence to ensure the line it is attached to is completely and rapidly severed.


HAB Bounder™, formerly the Balloon Bounder, contains the following four common balloon devices:

  • Pre-programmable cut-down device that can sever a line during the balloon flight. If two are used, then redundant flight termination is assured.
  • Flight computer that monitors and records pressure and temperature during the flight.
  • High-altitude GPS tracker that logs position data in both CSV and KML formats.
  • Thermal management device that maintains a minimum temperature to ensure proper operation throughout the flight.


HAB Bounder helps ensure that your balloon flights end predictably and at the appropriate time. Some common uses for HAB Bounder are to:

  • Ensure that your payload stays in a certain geographic region
  • Meet flight safety requirements
  • Cut-away a lift balloon to enable float conditions on tandem balloon flights
  • Avoid lost payloads on single balloon flights that float
  • Cleanly separate your payload from the balloon for glider controlled recoveries


HAB Bounder ships with a protective foam enclosure and micro-SD card. Batteries and rigging line are not included.
