PET2+ Programmable Event Timer
The PET2+ sets a new performance standard with the most advanced and versatile dual event timer functions available in High Power Rocketry today. It's the perfect choice for staging, airstarts, or other specialized timing applications from the simplest to the most complex projects.
The PET2+ goes beyond "dumb timer" capabilities, by providing programmable G-ranges and integration timing so you can discriminate chuff's or cato's from actual "motor ignition" events. Couple these capabilities with its 3-axis orientation and you get the most "mission adaptable" timer for HPR.
