Official altimeter for the Team America Rocketry Challenge.

The Perfectflite FireFly is a tiny, lightweight altimeter that reports the peak altitude and speed of your rocket's flight. Its high accuracy, low price, and ease of use make the FireFly ideal for rocketry education programs where precise, repeatable data is required on a limited budget. Each altimeter is individually calibrated for optimum accuracy, repeatability, and interchangability.








Features:

•Works to 100,000 feet MSL, audibly reports peak altitude and maximum speed after flight.

•Unlike many other low cost altimeters, each unit is individually calibrated and tested for optimum accuracy, repeatability, and interchangeability.

•No mach delay necessary for mach+ flights: Automatic MachLock assures proper operation with any flight.

•Uses common type CR1025 lithium battery(included).

•Low power design – battery lasts for over 30 hours.

•Precision sensor & 24 bit ADC yield superb 0.1% accuracy.

•Highly resistant to false triggering from exposure to sunlight and from wind gusts; tested in 100+ MPH winds!

•Wide operating temperature range of +32F to +185F.

•Measures just 1.1"L x 0.68"W x 0.31"H, fits 18mm BT20 tube, weighs just 0.12 oz. including battery.

•Rugged SMD construction, stringent QC testing, and internal self-diagnostics assure uncompromising reliability.

•Backed by full three year warranty.
