We love PerfectFlite and what they have done for the hobby.  Due to demand and limited production, PerfectFlite does not sell through dealers at this time.

Please order directly on the PerfectFlight website.  

The 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 interchangeability.
