The FireFly is a tiny, light-weight altimeter that reports your rocket’s peak altitude
& speed through a series of blinks. When used with the optional Field Data Display,
it also reports time to apogee, total flight time, and descent rate. The high accuracy,
low price, and simple operation make the FireFly ideal for rocketry education programs
requiring precise, repeatable data even within the constraints of limited school
budgets.
