AltimeterTwo - digital altimeter reports 10 data points

The AltimeterTwo is a rechargeable digital altimeter (for model & water rockets only) that analyzes flight altitude, acceleration, top speed, flight duration and 6 other important flight statistics. The AltimeterTwo retains the rugged design, easily-readable LCD, small size, and rechargeability of the AltimeterOne. With the addition of a 3-axis accelerometer and a 4X speed increase in processing speed, it can provide a full suite of important flight statistics that can help you analyze and improve your rocket's performance.

As of March 2012, the Jolly Logic AltimeterTwo has been approved by the National Association of Rocketry for use in rocketry competitions. AltimeterTwo User Guide
