This versatile, easy to use altimeter audibly reports your rocket's peak altitude and maximum velocity after flight via a sequence of beeps. Two outputs are provided for deploying a small chute at apogee to minimize drift and a larger chute closer to the ground to slow your rocket for a gentle touchdown. Main chute deployment altitude is adjustable from 30m (100 feet) to 3,050m (9,999 feet) in 30mm (1 foot) increments with the computer interface or 30m (100 foot) increments without. Nine user-defined presets make changing the settings in the field quick and easy.

The StratoLogger collects flight data (altitude, temperature, and battery voltage) at a rate of 20 samples per second throughout the flight and stores them for later download to a computer. It retains data from the most recent 31 flights (up to 9 minutes per flight) even with power removed. The optional DT3U data transfer kit includes software for graphing and printing a wide range of characteristics including altitude, velocity, and more.

The StratoLogger is capable of recording flights of up to 30,480 m (100,000 foot) altitude (well into the stratosphere) with industry-leading precision and accuracy.

Works to 30,480 m MSL, and audibly reports peak altitude and maximum velocity after flight.

Stores 31 flights of 9 minutes each (altitude, temp­erature, and battery voltage at 20 samples per second) for download to a computer with the optional DT3U USB interface. Data is preserved with power off.

Deploys drogue and main chutes with audible ematch continuity check.

Outputs capable of 10A current for 1 full second to allow use with nearly any ematch or ematch substitute. Reverse polarity protection prevents spontaneous firing if battery is connected backwards.

Measures just 50mm (2.0") L x 21mm (0.84") W x 12.5mm (0.5")H, fits 24mm tube, weighs just 11g (0.38 oz)
