AltimeterTwo is an instant flight analysis tool for model rocketry, no computer required. It is small enough to fit in most rockets, and it provides 10 key flight performance measures on its sunlight-readable screen for each flight, including max altitude, top speed, engine thrust duration, peak acceleration, ejection timing, and total flight time.
No batteries required. AltimeterTwo is rechargeable and includes a recharging cable that works in common USB ports.
Approved for National Association of Rocketry contests.
Will only work for model rockets.
This will ship in April 2026, when the new version is available.
Ground Station only - features an internal battery, micro-USB interface, and pocket-sized enclosure.
AltimeterOne is a rechargeable digital altimeter with a clear, sunlight-readable LCD display. Its tiny size and rugged construction have helped to propel its use beyond model rockets and planes to kites, quadcopters, falconry, and other sports and activities.

The APRA is an entry-level altimeter that doesn’t compromise on accuracy and capability despite its low price. It is small, easy to use, and audibly reports your rocket's peak altitude and maximum velocity after flight via a sequence of beeps. A post-flight warbling siren sound makes finding small rockets in tall grass easier.
Note: this is a preorder and will be shipped when the manufacturer resumes production.
TeleMini is a recording dual-deploy altimeter for model rocketry with telemetry link.
Please note that this board requires a 1S LiPo battery with appropriate JST connector for operation. To ensure proper voltage and polarity, and to avoid unexpected resets during pyro events, we strongly suggest you buy an Altus Metrum battery for use with TeleMini!
The currently shipping version is TeleMini v3.0.
The Blue Jay 2 altimeter is the easiest rocketry altimeter to install and use.
