JOLLY LOGIC

Jolly Logic Altimeter One

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.

Jolly Logic Altimeter Two

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.

Chute Release is a small electronic device that holds your rocket parachute closed until it drops to an altitude that you choose. This is great for windy days and small fields when normally your rocket would drift too far while descending under parachute.

Simply wrap the elastic around your folded parachute and snap it into the other side of the release, then set the altitude from 100 to 1000 feet (30-300 meters) and you are ready for launch.

The Snap Mount for AltimeterOne, AltimeterTwo, and AltimeterThree.

The Snap Mount makes it easy to mount your altimeter quickly and securely. Made of strong polypropylene, these mounts are built to be tough. Just insert the nose of your altimeter under the clip, then press the other down until it snaps securely. To release, you spread the snaps apart to release the altimeter.

Just slightly wider, longer, and higher than the altimeter itself, and very light (weighs just 4 grams).

Kit includes screws, nuts, and bolts that work on a variety of materials. Also includes hook-and-loop strap that you can trim with scissors to fasten the mount to fuselages, struts, and landing gear.
