The Jolly Logic Altimeter analyzes flight altitude, acceleration, top speed, flight duration, and six other important flight statistics.

• Rechargeable
• No Computer Required
• Altimeter Provides Flight Altitude, Top Speed, and More
• Ten Key Rocket Flight Statistics
• For Model Rockets Only

AltimeterOne can be used for anything that flies, but it tells you only the peak altitude. AltimeterTwo is just for rockets, but it provides all 10 key rocket flight statistics.

Neither requires a computer, and both are rechargeable.
