The Blue Jay2 is the new and improved version of the Blue Jay!
The Blue Jay2 altimeter is the easiest rocketry altimeter to install and use. With its built-in magnetic switch, just connect a battery and your e-matches and you are ready to take your rocket to the pad. Turn the altimeter on with the included magnet and the Featherweight UI phone app connects over Bluetooth to show you everything you need to know that the rocket is ready to fly.
Includes standard magnet and mounting hardware.
