Good morning Richard, My Raven altimeter is armed and disarmed by a magnet. I've armed it in my Fatman, but that rocket had a hatch door set for the electronics. Not quite a AV-BAY setup. How big of a rocket are you working with. I've toyed with it outside of a rocket. I used a COW Magnet. The magnet is about 3/4 inch dia. And 3 in. Long it would arm and disarm from 10 inches away.
