Had a chance to fly a few test flights today with Jolly Logic's new Altimeter 2. I bought mine at Commonwealth Displays. Absolutely fantastic altimeter. Brain dead simple to use, tons of useful data, great consistency of data recorded with same rocket, same motor, on multiple flights.

Rugged little bugger, too. Flew it in an Estes X-ray which separated at 230 feet and nosecone came in ballistic. Altimeter pushed up into the nosecone and had to be pried out, but the altimeter was fine. Okay, to be honest, the X-ray parted on two different flights, and the Altimeter 2 had to be pried out twice. Not a scratch on it and it works fine.

Great little altimeter.

Kudos to Jolly Logic!
