The new Estes 2013 catalog features an altimeter unit on the back cover.
There has been some speculation about the unit and it's features.
I have been provided one of these unit to fly and test out.
The Estes Altimeter features a four-digit LCD readout, replaceable battery, anchor point, memory storage for up to ten flights and displays peak altitude in feet or meters (Max altitude is 10,000 feet or 3000 meters).
There is a seperate power switch and function button.
The unit has an overall length of 2 3/8", if the anchor flange is not included the length is 1 13/16" (44mm). The diameter is almost 18mm, a tight fit in BT-20 tubing but Centuri/Semroc ST-8 size tube should work fine. Weight is 14grams. Operating temperature is 41-100 degrees F.
I have flown the altimeter a several times and it's readings are within 2% of those recorded from 'other' altimeter units flown in the same rocket/motor combination.
The availablilty of Estes products in hobby shops and with a SRP of around $30-$35 should see many rocketeers flying these altimeters. :)
