This unit was pulled from my Cessna 172 because I needed
a serialized output from the encoder to interface to the new GPS.
The unit was working well when removed earlier this year.
It was last bench checked for calibration to 20,000' during an
IFR certification on 7/16/2004 by an approved shop. The stickers
are still on the unit.

A factory new unit from the Gyrohouse sells for $667.50.

The same mode TCI encoder can be found on Ebay used
