|This gauge is suitable for use on sport aircraft but is not certified for use on certificated aircraft- This unit does not require an extemal shunt. It is constructed with a heavy duty, "air-core" mechanism. Unlike other commonly found gauges, this gauge has no moving parts except the needle which is moved by opposing electro-magnetic force. The advantages of this design are many. The needle is stable and true, even when subjected to vibration. The gauge is immune to shock and therefore needs no special shock mounting system. This gauge withstood a design test of over 100 G-Force with continued operation.|
