Since its introduction in the mid 80's, the Autoscope has been the choice borescope inspection tool of aircraft engine manufacturers Teledyne Continental and Textron-Lycoming. It's an easy to use, portable, inexpensive, battery powered side viewing borescope that is optimized for viewing cylinder walls, and engine valve areas. The complete Autoscope kit includes the borescope, a heavy-duty battery handle with a 6 foot cord, and a plastic case. The Autoscope is recommended by Continental to perform the borescope inspection phase of their SB03-3 Service Bulletin. 8 lbs (4Kg) shipping weight.
