25 to 40+mm Medium Gun Video Borescope System

Medium Gun Video Borescope System shown with Camera Head Module with centering rings attached telescoping pole with rotational Slip Ring Module on end


The Medium Gun Video Borescope System is functionally very similar to its large bore counterpart.  The Large Gun & Mortar Video Borescope is field-proven with hundreds of systems currently in use by the US Army.  The Medium Borescope System includes a camera head with both — a forward looking camera that presents an overview of the tube’s general condition, and a side looking camera for close-up inspection of the inside of the tube.  Both cameras are long-life, LED illuminated, and the side camera can be remotely focused.

The Medium Gun Video Borescope System uses the same LCD display/DVR as the large system, and can be purchased as a standalone complete kit or as an add-on to the large bore system.  As with the Large Gun System, the Medium Gun System includes the same useful features, including: exchangeable centering rings for multiple tube sizes, video and still image recording, orientation and camera depth readouts, digital measurement grids, and simple one person operation.
