The ATS Inspector from Aircraft Tool Supply has a built-in digital recorder that takes still images and videos and records them onto an SD card. The semi-ridge probe on this unit is 5 mm diameter. Included in this package are three mirror tips; 70-degree forward oblique, 90-degree right angle, and a 100-degree rear oblique for valve inspections. It has four bright pure white LEDs with intensity control providing you with outstanding lighting for the job. It features lateral lighting, a feature in which an extra set of LED lights are located on the side of the probe, which when activated, successfully eliminates the glare and spots that are sometimes present when looking through a mirror.
