Product Description

This borescope kit features a multi-coated objective lens that provides higher contrast and vivid color. It also has an independent focus ring for easy video and still photography.

The PSS04-NVK provides brighter light than competing borescopes due to the LightConcentrator™ and SuperNOVA™ LED technology.
