The USA600J-4-1500 has been added to USA Borescopes economy videoscope line up because it offers end users the opportunity to upgrade from a lower cost fiberscope to an articulating videoscope with its own internal lightsource, video recording, picture taking, and SD card storage.  This unit features durable stainless steel sheathing as found in many other higher end videoscope systems.  This unit is a basic system to allow for a low cost inspection option.
