The USAVS2-4-1500 has been added to USA Borescopes economy videoscope line up because it offers end users the opportunity to upgrade from a lower cost fiberscope, typically ranging in price from $3,000-$6,000, to an articulating videoscope with its own internal light source, video recording, picture taking, and SD card storage. Most fiberscopes offer 2-way articulation and if this is what you have used in the past you will be familiar with this range of motion at the distal tip.
