Why Choose a 2.9mm Borescope?
Many industrial inspection ports are designed exactly at 3.0mm. Standard 3.9mm scopes won't fit, while extremely thin 1.8mm scopes might sacrifice some lighting brightness.
The SPI φ2.9mm Video Borescope, distributed by QTS, is the perfect "Sweet Spot" solution—offering the best balance of accessibility, brightness, and image quality.
