The RF System Lab 2.8mm VJ-Advance video borescope has all the same features as the original, flagship 6.9mm VJ-Advance, including four-way joystick-controlled camera articulation, medical grade camera technology, and trigger activated image capture. However, as indicated by the name, the 2.8mm VJ-ADV offers a much slimmer insertion tube diameter, allowing inspection of much tighter spaces. It is ideal for casting inspection because of its slender size and smaller bending radius, allowing it to easily navigate through tight corners and small tubing to detect corrosion or FOD. It is also used to perform preventive avionics maintenance to ensure that the welding is fully sealed and that there are no ruptures or leakage in the joints of the casting.
