Suitable for small defect detection.
Ideal for inspecting the bottom of holes that are in line with the opening.
Easy-to-handle pencil shape.
Available with Powerlink™ technology.
Wide range of lengths offered.
Available with bridge or reflection configuration.

Applications
Bottom of holes in aircraft piston housing.
Aircraft structure, unit, and engine inspection.
Through paint detection of stress corrosion cracking in stainless and carbon steel.
Surface crack inspection of manufacturing and transportation equipment.
