4-Way Articulating Borescope Series – Precision in Every Direction

When 2-way isn't enough, the Ralcam 4-way articulating borescope gives you independent control in all four directions — up, down, left, right — letting you steer precisely around corners, through bends, and into cavities that a fixed-head or 2-way scope simply can't reach.

Every 4-way articulating borescope in this series features a 360° joystick or rocker control, HD imaging (1280×720 to 1920×1080), IP67 waterproof probe, and a built-in screen or smartphone connection for hands-free viewing. Probe diameters start at 3.9 mm for tight spark plug access, up to 8.5 mm for industrial pipes.

Used by aviation MRO technicians for turbine blade inspection, automotive mechanics for GDI valve and piston checks, HVAC engineers for evaporator coil cleaning, and NDT professionals for weld and crack detection, Ralcam 4-way articulating borescopes deliver the control and clarity that demanding inspections require.
