The industry-leading NAVIC is JIREH's most powerful, all-encompassing, weld and corrosion scanning solution.
The NAVIC 2 - Base Crawler is a modular, motorized, steerable scanner that carries various attachments for scanning and inspection applications. The list of possibilities is seemingly endless with this industry-leading crawler. The NAVIC can perform circumferential and longitudinal inspections on ferrous tanks, pipes, and vessels.
Motorized Driving and Steering
Variable drive speed and steering control.
Designed to handle intense tasks and challenging environments (dust-tight, watertight).
Effortlessly perform corrosion mapping with a variety of automated raster arms.
Various probe holder frame configurations allow for carrying between 2 and 6 probes during weld inspection.
Increased capability with pod separation, multiple encoders, accessory mounts and a handheld controller.
Enhance the NAVIC's capability with optional accessories: battery-powered optical guide, onboard camera, backpack, cable management, preamp and motorized couplant pump.
Magnetic wheels provide the foundation for scan operations on ferrous surfaces.
Low Profile Design
The NAVIC can circumnavigate pipes as small as 7 cm (2.75 in) OD while only requiring 7 cm (2.75 in) of radial clearance when low-profile scanning is needed.
Program scan and raster paths from up to 30 m (100 ft) away using the intuitive handheld remote control. The ergonomic handheld controller also includes drive paths, variable speed control, system diagnostics and more.
JIREH backs the NAVIC system with a limited 3-year warranty.

The powerful base crawler carries probe holder frames, raster arms and many accessories for weld and corrosion inspection.
A spring-loaded encoder maintains surface contact on all various scan surface diameters.
Robust magnetic wheels ensure the crawler remains fixed to any ferrous surface.
Compatible with North American, European and UK power sources, the power controller connects the user instrument and handheld controller to the base crawler.
The backbone of communication between the power controller and the base crawler.
Containing the NAVIC operating system, the handheld controller joysticks control speed and steering of the base crawler while the intuitive touchscreen allows for more intricate raster path and drive programming.
