Ensure storage tank integrity and safety with the NAVIC
Deliver state-of-the-art thickness inspection results with the NAVIC - Tank Scanner. Paired with the actuated probe lift, the NAVIC operates remotely at a distance of up to 30 m (100 ft), while offering steering control and the ability to raise and lower the probe. Powerful, magnetic wheels, drive vertically (and inverted) along the ferrous surfaces of tanks and vessels.
Motorized Driving and Steering
Variable drive speed and steering are controlled by the handheld controller.
Designed to handle intense tasks and challenging environments (dust tight, watertight)
Corrosion Thickness Probe Holder
Measure material thickness with a probe holder which may hold a host of different probe types.
Magnetic wheels provide the foundation for scan operations on ferrous surfaces
Navigate the crawler from up to 30 m (100 ft) away using the intuitive handheld remote control. The ergonomic handheld controller includes programming of raster patterns, drive paths and system diagnostics.
Enhance the NAVIC's capability with optional accessories: battery powered laser guide, onboard camera, backpack, cable management, crawler removal system and motorized couplant pump.

The powerful base crawler carries probe holder frames, raster arms and a multitude of accessories for the purposes of weld and corrosion inspection.
A spring-loaded encoder maintains surface contact on all various scan surface diameters.
Powerful magnetic wheels ensure the crawler remains fixed to any ferrous surface.
Compatible with both North American and European 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.
