We have developed a system that can profile through drilling mud

Survey down 1,000’ (300 m) depth or more, Up to 60’ diameter or larger.

The system can be shipped by air cargo.

Carries marine cameras, sonars, & client specified sensors

An in house designed system that can be deployed through 6” boreholes
Depths of 1,000’ attainable

170 ft. range

Better than 10 mm accuracy.

SHAFTS & BOREHOLE SURVEYS

Deliverables include processed images as well as XYZ point clouds


CAD ready data

Flooded mine stope surveyed through five boreholes 6 inch diameter


Our survey was used to correct old drawings

Rock drilled borehole, above water

Sonar cross-section image of an excavated deep (1,400’) pile. The image shows two large boulders that impeded the bucket.

Use for volume calculations
Tie multiple surveys together
2,500’ system tether lengths available
Useful sonar range of 50 m
Sound footprint, approx.3% of range
Tie into local co-ordinate systems.
