Non-intrusive surveys and target investigation using magnetometers and GPR are two techniques that are commonly used in various fields, including archaeology, construction, and unexploded ordnance (UXO) surveys.
Magnetometers
Detect ferrous objects in the ground from the ground surface
Can be used for UXO surveys to detect ferrous anomalies in the ground, which could be munitions, bombs, or other dangerous threats
Can be used in construction to detect underground pipes, cables, and other metallic objects
detection and mapping of all sizes of ferrous objects including anchors, chains, cables, pipelines, ballast and other scattered shipwreck debris, aircraft, engines, and any other magnetic objects
GPR
Uses radar pulses to image the subsurface
Can detect changes in soil density, moisture content, and other subsurface features
Can be used in construction to detect underground utilities, voids, and other features
Can be used in UXO surveys to further assess anomalies identified during magnetometer surveys
GPR system is applicable to detect small objects with a diameter starting from 8cm and large objects like tunnels or other man-made structures
Aerial magnetometry and GPR surveys with drones
DroneRover products are GPR and magnetometer devices that can be attached to drones to perform scanning in hazardous environments without compromising the safety of staff, providing an additional solution for more efficient surveying.
These devices can survey larger or even inaccessible areas and provide both manual and completely automated scanning. Findings can be visualized in 2D and 3D and/or exported to 3D mapping software for further processing.
Handheld light and portable detectors with 3D object visualization and augmented reality mapping
TreasureDetectors products are lightweight and portable, capable of detecting targets up to 35m/114ft in depth, detecting metallic and non-metallic objects, and displaying object size, shape, and depth. Objects can be visualized in 2D and 3D on any smartphone and also mapped in a real-world environment using the augmented reality scan feature, which also provides the best resolution available on the market.
Applications of use:
in the mining industry to locate and extract natural mineral deposits
identify the location and distribution of different types of rocks, surficial deposits, and geologic structures such as faults and folds
small object detection / UXO detection on unreachable, flooded, or mined areas
underground pipes detection
geological surveys for layers profiling before serious area development or construction works
subsurface mappings/mapping of underground infrastructure and inaccessible areas
spaces/void detection in a concrete slab or beam
locating buried steel drums, tanks, pipes, and iron debris in trenches and landfills.
rapid inspection of buried pipelines without contact
