Revolutionary Groundwater Mapping
The tTEM geoscanner revolutionizes land-based groundwater mapping. It is designed to be towed by an All-Terrain Vehicle (ATV) / Quad bike to create high-resolution subsurface layer images. The system can be configured with different sizes of the transmitter coil by changing the length of the fiberglass beams (wings) carrying the coil. This makes it possible to easily adapt the system for specific survey requirements and field conditions, if a survey requires a certain depth of investigation, a large coil with maximum area can be mounted. Or if a survey needs to be carried out in tracks, a smaller coil which fit the width of the tracks can be mounted.
Surveys cover areas from tens to thousands of hectares (2 – 2000 acres), with a depth of investigation ranging from a meter or two below the surface to an impressive 180-200 meters (600 – 650 feet) depending on configuration. The area of the transmitter coil directly affects the depth of investigation, with larger area resulting in deeper penetration. Increasing the number of turns also increases the depth of investigation but it comes at the expense of losing the very shallow layer resolution.
The tTEM system comes with:
- 331: 3×3, single turn. 3 m wide
The default tTEM system
- 333: 3×3, three turns. 3 m wide
Deeper investigation than 331, but less focus on shallow layer resolution.
- 222: 2×2, two turns. 2 m wide
Same depth of investigation as 331.
Because of the smaller width it can access fields with narrow driving tracks.
