UltraTEM

Advanced Geophysical Classification Technology

The UltraTEM is a next-generation technology that allows for metal object searches with high fidelity. It was developed by GapEOD in partnership with Black Tusk Geophysics to overcome problems with outdated equipment common in the industry. The UltraTEM uses three-component electromagnetic receivers in combination with a powerful transmitter. The high clarity of the data produced allows for dependable discrimination of close-by objects of various sizes. This translates into investigations that are cheaper, faster and smarter.

UltraTEM Configurations

The UltraTEM system configuration is flexible and can be optimized to suit the project requirements. The system is available for service or lease in the following configurations:

• Towed-Array Classifier (TNB): The UltraTEM Towed-Array Classifier (TNB) is GapEOD’s most advanced system and was the first system validated through DAGCAP in 2019. The towed-array system features 11 receiver cubes and 5 transmitter coils. The system features suspension to reduce motion noise in the data and can be configured at 3 ride heights to suit site terrain.

• Towed-Array Screener (TPC):  The UltraTEM Towed-Array Screener (TPC) is optimized for rapid area search and features 6 receiver cubes and 2 transmitter coils. An additional 3rd large transmitter loop can be added to increase depth of detection.

• Pedestrian Classifier (TNC): The UltraTEM Pedestrian (TNC) system can operate as either a Classifier or Screener system depending on survey speed. The system utilises 6 receiver cubes and 2 transmitter coils. The system is versatile and can be configured as a single-person push-cart, a two-person carried array, or a hybrid push-carry setup. Switching between configurations is quick and straightforward, allowing operators to adapt the platform to site conditions throughout a project.

• XC Classifier (TND): The UltraTEM XC Classifier (TND) is designed to survey small and inaccessible areas and features 6 receiver cubes and 2 transmitter coils. An additional 3rd transmitter loop can be added for static or dynamic cued surveys.

• UltraTEM Deep Search: The UltraTEM Deep Search configuration is deployed when deep ordnance detection is the overriding priority. In this configuration a large loop of copper wire is laid around the survey area and the field crew survey inside the wire loop using an UltraTEM receiver system. The loop configuration can be dictated by terrain and space limitations of the survey area within certain constraints imposed by the desired detection depth. Loops are typically larger than 10 by 10 meters but can be rectangular with side length up to 100 m.
