The ABEM GroundTEM i5 and i10 are user-friendly, app-controlled instruments that complement the existing WalkTEM range perfectly. They make groundwater and environmental TEM surveys more affordable, less complex, and quicker to deploy, with a one-box lightweight solution.
Redefining what you can expect from an entry-level system
The lower starting price of the GroundTEM range does not mean this is a ‘stripped-back’ system. It benefits from dual-moment output: measurements configured for both shallow and deeper responses are collected in a single measurement period, and then combined in the same data file. There is a choice of two transmitter loop sizes (20x20m and 40x40m) and a choice of flexible 3x3m receiver coil or our existing RC-5 antenna.
Fast in-field set-up and a user-freiendly mobile app simplifies use of the GroundTEM
Roll out the receiver coil, then the transmitter loop and attach both to the instrument. There is no right-or-wrong way to lay these out; they are not directional.
Start the GroundTEM App (Android and iOS), select a survey line and station number, then follow the on-screen prompts to choose a measurement script. The system is ready to go: select how long you wish to measure for and press the “play” button.
Lightweight, with all components shipped in a single Peli-style case
The whole system ships in a single transport case, with integral wheels and handles. Arrive on site, open the case and the instrument, transmitter loop, and receiver coil are ready to lay out. Power comes from two small Li-ion battery packs that mount inside the instrument case, removing the need for heavy, external 12V batteries.
The transport case (when loaded with the instrument, transmitter loops, receiver coil and battery charger) weighs under 32kg, and thus can be shipped as hold luggage on regular flights. In extreme cases, the system can be packed down into smaller cases for even easier transportation.

The TEM method is perfectly suited to locating groundwater and environmental surveys, but also useful for applications such as geological mapping and mineral exploration.
