Define the electrical contrast the survey needs to resolve
TEM surveys observe the time-varying response after a transmitting loop is switched off. GEOTEM-19Rad uses a coplanar compensation arrangement intended to improve access to the early response relevant to shallow investigations.
A meaningful enquiry describes the target geometry, likely host materials, surface access and sources of electrical interference. Ask whether TEM is suitable for that target and what validation is needed, rather than assuming that every pipe, void or aquifer produces an unambiguous signal.

Select the coil and transmitter as a complete survey package
The source describes compensated shallow work and other loop arrangements for different investigations. Coil geometry, transmitter settings and receiver timing belong to one specified configuration; the gallery does not establish that every possible loop is included.
Request the intended loop dimensions, connection diagram, battery arrangement and acquisition sequence. Agree how site interference, coupling and repeat measurements will be checked before committing to a survey coverage or productivity target.
Agree data, interpretation and field acceptance
The receiver table lists two acquisition channels, 32-bit conversion and USB transfer. These are instrument characteristics, not independent evidence that a particular geological target will be detected or classified correctly.
Confirm data formats, processing and inversion software scope, licences, field training and acceptance measurements. The source contains broad depth examples and case narratives; this reference uses neither as a GLOBSEEK survey result or a guarantee for a new site.

Planning your configuration
- Describe the target, site geology, electrical noise, access and required data deliverables. Request a method and configuration review plus representative field validation.
- Coil-specific depth, marketing accuracy and case-success claims are not adopted. Confirm the supplied instrument build, software and accessories; no stock or GLOBSEEK survey history is asserted.
