10″ Drag Bit (4-wing)

High-Power Transmission & Fast Shutdown
WTEM’s robust transmitter delivers large power output and a rapid shutdown mechanism that extends detection range and improves resolution, especially in shallow surveys.
Superior Anti-Interference Capability
Built to withstand electrical noise such as atmospheric interference and 50/60 Hz industrial signals, the WTEM system ensures high-quality data in even the most challenging environments.

Versatile Configuration
The WTEM receiver pairs with either high-power transmitters for deep exploration or smaller transmitters for shallow investigations, giving you flexible deployment across project types.
Advanced Synchronization
Support for multiple synchronization modes — including cable and GPS synchronization — ensures precise timing and stable data acquisition across survey sites.
Lightweight & Efficient
Designed with portability and low power consumption in mind, the WTEM system performs reliably in the field while minimizing logistical complexity.
User-Friendly Interface
An intuitive control interface simplifies setup and data collection, while integrated software tools support real-time monitoring and post-survey analysis.
