Its central-probe design replaces conventional overlapping-loop arrangements, helping simplify field deployment and improve operational flexibility across different terrains.
With configurable transmitter loop sizes and integrated data acquisition and processing capabilities, the GT-10 is suitable for mineral exploration, groundwater investigation, goaf detection, and engineering geological surveys.
Receiver + transmitter + power supply all-in-one, 10 kg, 403×330×178 mm, with built-in battery operating for over 8 hours.
Output current 150A, max power 3.6 kW, bipolar square wave (duty cycle 1:1), pulse width 10/20/40 ms.
Replaces the conventional overlapped-loop setup, smaller in size and lower failure rate, delivering accurate results in both mountainous and flat terrain.
Integrated acquisition, processing, forward/inverse modeling, and automatic result output; supports remote data management and real-time upload via wired + wireless dual channels.
