This system can be particularly useful during the target identification stage before excavation.
10. Pinpointer System
The Pinpointer system is designed for precise target localization after a target has already been detected.
It progressively narrows the signal to help the user identify the target position more accurately.
The system also assists with estimating target depth and size.
11. Quick Scan System
Quick Scan is designed for rapid scanning.
When the search coil passes over a target, the system provides an audio alert and displays target information using colors.
According to the official AJAX page:
● Red indicates non-precious targets
● Black indicates precious targets
● Signal intensity increases as the operator approaches the target center
12. Spectrum Analyzer System
The Spectrum Analyzer system is designed for additional target analysis after locating a potential target.
It can perform a 2D scan and use successive pulses to analyze target characteristics and depth.
The system operates with one of the dedicated coils connected to the detector.
13. Automatic Geophysical System
The Automatic Geophysical system analyzes differences in electrical resistivity within the subsurface.
It is designed to help differentiate between:
● Metals
● Groundwater
● Different underground formations
