Double-Frequency Metallic Mine Detector
Single-frequency mine detectors struggle in seawater and magnetic soil, which is exactly where they are often needed. This double-frequency detector is built to work across that full range of ground: laterite, clay, magnetic soil, beach and fresh or salt water, from -40°C to 55°C. Positioning accuracy is 4 cm or better to the mine edge, with mean detectivity of 97% or above.
Key benefits
- Works in seawater and magnetic soil where single-frequency detectors cannot
- Positioning accuracy of 4 cm or better to the mine edge
- Mean detectivity of 97% or above
- 24 hours or more continuous working on lithium battery
- Waterproof to 1 metre depth and rated -40°C to 55°C
Problems it solves
- Traditional single-frequency detectors fail in electrically conductive ground
- Magnetic soil generates false responses that mask real targets
- Imprecise localisation means excavating a larger area than necessary
- Short battery life forces a team off the ground mid-task
Who it is for
- Demining teams working across varied terrain
- Units operating in coastal or waterlogged ground
- Operators supplementing a vehicle-mounted detection system
Application scenarios
- Personnel mine detection on foot
- Supporting equipment for vehicular military mine detectors
- Beach, laterite, clay and magnetic soil conditions
- Fresh water and seawater search conditions
Technical features
- Double-frequency operation for high sensitivity and resolution
- Accurate static localisation
- Three selectable sensitivity settings
- Automatic low voltage alarm
- Intelligentised design for simpler operation

Customisation options
- Lithium battery or three LR20 cells
Compared with other models in the range
A hobby or security metal detector loses usability the moment the ground is wet or mineralised. This detector is specified around exactly those conditions, with published detectivity and positioning accuracy figures rather than general sensitivity claims.
Use guide
- Set the staff between 750 and 1450 mm for the operator
- Select one of the three sensitivity settings for the ground type
- Work the 250 mm coil in overlapping passes for full coverage
- Use static localisation to narrow the position to within 4 cm of the edge
- Watch for the automatic low voltage alarm toward the end of a 24-hour cycle

Double-Frequency Metallic Mine Detector FAQ
Does it work on wet or mineralised ground
Yes. It is specified to operate in seawater, fresh water, laterite, clay, magnetic soil and beach soil, which is where single-frequency detectors fail.
How accurately does it locate a target
4 cm or better, measured between the marked location and the mine edge.
What detection depth does it achieve
12 cm or more for a GLD111 anti-personnel mine and 13 cm or more for a GLD212 anti-tank mine.
How long does it run
24 hours or more on lithium battery, with an automatic low voltage alarm.
Is it waterproof
Waterproof at 1 metre depth.
How heavy is it
2.9 kg or less with the lithium battery, or 3.2 kg or less with three LR20 cells.
