Armand Prospector 4 Metal Detector
The Armand Prospector 4 is a professional analog VLF metal detector designed for prospecting, treasure hunting, and general metal detection in the field. Manufactured by Armand in Poland, the Prospector 4 combines a traditional analog detection system with practical features designed for comfortable and straightforward operation.
Operating at 7.8 kHz, the detector can detect both ferrous and non-ferrous metals and provides Static and Dynamic operating modes. Its metal discrimination function allows the user to distinguish unwanted metal targets according to the detector's response.
The Prospector 4 is manually assembled and tested in Poland. Its lightweight 1.25 kg construction, folding design, adjustable armrest, waterproof search coil, and built-in rechargeable battery make it suitable for extended field use and easy transportation.

Detection Modes
The Armand Prospector 4 offers two operating modes:
Static Mode
Static operation allows the detector to respond to metal targets while the search coil is used in a controlled manner over the ground. This mode can be useful for locating and examining detected targets.
Dynamic Mode
Dynamic operation is designed for continuous searching while moving the search coil across the ground. It is suitable for systematic field searches and general prospecting.
The detector also features metal discrimination, allowing users to reduce the response to selected unwanted targets.
Ground Adjustment and Operation
The Prospector 4 features an automatic zeroing function that helps adjust the detector's operation to changing ground conditions. This provides a practical way to maintain stable operation while searching across different areas.
The controls are designed for straightforward operation, making the detector suitable for users who prefer a traditional analog metal detector with direct controls rather than a complex digital interface.
Lightweight and Portable Design
With a total weight of approximately 1.25 kg, the Armand Prospector 4 is designed for comfortable field operation. The adjustable armrest and folding construction make the detector easier to carry and store.
The 28.5 cm search coil is waterproof, providing additional protection when searching in damp environments or on wet ground. The detector itself should not be submerged unless specifically stated by the manufacturer.
Built-in Rechargeable Battery
The Prospector 4 uses a built-in rechargeable battery and includes a mains charger. According to the manufacturer, a full charge provides approximately 15 hours of operation, depending on operating conditions and usage.
A battery level indicator helps the user monitor the remaining charge during operation.
Additional Functions
The detector includes several practical features for field searching:
-
LED target indication
-
Audio target signal
-
Headphone output
-
Built-in LED flashlight
-
Battery level indicator
-
Automatic zeroing
-
Folding mechanism
-
Adjustable armrest
The built-in flashlight can be useful when searching in low-light conditions or when examining a target after detection.

Applications
The Armand Prospector 4 can be used for a variety of general metal detection applications, including:
-
Metal detecting and prospecting
-
Treasure hunting
-
Coin searching
-
Searching for historical metal objects
-
Searching for military-related metal objects
-
General field exploration
-
Locating larger buried metal objects
Actual detection depth and performance depend on the target size and composition, soil mineralization, moisture, orientation of the target, search coil position, and other environmental conditions.
