4. Operating Modes
The Gbnryg X55J Metal Detector offers five distinct operating modes to optimize your search for various metal types and environments.
Figure 4.1: Visual representation of the five detection modes: PP Mode, Learn Mode, Custom Mode, All Metal Mode, and Beach Mode.
- All Metal Mode: This mode detects all types of metal. The detector will provide an audio notification as soon as any metal is found, without discrimination.
- Discrimination (Disc) Mode: Allows you to differentiate between detected metal types and ignore unwanted items, often referred to as 'junk'. This mode helps filter out specific metal signals.
- Memory Mode: This innovative mode allows you to focus on a single, specific metal type. The detector will remember the pattern of a desired metal and primarily alert you to its presence.
- Jewelry Mode: Optimized for finding jewelry, this mode is designed to enhance signals from precious metals commonly used in jewelry while filtering out other types.
- Pinpoint (PP) Mode: Used to precisely locate the exact position of a detected target. Once a target is found in another mode, switch to PP mode to narrow down its location, saving time during excavation.
5. Operation
Understanding the control unit and making proper adjustments will enhance your metal detecting experience.
5.1 Control Unit and LCD Display
The control unit features a large, backlit LCD display for easy reading of detection information. It shows target ID, depth, battery level, sensitivity settings, and current operating mode.

5.2 Adjustments
- Sensitivity: The detector offers 5 sensitivity adjustments. Adjusting sensitivity helps reduce unnecessary signals (false positives) and allows you to focus on genuine targets. Higher sensitivity can detect deeper targets but may also pick up more interference.
- Volume: There are 3 volume levels to adapt to different environmental noise conditions. Use headphones for clearer audio signals, especially in noisy areas.
- Backlight: The LCD display has a backlight feature for visibility in low-light conditions.
- On/Off Memory Function: The built-in memory function ensures that your last settings are retained when the detector is turned off and on again, eliminating the need to reset it every time.
5.3 Using the IP68 Waterproof Search Coil
The 12-inch search coil is rated IP68, making it suitable for exploring beaches and shallow water. This allows for detection in damp or submerged conditions. Important: The main control unit is NOT waterproof and must be kept dry at all times.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your metal detector.
- Cleaning: After each use, especially in sandy or wet conditions, wipe down the search coil and stem with a damp cloth. Ensure the control unit remains dry. Do not use abrasive cleaners.
- Battery Care: Remove batteries if the detector will not be used for an extended period to prevent leakage. Store batteries in a cool, dry place.
- Storage: Store the metal detector in a dry, temperate environment. The collapsible design allows for compact storage in the provided backpack.
- Cable Inspection: Periodically check all cables and connections for any signs of wear or damage.
7. Troubleshooting
If you encounter issues with your Gbnryg X55J Metal Detector, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power or display | Dead or incorrectly installed batteries | Replace batteries with fresh ones, ensuring correct polarity. |
| Inconsistent or no audio signal | Low battery, loose headphone connection, high interference, incorrect mode/sensitivity settings | Check battery level. Ensure headphones are fully plugged in. Reduce sensitivity. Switch to 'All Metal' mode to test basic function. Move away from electrical interference. |
| False signals or excessive noise | High sensitivity, electromagnetic interference, mineralized ground | Reduce sensitivity. Move away from power lines, cell phones, or other electronic devices. Try 'Discrimination' mode to filter out unwanted signals. |
| Difficulty pinpointing targets | Incorrect use of PP mode, target too deep | Ensure you are in 'Pinpoint' mode. Sweep the coil slowly over the target area in an 'X' pattern to narrow down the location. |
If the problem persists after trying these solutions, please contact Gbnryg customer support for further assistance.
