4.1. Assembly
The LOLARAN GT1000 features a foldable design for easy transport and storage. Follow these steps to assemble the detector for use:
- Extend the Shaft: Press the release button or latch to extend the telescopic shaft to your desired length. The adjustable length ranges from 26 to 49 inches (66 to 124 cm).
- Secure the Latch: Ensure the latch is securely fastened to lock the shaft in place.
- Adjust Search Coil Angle: Loosen the knob on the search coil, adjust the coil to be parallel with the ground, and then tighten the knob to secure it.
- Attach Handle (if separate): If the handle is separate, align it with the main unit and secure it with the provided screw or locking mechanism.

4.2. Battery Charging
The metal detector is powered by a built-in 2000mAh rechargeable lithium battery. Ensure the battery is fully charged before first use.
- Locate the USB charging port on the control unit.
- Connect the provided USB charging cable to the detector and to a standard USB power source (e.g., wall adapter, power bank, computer USB port).
- The LCD display will indicate charging status. A full charge typically provides over 20 hours of continuous use.
- Disconnect the charger once the battery is fully charged.

5. Operating Instructions
5.1. Power On/Off
Press and hold the power button located on the control unit to turn the detector on or off. The blue-backlit LCD screen will illuminate upon activation.
5.2. LCD Display and Controls
The large 3" x 2" LCD screen provides clear visibility of settings and detection information. Use the control buttons adjacent to the screen to navigate menus and adjust settings.
5.3. Operating Modes
The LOLARAN GT1000 offers six detection modes to suit various searching conditions and target preferences:
- ALL-METAL MODE: Detects all types of metal without discrimination. Ideal for general searching.
- DISC MODE (Discrimination): Allows you to set specific discrimination values to ignore unwanted metals (e.g., iron trash) and focus on desired targets.
- PINPOINT MODE: Used to precisely locate the exact position of a detected target in a small area, aiding in recovery.
- MEMORY MODE: Stores specific metal types you wish to detect and will only respond to those programmed metals.
- JEWELRY MODE: Optimized for finding jewelry, typically by excluding iron targets.
- GOLD & SILVER MODE: Specifically configured to detect gold and silver, often by focusing on specific conductivity ranges.

5.4. Sensitivity Adjustment
The detector features 8 adjustable sensitivity levels. Higher sensitivity increases detection depth but may also increase susceptibility to electromagnetic interference. Adjust sensitivity based on environmental conditions and desired detection depth.
Typical detection depth ranges from 4 to 10 inches, varying with target size, composition, and ground mineralization.
5.5. Waterproof Search Coil
The 10-inch search coil is waterproof (IP57 rated), allowing for effective detection in shallow water, wet grass, or sandy beaches. Note: The control unit and LCD display are NOT waterproof and must be kept dry.

6. Maintenance
- Cleaning: Wipe the search coil and shaft with a damp cloth after each use, especially after use in wet or sandy conditions. Ensure the control unit remains dry.
- Storage: Fold the metal detector for compact storage in the provided backpack. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: For long-term storage, charge the battery to approximately 50% every few months to maintain battery health.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not power on. | Battery is depleted. | Charge the battery using the provided USB cable. |
| No detection or weak signals. | Sensitivity too low; high ground mineralization; target too deep. | Increase sensitivity; try different operating modes; sweep slower. Note that deeper targets may be inconsistent. |
| False signals or erratic behavior. | High sensitivity; electromagnetic interference (EMI) from power lines, other electronics; highly mineralized soil. | Reduce sensitivity; move away from sources of EMI; perform ground balance if available (not explicitly mentioned, but general advice); switch to DISC mode. |
| Difficulty understanding settings. | Learning curve with advanced features. | Refer to this manual for detailed explanations of each mode and setting. Practice in a controlled environment. |
