2. Setup and Assembly

Follow these steps to assemble your allsun TS20A metal detector:

1. Unpack Components: Carefully remove all parts from the shipping carton. You should have the main detector unit, the adjustable shaft, the search coil, the electronic torch, and a small screwdriver.
2. Prepare the Handle: Unscrew the plastic clip's screws on the handle section.
3. Attach the Shaft: Align the locating protrusion on the right cover of the handle with the locating hole near the end of the upper stem and at the right side of the stem. The direction of the electronic torch clip should correspond with the handle.
4. Secure the Handle: Tighten the screws to secure the plastic clip and handle firmly to the shaft.
5. Install Flashlight Battery: Take out the electronic torch from its clip. Unscrew its cap and install the required battery (ensure correct polarity). Reinstall the cap and place the torch back into its clip.
6. Install Main Unit Battery: Hold down the battery compartment cover on the main unit and slide the cover off in the direction of the arrow. Insert one 9V, 6F22 battery or equivalent, ensuring correct polarity. Reinstall the battery cover.
7. Secure Search Coil: Rotate the shaft lock nut counter-clockwise to secure the lower shaft, which is connected to the search coil.

3. Operating Instructions

To achieve optimal detection results, follow these operating guidelines:

1. Power On and Initial Sensitivity Adjustment: With the search coil held approximately 10-20 cm (4-8 inches) away from the ground, turn the power/sensitivity knob clockwise until you hear a continuous alarm sound.
2. Fine-tune Sensitivity: Slowly turn the knob counter-clockwise until the continuous alarm just stops. This is the optimal sensitivity setting for the current environment, balancing detection range with false signals.
3. Begin Searching: Sweep the search coil slowly and steadily across the ground, keeping it parallel to the surface. When a metallic object is detected, the detector will emit an audio alarm.
4. Pinpointing: To pinpoint the exact location of the object, move the search coil in a cross-pattern over the area where the alarm was strongest. The alarm will be loudest directly over the target. Ensure the search coil is 90 degrees perpendicular to the detected object for best results.
5. Using the Electronic Torch: If operating in low-light conditions, activate the electronic torch for improved visibility.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your metal detector:

• Cleaning: After each use, wipe down the detector with a damp cloth to remove dirt, dust, and moisture. Avoid using abrasive cleaners or solvents.
• Battery Care: Always remove the 9V battery from the main unit if the detector will not be used for an extended period to prevent battery leakage and damage.
• Storage: Store the metal detector in a dry, cool place, away from direct sunlight and extreme temperatures.
• Search Coil: While the search coil is waterproof, the main control unit (IP20 rated) is not. Avoid submerging the main unit in water.

5. Troubleshooting

If you encounter issues with your allsun TS20A metal detector, refer to the following common troubleshooting tips:

• No Power:
  • Check if the 9V battery is correctly installed with proper polarity.
  • Replace the 9V battery with a fresh one.
  • Ensure the power/sensitivity knob is turned ON.
• No Detection or Weak Signal:
  • Adjust the sensitivity knob as described in the Operating Instructions (Section 3).
  • Ensure the search coil is close enough to the ground and parallel to the surface.
  • Test with a known metal object to confirm functionality.
• Constant or False Alarms:
  • Reduce the sensitivity by turning the knob counter-clockwise slightly.
  • Move away from areas with high electrical interference (e.g., power lines, other electronic devices).
  • Ensure the search coil is not touching the ground or any vegetation.
