Operating Instructions
1. Power On/Off
- To power on, press and hold the power button on the control box until the screen illuminates.
- To power off, press and hold the power button again until the device shuts down.
2. Mode Selection
The Simplex Ultra WHP offers various search modes optimized for different environments and target types. Use the mode selection buttons to cycle through available modes such as Field, Park, Beach, and All Metal. The waterproof design allows for seamless transition between land and water environments.
3. Ground Balancing
Ground balancing is crucial for stable operation and accurate detection, especially in mineralized soils or saltwater beaches.
- Select the appropriate search mode for your environment.
- Hold the search coil parallel to the ground, about 1-2 inches above the surface.
- Press and hold the ground balance button while pumping the coil up and down over the ground. Release the button once a stable ground balance reading is achieved.
4. Using the AccuPoint Pinpointer
The AccuPoint Pinpointer helps to precisely locate targets after the main detector has identified a general area.
- Once a target is detected with the main unit, carefully dig a plug of soil.
- Turn on the AccuPoint Pinpointer and sweep it over the excavated soil or inside the hole to narrow down the target's exact location.
- The pinpointer will emit an audio and/or vibration alert, increasing in intensity as it gets closer to the target.

- Waterproofing: Regularly inspect all O-rings and seals for any signs of wear or damage. Ensure they are clean and properly seated before submerging the detector.
- Storage: Store the metal detector in a cool, dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not power on | Low battery; loose cable connection | Charge the battery; check all cable connections, especially the search coil cable. |
| Erratic signals or false positives | Improper ground balance; electromagnetic interference; highly mineralized soil | Perform ground balance; move away from power lines or other electronics; adjust sensitivity settings. |
| Wireless headphones not connecting | Headphones not in pairing mode; low battery on headphones or detector; interference | Ensure headphones are in pairing mode; fully charge both devices; try re-pairing in a different location. If issues persist, power cycle both devices. |
