Setup
Assembly
- Unpack Components: Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present, including the control pod, carbon fiber shaft, M11 coil with skidplate, and adjustable armrest.
- Attach Coil: Securely attach the M11 coil to the lower shaft section. Ensure the connection is firm.
- Assemble Shaft: Connect the lower, middle, and upper sections of the carbon fiber shaft. The MANTICORE features a collapsible design, allowing adjustment from 24.8 inches (630 mm) to 56.7 inches (1440 mm) for comfortable use and transport.
- Mount Control Pod: Attach the control pod to the upper shaft. Ensure it is oriented correctly for easy viewing and access to controls.
- Connect Cables: Connect the coil cable to the control pod. Ensure the magnetic USB charging connector is accessible for future charging.
- Adjust Armrest: Position the adjustable armrest for comfortable and stable operation.

Charging the Battery
The MANTICORE is powered by a rechargeable Lithium Ion battery (included). Before first use, fully charge the detector using the provided magnetic USB charging connector. A full charge ensures maximum operating time.
Operating Instructions
Power On/Off
Press and hold the Power On/Off button located on the control pod to turn the detector on or off.

Multi-IQ+ Technology
The MANTICORE utilizes Minelab's Multi-IQ+ technology, which transmits more power through the coil at a wider range of operating frequencies simultaneously. This enhances target detection and identification in various ground conditions.

Figure 5: Visual representation of Multi-IQ+ technology, illustrating how multiple frequencies are transmitted through the coil to detect targets.
Search Modes
The MANTICORE offers 10 customizable Search Modes to optimize performance for different environments:
- All-Terrain: Optimized for inland detecting.
- Beach: Optimized for sand, surf, and seawater zones.
- Goldfield: Optimized for detecting gold nuggets.
Select the appropriate mode using the controls on the display. Customization options allow you to fine-tune settings within each mode.

Advanced Target ID and Discrimination
The 2D Target ID map provides visual information about detected targets, helping to differentiate between desired items and trash. Enhanced discrimination features allow you to reject unwanted ferrous targets.
- Discriminate: Create custom discrimination patterns to accept good targets and reject bad ones.
- Classify Targets: Ferrous Limits help maximize detectability of targets among ferrous trash.
- Assign Audio: Customize pitch and volume for up to 5 tone regions to amplify targets you want to hear.

Figure 8: Illustration demonstrating the MANTICORE's fast response and exceptional target separation performance, showing how it can distinguish a desired target (coin) from ferrous trash (nails) underground.
Audio and Lighting
The MANTICORE includes customizable audio controls and integrated lighting features for various detecting conditions:
- Customizable Audio: Adjust audio settings to confidently identify targets and reduce noise.
- Flashlight: Integrated flashlight for low-light conditions.
- Handgrip Vibration: Provides tactile feedback for target detection.
- Display and Keypad Backlight: Ensures visibility of the display and controls in dim light or at night.

Maintenance
- Cleaning: After each use, especially in wet or dirty conditions, wipe down the detector with a damp cloth. Ensure all connections are dry before storage. The MANTICORE is waterproof up to 16 ft (IP68), but proper cleaning helps prevent residue buildup.
- Coil Care: Inspect the search coil for any damage or wear. The included skidplate helps protect the coil during use.
- Battery Care: Store the detector with a partially charged battery if not in use for extended periods. Avoid fully discharging the battery frequently to prolong its lifespan.
- Storage: Store the detector in a cool, dry place, away from direct sunlight and extreme temperatures. The collapsible design allows for compact storage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not power on. | Low or depleted battery. | Charge the battery fully. |
| No target response. | Incorrect search mode or sensitivity settings. | Adjust sensitivity and ensure correct search mode for the terrain. Check coil connection. |
| Excessive false signals. | High electromagnetic interference or ground mineralization. | Reduce sensitivity. Perform ground balance. Adjust discrimination settings. |
| Audio issues (no sound/distorted). | Headphones not connected properly or volume too low. | Check headphone connection and volume settings. Ensure wireless audio is enabled if using wireless headphones. |
