Introduction
The Teknetics LIBERATOR is a high-performance metal detector designed for various treasure hunting and metal detecting applications. It features advanced capabilities such as V-Break variable tone breakpoint, pinpoint mode with depth indication, and computerized ground balancing. This manual provides essential information for setting up, operating, and maintaining your LIBERATOR metal detector to ensure optimal performance and longevity.
Safety Information
Always exercise caution when using the metal detector. Be aware of your surroundings, especially in areas with potential hazards like uneven terrain, sharp objects, or buried utilities. Do not operate the detector near active electrical lines or in hazardous environments. Always obtain permission before detecting on private property. When digging, use appropriate tools and be mindful of potential underground obstacles. Keep the device away from extreme temperatures and moisture to prevent damage.
Setup and Assembly
Proper assembly is crucial for the performance of your Teknetics LIBERATOR. Follow these steps carefully:
- Attach the Searchcoil: Secure the 11-inch waterproof DD searchcoil to the lower stem using the provided bolt and washers. Ensure it is firmly attached but do not overtighten.
- Assemble the Shaft: Connect the lower, middle, and upper stems. Adjust the length of the shaft to a comfortable position that allows the searchcoil to be parallel to the ground when you are standing upright.
- Mount the Control Housing: Slide the control housing onto the upper stem. Ensure it is securely fastened.
- Install Batteries: The LIBERATOR requires one 9V battery. Locate the battery compartment on the control housing, open it, and insert the battery, observing the correct polarity. Close the compartment securely.
- Connect the Searchcoil Cable: Carefully wrap the searchcoil cable around the stem, leaving enough slack for the coil to pivot. Plug the cable connector into the corresponding port on the control housing. Ensure the connection is snug to prevent signal interference.

Operating Instructions
Familiarize yourself with the control panel and its functions to effectively use your metal detector.

Basic Operation
- Power On/Off: Press and hold the power button (usually marked with a power symbol) to turn the detector on or off.
- Adjust Sensitivity: Use the sensitivity controls (often labeled SENS or with +/- buttons) to adjust the detector's sensitivity. Higher sensitivity increases depth but can also increase false signals in mineralized ground.
- Ground Grab (Computerized Ground Balancing): This feature automatically cancels out ground mineralization signals. Press the "Ground Grab" button and pump the searchcoil up and down over the ground until the ground balance reading stabilizes. This is crucial for stable operation.
- Search Modes: The LIBERATOR offers 2 search modes. Consult the on-screen display or specific buttons to switch between modes, such as All-Metal or Discrimination modes.
Advanced Features
- Discrimination: This function allows the detector to ignore unwanted metals (like iron) and respond only to desired targets. Adjust the discrimination level using the DISC controls. The LIBERATOR supports motion and no-motion discrimination.
- Variable Notching: Use the notching feature to selectively eliminate specific ranges of target IDs from detection. This is useful for ignoring common trash items.
- V-Break (Variable Tone Breakpoint): This allows you to set a specific target ID point where the audio tone changes. For example, you can set it so that iron produces a low tone, and non-ferrous metals produce a higher tone.
- Target-ID Numbers (1-99): The large 2-digit numeric display provides a Target-ID number, helping you identify the probable type of metal detected before digging. Higher numbers generally indicate more conductive metals.
- Pinpoint Mode with Depth Indicator: Press the "PP" (Pinpoint) button to activate pinpoint mode. This helps you narrow down the exact location of a target and provides an estimated depth reading on the display.
- 4-Tone Audio-ID: The detector provides distinct audio tones for different types of metals, aiding in target identification without constantly looking at the display.
Maintenance
Proper maintenance will extend the life and performance of your Teknetics LIBERATOR.
- Cleaning: After each use, wipe down the searchcoil and stem with a damp cloth to remove dirt and debris. The 11-inch DD searchcoil is waterproof and can be rinsed with fresh water, but ensure the control housing is kept dry.
- Battery Care: Always remove the 9V battery if the detector will not be used for an extended period to prevent leakage and damage to the electronics. Store batteries in a cool, dry place.
- Storage: Store the detector in a dry, temperate environment. Avoid exposing it to extreme temperatures or direct sunlight for prolonged periods.
- Cable Inspection: Periodically check the searchcoil cable for any signs of wear, cuts, or damage. Ensure the connector is clean and free of corrosion.
Troubleshooting
If you encounter issues with your Teknetics LIBERATOR, try these common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power or intermittent power | Dead or improperly installed battery; loose cable connection. | Replace the 9V battery with a fresh one. Ensure the battery is inserted with correct polarity. Check that the searchcoil cable is securely connected to the control housing. |
| Excessive false signals or chatter | High sensitivity setting; improper ground balance; electromagnetic interference. | Reduce the sensitivity setting. Perform a proper Ground Grab procedure. Move away from power lines, cell phones, or other electronic devices. |
| Poor target identification or depth | Incorrect discrimination settings; highly mineralized ground; coil not parallel to ground. | Adjust discrimination settings to allow desired targets. Re-ground balance. Ensure the searchcoil is swept parallel to the ground surface. |
| No audio response | Volume too low; faulty headphones (if used); internal issue. | Increase the volume. Test with different headphones or without headphones. If the problem persists, contact customer support. |
