2. Components Overview
The Teknetics Gamma 6000 Metal Detector consists of several key components designed for efficient and comfortable operation:
- Control Housing: Contains the LCD display, control buttons, and electronics.
- Adjustable Stem: Allows for length adjustment to suit user height.
- Padded Armrest: Provides comfort and stability during use.
- 8-inch Searchcoil: The primary detection component, designed for accuracy and sensitivity.
- Searchcoil Cable: Connects the searchcoil to the control housing.

3. Assembly and Initial Setup
- Assemble the Stem: Connect the lower, middle, and upper stem sections. Ensure the locking collars are tightened.
- Attach Searchcoil: Secure the 8-inch searchcoil to the lower stem using the provided bolt and nut.
- Mount Control Housing: Slide the control housing onto the upper stem. Adjust its position for comfortable viewing and access to controls.
- Wrap Cable: Carefully wrap the searchcoil cable around the stem, ensuring it is snug but not overly tight, to prevent tangling and false signals. Plug the cable connector into the port on the control housing.
- Install Batteries: The Gamma 6000 requires one 9V battery. Open the battery compartment on the control housing, insert the battery with correct polarity, and close the compartment securely.
- Adjust Armrest: Position the armrest for a comfortable fit on your forearm.
4. Operating Instructions
Familiarize yourself with the control panel and display before beginning operation.

4.1 Power On/Off
Press and hold the power button located on the control panel to turn the detector on or off.
4.2 Control Panel and Display
The LCD screen provides visual information, while the buttons allow for mode selection and setting adjustments.
- MENU Button: Accesses various settings such as Sensitivity, Discrimination Level, Notch, Number of Tones, and Volume.
- MODE Button: Toggles between detection modes: DISCRIMINATE, PINPOINT, ALL METALS, and GROUND GRAB.
- Arrow Buttons (+/-): Adjust selected settings up or down.
- Target-ID (I.D.): A two-digit numeric readout on the display that helps identify the probable type of metal detected.
- Depth Indicator: Estimates the depth of coin-sized objects.
4.3 Detection Modes
- DISCRIMINATE Mode: Allows the user to ignore unwanted metals (e.g., iron) and focus on specific target types. Adjust the discrimination level using the MENU and arrow buttons.
- ALL METALS Mode: Detects all types of metal without discrimination. This mode offers maximum depth and sensitivity.
- PINPOINT Mode: Used to precisely locate the exact position of a detected target before digging.
4.4 Key Settings
- Sensitivity: Adjusts the detector's responsiveness to targets. Higher sensitivity increases detection depth but can also increase susceptibility to electrical interference and ground mineralization.
- Ground Grab Computerized Ground Balancing: This feature automatically calibrates the detector to the specific soil conditions, reducing interference from mineralized ground. Activate via the MODE button and follow on-screen prompts. Always check the mineralization readout for optimal performance.
- Notch Filter: Allows for specific ranges of target IDs to be accepted or rejected, providing fine-tuned discrimination.
- Multi-Tone Audio: The detector provides different audio tones for various metal types, aiding in target identification without looking at the display. The number of tones can be adjusted.
- Volume: Adjusts the audio output level.
5. Maintenance
- Cleaning: Wipe down the detector with a damp cloth after each use. Avoid abrasive cleaners or solvents.
- Storage: Store the detector in a dry, cool place. Remove batteries if storing for extended periods to prevent leakage.
- Searchcoil Care: The searchcoil is waterproof, but the control housing is not. Avoid submerging the control housing.
- Cable Inspection: Regularly check the searchcoil cable for any signs of wear or damage.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector chirps or gives false signals constantly. | High sensitivity, electromagnetic interference, or improper ground balance. | Reduce sensitivity. Perform Ground Grab. Move away from power lines or other electronic devices. |
| Detector does not power on. | Dead or incorrectly installed battery. | Replace the 9V battery. Ensure correct polarity. |
| Settings are not retained after power off. | This model may reset some settings to default upon power cycle. | Re-adjust desired settings after powering on. Note down preferred settings for quick setup. |
| Poor detection depth or accuracy. | Incorrect ground balance, low battery, or high discrimination. | Perform Ground Grab. Replace battery. Reduce discrimination level or switch to ALL METALS mode. |
