The review
The metal detector features an S-shaped shaft composed of three sections. The upper and middle sections are crafted from aluminum alloy, while the lower section is constructed from carbon fiber, which can withstand significant loads. This design not only enhances durability but also provides excellent rigidity.
The upper and middle shaft sections are coated with a wear-resistant powder paint, ensuring they maintain their appearance even with extensive use. The middle section includes eight adjustment holes, allowing users to customize the shaft length for optimal comfort.
For secure attachment, the shaft fixation system employs spring buttons and camlocks equipped with swivel washers. This system allows for easy adjustments while ensuring a stable connection between the shaft sections.
Attached to the upper shaft section are the control unit and a handler featuring an adjustable armrest. The armrest is designed for comfort, with a deep profile that securely holds the user’s forearm. It is padded with a special foam material to prevent numbness during extended use. Additionally, the armrest can be shifted along the upper shaft for personalized positioning.
The design includes two holes for attaching a fixation strap, available as an optional accessory. The handler is made from soft polyurethane, which remains warm to the touch, adding to the comfort during use.
While the control unit is permanently attached to the shaft, the overall design of the metal detector allows it to be disassembled into a compact size, making it easy to store in a bag or backpack.
The coil
The Teknetics Gamma 6000 operates at a frequency of 7.8 kHz, which is widely regarded as versatile for metal detection. This frequency allows the device to effectively locate both small objects, such as coins, and larger items, like relics or artifacts. The Gamma 6000 utilizes the very low frequency (VLF) operating principle, ensuring reliable performance across various detection scenarios.
Equipped with a round 8-inch mono coil, the searchcoil is designed as a single, solid piece, eliminating the need for additional protection on the bottom. This design enhances durability and ease of use. The coil features an elastic wire with a threaded jack plug, ensuring it remains securely connected and does not unplug unexpectedly, even in cold conditions (down to -10 °C).
Importantly, the searchcoil is completely waterproof, allowing users to search in wet environments. However, it’s essential to remember that the coil can only be submerged to the level of the control unit to prevent water damage.
The headphones
Headphones are not included in the standard package of the Teknetics Gamma 6000 metal detector. However, users can connect any standard headphones with the appropriate jack plug.
The control unit features two headphone outputs on the left side: one measuring 1/8 inch and the other 1/4 inch, accommodating a wide range of headphone types for a customizable listening experience.
The battery
The Teknetics Gamma 6000 metal detector is powered by a single 9V battery, providing an operational time of approximately 20 to 25 hours. Using headphones can extend the battery life even further, allowing for longer detecting sessions without needing a replacement.
While users have the option to utilize rechargeable batteries, these typically offer around 8 to 9 hours of continuous operation. This shorter lifespan may necessitate more frequent recharging, which could be a consideration for those planning extended treasure hunts.
The control unit
The control unit of the Teknetics Gamma 6000 metal detector is designed to be thin and lightweight, yet it houses a battery holder and a large LCD display with control buttons conveniently located on the front panel. Let’s explore the functionality of the control buttons and the display indicators.
The metal detector features six control buttons. The upper button in the center, which is oval-shaped, serves to power the device on and off. Below it, the PINPOINT button activates the precise target detection mode.
The Gamma 6000 powers on quickly after pressing the power button, initially set to the maximum sensitivity level. To adjust this sensitivity, users can easily press the two large buttons marked “+” and “-.”
The “+” and “-” buttons adjust various device settings, while the side buttons allow users to switch between search modes and adjustment functions.
The center of the display shows a discrimination scale diagram, with the VDI number displayed directly below it.
In the top left corner of the LCD, a two-segment battery charge indicator informs users about battery status. When only the frame of the indicator is visible, it’s time to recharge the accumulator or replace the battery.
The top right corner displays ground balance information, represented by an icon of a crossed pickaxe and shovel. The Teknetics Gamma 6000 offers both manual and automatic ground balance functions.
On the right menu sidebar, users can access the ground balance mode labeled GROUND GRAB, along with options for ALL METAL, PINPOINT, and DISCRIMINATE modes.
The left menu sidebar allows for adjustments in SENSITIVITY, DISC. LEVEL, and selective discrimination patterns (NOTCH). Users can also choose the number of sound tones (ranging from 1 to 4) and adjust the VOLUME.
During the treasure-hunting process, the detection depth scale (measured in inches) appears below the VDI number. While this depth value is approximate, it provides essential information for successful target digging.
Discrimination
The Teknetics Gamma 6000 metal detector features a discrimination scale consisting of eight segments, each corresponding to a specific type of metal or object. This scale is crucial for distinguishing between valuable finds and unwanted materials during treasure hunting.
The semicircular dial on the display indicates which types of targets may be located beneath the search coil. The eight segments of the discrimination scale are as follows: IRON, FOIL, USA 5 cents (NICKEL), pull tabs (PULLTAB), screw caps (S-CAP+), USA zinc penny (ZINC), USA 10 cents (DIME), and USA 25 cents (QTR+).
When a metal target is detected, a VDI number appears on the display alongside an active marker under the corresponding segment of the discrimination scale. This combination provides the user with valuable information regarding the nature of the detected object and whether it’s worth digging.
The Teknetics Gamma 6000 offers two options for setting the discrimination pattern. In standard discrimination mode, the device sequentially excludes all objects from the search coverage, starting from the ‘IRON’ mark. This allows users to operate without having to exclude metals from the search or deactivate parts of the discrimination scale.
If a user wants to deactivate a specific segment in the middle of the scale—such as Nickel—the NOTCH function comes into play. This feature allows users to selectively exclude one or more segments from the discrimination scale. By using the adjustment buttons, you can create a personalized discrimination pattern that signals only valuable targets, improving the efficiency of your treasure hunting efforts.
Search modes
The Teknetics Gamma 6000 features three dynamic search modes: All Metal, Discrimination Mode, and Selective Discrimination (NOTCH). These modes require the search coil to be moved above the ground for optimal functionality.
In All Metal mode, the detector responds to all metal signals present in the ground, regardless of the type of metal. This mode is ideal for general treasure hunting, allowing users to detect a wide range of targets without any discrimination.
In contrast, Discrimination Mode filters signals based on target type. While this allows users to avoid unwanted metals, it results in a shallower detection depth compared to All Metal mode. Therefore, it is beneficial for those focusing on specific valuable items, such as coins or jewelry.
The Selective Discrimination (NOTCH) mode provides even greater control, enabling users to exclude specific segments of the discrimination scale. This customization allows for a tailored detecting experience, focusing only on the targets that interest the user while minimizing interference from less desirable items.
Sound indication
Users of the Teknetics Gamma 6000 can customize their detection experience by adjusting the tone settings. The device allows for a four-tone signal indication, where each type of metal target corresponds to its unique response tone. This feature enables diggers to identify targets more easily and make informed decisions about whether to dig based on the sound alone.
Alternatively, users can simplify their audio feedback by selecting a two-tone signal option. This flexibility in tone settings can be particularly useful in varying environments or for users who prefer less auditory complexity.
In addition to tone adjustments, the volume level of the detector can also be customized. This means you can purchase headphones without a built-in volume control, as the Gamma 6000 allows for quick and convenient volume tuning directly from the device. Such features contribute to a more tailored and enjoyable metal detecting experience.
Pinpoint
The Teknetics Gamma 6000 features a precise search mode known as PINPOINT, which operates as an “all metal” mode but in a static manner. In this mode, users can move the search coil slowly above the ground or even leave it stationary to receive a signal from the detected target. This capability is particularly advantageous in areas with dense debris or multiple targets, allowing for precise identification of valuable finds without the need for continuous movement.
Ground balance
A key distinction of the Teknetics Gamma 6000 compared to other metal detectors in its product line is its adjustable ground balance function. All soil types contain varying amounts of minerals, which can interfere with target signal reception.
While beginner-level metal detectors come with a manufacturer preset ground balance, the Gamma 6000 allows users to customize the settings for specific soil conditions, both manually and automatically.
When properly adjusted, the metal detector achieves greater detection depth, enhances target identification accuracy, and minimizes unwanted signals. This capability results in significantly improved performance compared to devices with fixed or preset ground balance values.
For everyday treasure hunting, the automatic ground balance function is typically sufficient. However, when operating in challenging soil conditions, manually adjusting the ground balance is advisable to maximize detection depth and overall efficiency.
Conclusions
Teknetics Gamma 6000 is rather good metal detector, but it has some drawbacks. Firstly, it is quite strange that the metal detector with such price has a mono coil. Secondly, even though that the device has better functionality than that of
Garrett Ace 200, it is worse than the one provided by Bounty Hunter Land Ranger Pro or Fisher F44.
If I had a choice between Teknetics Gamma 6000 and the latter two devices, I would choose Bounty Hunter Land Ranger Pro for treasure hunting in the field, and Fisher F44 for beach hunting. These models seem more user-friendly to me, they have many positive feedback reviews and acceptable price.
