Once you’ve completed these steps, your Fisher F22 is ready for its first use!
Shaft
The Fisher F22 features a standard S-shaped shaft comprised of three sections, designed for durability and ease of use.
Starting with the bottom section, it is constructed from solid carbon fiber, providing exceptional strength and resilience under high loads. This material is also resistant to corrosion, making the F22 suitable for various environmental conditions. A plastic bolt secures the coil to this section, with seal rings at the fixture point to protect the plastic components from wear and tear.
The middle section is made from a lightweight aluminum alloy, enhancing the overall portability of the detector. This combination of carbon fiber and aluminum makes the F22 lightweight, an essential feature for users who may spend hours searching for treasures. The middle section also includes a jam nut on one side for added stability.
Along the length of the shaft, there are nine adjustment holes that allow users to customize the shaft length to their height, ensuring comfortable handling during use. This ability to adjust the shaft length not only accommodates users of different heights but also allows for greater versatility in various detecting scenarios, such as searching in tight spaces.
At the top, the curved upper section includes a clamping nut, a permanently attached control unit, a soft handle, and a comfortable armrest, all designed to enhance user experience and reduce fatigue during extended detecting sessions. The ergonomic features, including the soft handle and comfortable armrest, are designed to minimize strain, making the detector suitable for users of all skill levels. Additionally, the S-shaped design not only adds to the aesthetic appeal but also improves balance during operation, allowing for more accurate target detection.
Control unit
The control unit of the Fisher F22 metal detector is equipped with a large LCD, ensuring that all notifications and graphical icons are clearly visible. This feature significantly saves time during treasure hunting, allowing users to focus on their search without unnecessary distractions.
In the center of the display, two digits represent the VDI (Visual Discrimination Indicator) value of the detected metal target. This value helps users differentiate between valuable targets and less desirable metal debris, enhancing the efficiency of their searches. The VDI feature not only helps distinguish between metals but also provides a numerical value that indicates the type of metal detected, enhancing user confidence in their findings.
Above the VDI value, a nine-segment discriminator spans the entire width of the display. By disabling specific discriminator segments, users can adjust the device to search for particular targets, tailoring their experience to their needs.
To the left of the display, a menu allows users to adjust the search mode and discrimination function settings. Two indicators—search depth and battery charge—are positioned near the menu. Notably, the depth indicator provides three levels of feedback, while the battery charge indicator offers seven levels. This detailed battery information minimizes the chances of an unexpected stop during searches due to battery depletion.
The Fisher F22 features four pre-set search modes, with the currently active mode displayed in the right corner of the LCD. This aspect distinguishes it from the F44 model, which offers five search modes.
Under the LCD, there are six control buttons. The far-right button is for turning the device on and off. The MODE button allows users to select the search mode, while the PP button activates the precise target localization mode. The MENU button lets users navigate menu options, and the ‘+’ and ‘-’ buttons adjust device parameters.
On the opposite end of the control unit, a 3.5 mm headphone jack is securely covered with a rubber plug, preventing moisture and dust ingress. This thoughtful design detail ensures that users can rely on their device in various outdoor conditions.
Power supply
On the right side of the control unit, there is a tightly sealed compartment for the batteries. A notable improvement in the Fisher F22 is that it now operates on just two lightweight, compact, and affordable AA batteries. This enhancement is made possible by the design that incorporates new, power-efficient electronic components.
These components are housed in a special box that fits snugly within the control unit and is secured with a cover. While the box can be removed by pulling on a small strap, this method can feel unreliable, as it requires significant force to extract the box. Many users may find themselves hesitant to pull the strap, fearing it might break during use.
With two alkaline batteries, the Fisher F22 can operate for up to 30 hours, offering an impressive runtime. If rechargeable batteries are used, the device can perform continuously for up to 15 hours. This extended operating time is noteworthy, as many metal detectors from well-known brands struggle to achieve such longevity.
The coil
The Fisher F22 is equipped with a unique 5×9 mono coil, featuring a concentric design with an operational frequency of 7.69 kHz. This distinctive drop-shaped coil makes it particularly convenient for searching in hard-to-reach areas. While the F44 model has a similar coil, its size measures 11 inches, compared to the F22’s more compact 9-inch coil.
Interestingly, the F22 coil does not come with the standard removable protection for the working surface. However, it boasts an unconventional form of protection that significantly enhances its durability, ensuring it withstands the rigors of outdoor use.
Additionally, the coil wire is soft, maintaining its elasticity even in cold weather, which helps to prevent damage during use.
The Fisher F22 is versatile when it comes to coil options; it is compatible not only with its own 9-inch coil but also with standard coils from the F11 and F44 metal detectors. Furthermore, brands such as NEL and Detech offer a complete series of coils specifically designed for this product line. This variety makes it easy for users to select the coil that best suits their needs.
Although the coil mounting bracket may appear somewhat flimsy, it is surprisingly robust, ensuring a secure connection during operation.
Search modes
The Fisher F22 metal detector utilizes nine discrimination segments to identify various types of metal. The discrimination scale is organized into three distinct sections, known as bands in the device manual: IRON, GOLD, and SILVER. The IRON section contains a single segment (FE), while the GOLD and SILVER sections each comprise four segments.
An interesting feature of the F22 is its detection system. When metal is detected from a distance, the specific segment may not be displayed, nor will a tone signal sound. However, the frame of the entire section will appear. The segment and corresponding tone signal become active only when the target is closer, providing a more accurate detection experience.
The VDI (Visual Discrimination Indicator) values, which range from 1 to 99, further assist users in distinguishing between different metals.
The F22 operates in one of four search modes: Jewelry, Coin, Artifact, and Custom. A notable advancement in this model is the ability to disable any of the nine discrimination segments using the NOTCH function, which enhances flexibility compared to previous Fisher models. Importantly, all program changes are saved even when the device is turned off.
In CUSTOM mode, users can select from five available tones (numbered 0 to 4). This adjustment is straightforward: after selecting CUSTOM mode, press and hold the MODE button for two seconds to activate tone adjustment based on the segments. Users can navigate between segments using the MENU button, with an audible tone indicating the current segment.
The F22 also features adjustable sensitivity, allowing users to modify it within a range of 1 to 10. A new addition for beginners is the volume adjustment function, which can be set from 0 (silent) to 20.
As with all Fisher metal detectors, the ergonomic design of the F22 ensures it is comfortable to use and nearly weightless in hand. Additionally, the device includes a pinpoint function, making it easier to locate targets accurately.
Conclusion
In summary, the Fisher F22 metal detector is an excellent choice for both beginners and experienced treasure hunters seeking a reliable and user-friendly device. While it may be somewhat outdated compared to newer models, it still offers straightforward assembly, effective discrimination features, and impressive battery life, making it a valuable option at an affordable price. Although it lacks some advanced features found in the F44 model, such as manual ground balance and an LCD backlight, it compensates with its lightweight design and ease of use. Whether you’re exploring parks, beaches, or historical sites, the Fisher F22 stands out as a versatile tool that delivers quality performance, ensuring that you can uncover hidden treasures with confidence.
