Introduction to the Fisher F22 Metal Detector
The Fisher F22 represents a significant advancement in entry-level metal detecting technology. Released as part of Fisher’s modern lineup, this detector bridges the gap between basic models and professional-grade equipment. With its lightweight design and intuitive controls, the F22 has become a popular choice for both newcomers to the hobby and seasoned detectorists seeking a reliable backup unit.
The F22 operates on a 7.69 kHz frequency, which provides excellent sensitivity to a wide range of targets including coins, jewelry, relics, and even some gold nuggets. Its weather-resistant construction and submersible search coil make it suitable for various detecting environments, from dry fields to shallow water hunting.
Key Features and Specifications
The Fisher F22 comes packed with features that enhance its detecting capabilities:
– **Frequency**: 7.69 kHz VLF (Very Low Frequency)
– **Search Modes**: 4 preset modes (Jewelry, Coin, Artifact, Custom)
– **Discrimination**: 10-segment visual target ID
– **Sensitivity**: 8 adjustable levels
– **Ground Balance**: Fixed
– **Coil**: 9-inch triangulated concentric, waterproof
– **Weight**: 2.3 lbs (1 kg)
– **Batteries**: 2 AA (lasts 25-30 hours)
– **Operating Frequency**: 7.69 kHz
The 10-segment visual target ID system displays numbers from 0-99 on the LCD screen, helping users identify potential targets before digging. The four preset search modes allow quick adaptation to different hunting scenarios without manual adjustment of multiple settings.
Weather-Resistant Design
One of the standout features of the F22 is its weather-resistant construction. The control housing is sealed against moisture, and the 9-inch search coil is fully submersible. This design allows users to detect in light rain or wet grass without concern. But it’s important to note that the control box itself is not waterproof and should not be submerged.
Performance in the Field
The Fisher F22 delivers impressive performance across various detecting environments. In coin shooting scenarios, the 7.69 kHz frequency provides excellent depth on most coins, typically detecting US quarters at depths of 8-10 inches in moderate soil conditions. The detector’s discrimination capabilities effectively filter out most iron and foil trash while maintaining sensitivity to valuable targets.
In relic hunting applications, the F22’s adjustable sensitivity and discrimination settings allow users to fine-tune their search based on site conditions and target types. The artifact mode is particularly useful for relic hunting, as it accepts a wider range of conductive targets while still rejecting most iron.
Depth and Target Separation
The F22’s 9-inch concentric coil provides good depth penetration for its class. Users can expect to detect:
– US quarters: 8-10 inches
– US dimes: 6-8 inches
– US pennies: 6-7 inches
– US nickels: 6-7 inches
Target separation is adequate for most hunting situations, though the concentric coil design means it may struggle slightly more than DD coils in areas with heavy trash concentration.
Practical Tips for Using the Fisher F22
Ground Balancing Techniques
While the F22 features fixed ground balance, users can optimize performance in mineralized soil by adjusting sensitivity. Start with mid-range sensitivity settings and increase gradually until you experience chatter or false signals. Then reduce sensitivity slightly to achieve stable operation.
In highly mineralized ground, consider using the “Coin” mode rather than “Jewelry” mode, as it provides better stability in challenging soil conditions.
Pinpointing Targets
The F22 features a static pinpoint mode activated by holding the pinpoint button. For more accurate pinpointing:
1. Center the target response and press and hold the pinpoint button
2. Move the coil side to side to determine the widest signal point
3. Move the coil forward and backward to confirm the center
4. The target should be directly below the center of the coil at the strongest signal point
Audio Tone Adjustments
The F22 offers three distinct audio tones that can be customized based on target conductivity:
– Low tone: Iron and foil (typically rejected)
– Medium tone: Pull-tabs and smaller gold items
– High tone: Coins and larger jewelry
Experiment with the tone break settings to create audio patterns that match your hunting style and target preferences.
Search Coil Options
While the standard 9-inch concentric coil performs well in most situations, consider these alternatives for specific applications:
Nel Tornado Coil
The Nel Tornado is a 5-inch coil that offers improved target separation in trashy areas. While it sacrifices some depth compared to the stock coil, it excels at finding small targets in iron-infested sites.
Nel Big Coil
For open areas with minimal trash, the Nel Big Coil (11-inch) increases ground coverage and depth potential. This larger coil is particularly effective for cache hunting and deep coin shooting in parks and fields.
Coil Installation
To change coils on the F22:
1. Remove the mounting screw and retaining washer from the lower rod
2. Slide off the existing coil
3. Attach the new coil, ensuring proper alignment
4. Replace the washer and screw, tightening securely but not over-tightening
Maintenance and Care
Proper maintenance ensures long-term reliability of your Fisher F22:
Cleaning Procedures
After each use, wipe down the control housing and coil with a damp cloth to remove dirt and moisture. For stubborn deposits, use mild soap and water, avoiding harsh chemicals that could damage the finish.
Battery Care
The F22 uses standard AA batteries, providing 25-30 hours of operation. For optimal performance:
– Remove batteries if the detector won’t be used for extended periods
– Clean battery contacts periodically with a cotton swab and rubbing alcohol
– Consider rechargeable AA batteries for cost savings over time
Storage Recommendations
Store your F22 in a cool, dry place away from direct sunlight. If possible, use a padded case to protect the detector during transport. Avoid storing the detector with the search coil pressed against the control housing, as this can cause wear on the cable.
Common Issues and Troubleshooting
False Signals
If experiencing intermittent false signals:
1. Check battery strength – weak batteries often cause instability
2. Reduce sensitivity settings
3. Ensure the coil cable is properly wrapped and secured
4. Check for interference from power lines or other detectors
Intermittent Audio
For sporadic audio issues:
1. Verify the headphones are properly connected
2. Check the volume control for debris or damage
3. Test with different headphones to isolate the issue
4. If problems persist, contact Fisher customer service
Comparing the F22 to Other Models
F22 vs. F44
The Fisher F44 offers several upgrades over the F22:
– Digital target ID numbers (0-99) vs. F22’s 10-segment categories
