How Fisher Metal Detectors Work: A Guide for Beginners and Enthusiasts
If you’re curious about how Fisher metal detectors operate, the magic behind their technology, and how to get the most out of these impressive machines, this article is for you. Whether you’re an aspiring treasure hunter, a hobbyist, or considering your first metal detector purchase, understanding how Fisher detectors work will give you the confidence to get started. Let’s walk through their function, benefits, usage tips, and some practical advice!
What Are Fisher Metal Detectors?
Fisher metal detectors are specialized electronic devices designed to locate metal objects buried beneath the ground or hidden in other materials. Founded in the 1930s, Fisher Labs stands as one of the pioneers of metal detection technology. Known for their reliability and innovation, Fisher detectors are widely used by both hobbyists and professionals worldwide—for everything from coin shooting and relic hunting to gold prospecting and beachcombing.
Key Features of Fisher Metal Detectors
- Advanced signal processing
- Adjustable sensitivity and discrimination
- Variety of search modes (coin, jewelry, relic, etc.)
- Ergonomic and lightweight designs
- User-friendly interfaces
How Do Fisher Metal Detectors Work?
Let’s unravel the science in simple terms.
1. The Basic Principle: Electromagnetic Induction
A Fisher metal detector operates on the principle of electromagnetic induction. Here’s how it works:
- Transmitting Signal: The search coil at the bottom of the detector sends out an electromagnetic field into the ground.
- Interaction with Metal: When this field encounters something metallic, electric currents (called ‘eddy currents’) are generated within the object.
- Receiving Signal: These eddy currents create their own magnetic field, which is picked up by the detector’s receive coil.
- Processing and Alert: The detector processes this received signal and notifies you, usually with a sound, visual display, or both. The signal’s characteristics help tell you about the size and possibly the type of metal detected.
2. Discrimination Technology
One of the standout features of Fisher detectors is discrimination—the ability to distinguish different types of metals. This reduces the time spent digging up trash, helping you focus on valuable finds. By tweaking discrimination settings, you can filter out unwanted metals like iron while zeroing in on coins, jewelry, and precious relics.
3. Ground Balancing
Minerals in soil can interfere with detection. Fisher’s ground balancing feature adjusts the detector to ignore most mineral interference, increasing your accuracy and depth of detection. Many models offer automatic and manual ground balancing to suit both beginners and seasoned users.

Step-By-Step Guide: Using a Fisher Metal Detector
Getting started is easy:
- Assemble the Detector: Follow the manual to connect the shaft, control box, search coil, and armrest.
- Adjust for Comfort: Set the shaft length so the coil is close to the ground while you stand upright.
- Turn On and Set Up: Power on the device. Select the desired mode (e.g., jewelry, coins, relics).
- Set Sensitivity and Discrimination: Tweak these settings for your target and local conditions.
- Start Sweeping: Move the coil slowly in side-to-side arcs, overlapping each sweep.
- Pinpointing: Once you get a signal, use the detector’s pinpoint function to narrow down the exact location.
- Dig Carefully: Retrieve your find with minimal ground disturbance.
- Fill Holes and Respect Sites: Always refill holes and follow local regulations and ethical guidelines.

- Solution: Reduce sensitivity, adjust ground balance, and avoid power lines or heavy electronic use nearby.
Unwanted Targets
- Cause: Detector picking up junk metals
- Solution: Use discrimination features to ignore pull-tabs, nails, and iron objects.
Depth Limitations
- Cause: Very small or deeply buried objects may escape detection
- Solution: Use larger coils, higher-sensitivity models, or revisit areas with upgraded equipment.
Practical Tips for Using a Fisher Metal Detector
To get the best results from your detector, keep these tips in mind:
- Go Slow: Sweep gently and methodically for the best chance of finding deep targets.
- Overlap Your Sweeps: Ensure you don’t miss areas by overlapping each pass by around 50%.
- Check Your Batteries: Fresh batteries power your detector more consistently and effectively.
- Stay Patient: Great finds often come to those who persist.
- Keep a Log: Jot down locations, settings, and finds to discover patterns over time.
