Using a Woodworking Metal Detector To Prevent Blade Damage
Using a Woodworking Metal Detector To Prevent Blade Damage
Woodworking is a fulfilling and creative pursuit, but using reclaimed or recycled wood comes with certain challenges. Undetected metal objects in the wood, such as nails, screws, and other debris, can lead to damaged tools and potential safety hazards. The Lumber Wizard 5 and Little Wizard II Woodworking Metal Detectors are valuable resources for woodworkers, specifically designed to identify and pinpoint hidden metal objects, promoting safe and efficient woodworking.
The Lumber Wizard 5: 
Tailored for Woodworkers. The Lumber Wizard 5 sets itself apart from ordinary metal detectors with its thoughtful design crafted to meet the unique demands of woodworkers. Featuring an ergonomic shape and a laser line indicator, this detector excels at scanning reclaimed or recycled wood for concealed metal objects.
Key Attributes of the Lumber Wizard 5:
Laser Line Indicator: The Lumber Wizard 5 incorporates a built-in laser line indicator at the center of its 2" x 6" detection coil, enabling you to maintain a consistent scanning plane and facilitating the discovery of metal objects beneath the wood's surface.
Ergonomic Shape: The detector's ergonomic design is tailored specifically for wood scanning. Its elevated handle ensures comfortable scanning while preventing knuckle scraping as you glide the detector across the wood's surface. Additionally, the design allows the detection coil to remain parallel to the wood's surface for a more effective scan.
Highly Sensitive Detection: The Lumber Wizard 5 is engineered to detect even the tiniest metal items concealed under the wood's surface. Its unique design offers superior detection capabilities compared to angled coils, ensuring no potential hazards or damage-inducing objects go unnoticed.
Using the Lumber Wizard 5:
-
Hold at least three feet from large metal items such as planers, bandsaws, tablesaws, etc. Turn on the Lumber Wizard 5 and allow 5 seconds for the automatic tuning to set..
-
Grasp the detector by its elevated handle, ensuring a comfortable grip while keeping your knuckles away from the wood's surface.
-
Place the detection coil flat on the wood's surface, with the laser line indicator pointing directly downward.
-
Gently and consistently move the detector back and forth across the wood's surface, using the laser line as a reference to maintain a uniform scanning plane.
-
When the Lumber Wizard 5 identifies a metal object, it will produce an audible alert or laser line (based on your preferred settings). Mark the detected object's location for future removal or avoidance during your woodworking project.
-
Continue scanning the entire wood piece, marking all detected metal objects.
-
After completing the scan, safely extract any detected metal objects from the wood or modify your woodworking plans to prevent cutting or drilling into the marked areas.
In Summary: The Lumber Wizard 5 Woodworking Metal Detector is an indispensable tool for woodworkers using reclaimed or recycled wood. Its ergonomic design, laser line indicator, and highly sensitive detection capabilities make it an ideal ally for promoting safe and efficient woodworking. Safeguard your tools, avoid injuries, and guarantee the success of your projects by incorporating the Lumber Wizard 5 into your woodworking toolkit.
The Little Wizard II Woodworking Metal Detector
Ergonomic Handheld Design
The Little Wizard II is designed for comfortable, one-handed operation during extended scanning sessions. Its compact, lightweight form allows precise control without wrist fatigue, making it ideal for inspecting boards, slabs, reclaimed lumber, and finished surfaces. The flat detection face ensures stable contact with wood, improving accuracy while reducing hand strain.
Adjustable High-Sensitivity Detection
An adjustable sensitivity control allows users to fine-tune detection for maximum accuracy. This lets the operator balance sensitivity and stability depending on wood thickness, density, and metal size. Proper tuning enables the Little Wizard II to detect small embedded metal at depths appropriate for woodworking and planing, helping protect blades without excessive false alerts.
LED Array Metal Proximity Indicators
An integrated LED array provides visual confirmation of metal proximity, supplementing the audible alert. As metal is approached, the LEDs illuminate to indicate signal strength and location, making it easier to pinpoint embedded objects—especially in noisy shop environments. The visual indicators improve precision, reduce guesswork, and help confirm detection before cutting or planing.
How to Use the Little Wizard II
(Handheld Woodworking Metal Detector)
1. Install the Battery
-
Use a fresh 9-volt alkaline battery (very important for accuracy).
-
Insert the battery and close the compartment securely.
2. Power On & Initial Setting
-
Turn the dial to the center position.
-
The unit will emit a tone—this is normal.
3. Fine-Tune (Critical Step)
-
Hold the detector away from all metal.
-
Slowly turn the dial counter-clockwise until the sound just stops.
-
This sets the detector at its most sensitive, stable point.
👉 If it chatters or beeps continuously, you’re too sensitive—back it off slightly.
4. Scan the Wood
-
Hold the face of the detector flat against the wood surface.
-
Move slowly—about 1–2 inches per second.
-
Scan in overlapping passes, like mowing a lawn.
5. Pinpoint Metal
-
When you hear a beep:
-
Stop.
-
Move the detector back and forth in short strokes.
-
The strongest sound marks the metal’s location.
-
-
Mark the spot with chalk or pencil.
6. Before Cutting or Planing
-
Re-scan the area after marking.
-
For planing: remember most passes remove 1/64"–1/32", so shallow detection is exactly what you want to protect blades.
Tips for Best Results
-
✅ Always use a new battery
-
✅ Scan slowly
-
✅ Re-tune if temperature or environment changes
-
❌ Don’t test it on your workbench (often metal underneath!)
-
❌ Don’t crank sensitivity to max—it reduces accuracy
