Fisher M101 Rebar Locator & Metal Probe with Double D Coil

Fisher M101 Rebar Locator with 4.5 kHz Double D Search Coil

The Fisher M101 is a handheld rebar locator and metal probe designed specifically for locating reinforcing bars and other embedded metal objects in concrete. Operating at 4.5 kHz with a Double D search coil, it provides concentrated signal detection with visual meter and audio indication for accurate target identification.

Precision Rebar Detection and Signal Control

• 4.5 kHz operating frequency for metal detection in concrete
• Double D search coil configuration for focused signal pattern
• Accuracy to 1/4 in. of rebar centerline
• 12:1 sensitivity adjustment range
• Analog meter with 1–100 linear scale output indication

Adjustable Penetration and Tuned Signal Response

The M101 features independent Sensitivity and Penetration controls that allow operators to adjust detection depth and narrow the signal field for precise centerline identification. When properly tuned, it can locate 1/2 inch diameter rebar at depths of 8 to 9 inches from the search coil.

Concrete Scanning & Embedded Metal Applications

• Locating reinforcing bar in concrete slabs, walls, and columns
• Detecting embedded conduit, wire mesh, and metallic objects
• Pre-drilling and structural inspection scanning
