4. Mark this spot with a pencil.
5. Continue sliding past the stud until the beep stops. Now reverse direction.
6. When the unit beeps again, mark the opposite edge.
7. The center is exactly midway between your two marks.

⚠️ Step 3: Understanding the Warnings (AC & Metal)

The FatMax 400 is popular because it detects more than just wood.

AC Wire Detection:

• If the unit detects an unshielded live AC wire, a specific "AC" icon will light up, or the unit will beep continuously even when moving.
• Safety Warning: Always turn off the main power before drilling or nailing into walls where AC is detected. The manual warns that wires deeper than 2 inches or shielded by metal conduit may not be detected.

Metal vs. Wood:

• The manual clarifies that this is a "density finder." It cannot differentiate between a wood stud, a metal pipe, or a PVC pipe with water in it. If the red light goes off, there is something dense there.
