FULLER ST200 4 LED Lights Edge Stud Finder
Instructions
POWER SUPPLY
The tools require one 9-volt battery to operate.
BATTERY INSTALLATION
- Squeeze the sides of the unit to help release the clip end.
- Slide 9V battery into compartment, terminal side first, matching (+) and (-) terminals from battery to case.
- Replace the clip. Battery life is approximately 50 hours.
Using the detector
- Position the unit flat against the wall.
- Press the on/off button and hold in.
- Slowly slide the unit horizontally across the wall, right or left. As you begin to approach a stud, the
Yellow LEDs will light, from bottom to top. - When the top Red LED is light and the beep sounds, you have located the edge of the stud.
Mark this spot. - Continue scanning beyond the marked spot until the yellow LEDs go out. Slide the unit in the reverse direction to locate the other edge of the stud.
- Mark this second spot. Between the two spots is the stud position.

FULLER ST200 4 LED Lights Edge Stud Finder-FAQs
How does a stud finder work?
Electronic stud finders detect changes in the dielectric constant of a wall. When the sensor passes over a stud, the reading drops, indicating its presence.
What is the Deep Scan mode on a stud finder?
DeepScan® mode allows the stud finder to detect studs through two layers of drywall, up to 1½ inches (38 mm) deep. The standard Stud Scan mode is for single-layer drywall up to ¾ inch (19 mm) thick.
How does a stud finder detect electrical wires?
A stud finder identifies electrical wiring by sensing variations in wall density. Move the tool horizontally and vertically to trace the wiring path accurately.
What is the purpose of a stud in a wall?
Studs provide structural support, holding windows, doors, insulation, and utilities in place. They can bear weight or serve as partitions to separate spaces.
How do I check if my stud finder is working?
Simply slide the stud finder across a wall. If it beeps or lights up when passing over a stud, it’s functioning properly.
How can I trace the path of a wire in a wall?
Using a stud finder is a safe way to trace wires. Hover the device over the wall, and it will indicate the wire’s presence through lights or sound.
What does the AC light on a stud finder mean?
The AC detection feature identifies live electrical wires up to 2 inches deep. Sequential LEDs and audible signals provide guidance.
What makes a stud finder function?
Stud finders work by detecting density changes within the wall. Some models use magnets to locate screws or nails, while others measure electrostatic fields to identify studs.
