SOURCE: How to operate the Stanley Stud Finder

Hi Gene,

  • Place the unit flat against the wall.
  • Press and hold the button.
  • The LED will come on for a second or two then go out.
  • Slowly move the unit laterally until the LEDs come on again.
  • When they top out, that is the beginning of the stud.
  • When they start to go back down, that is the end of the stud.
That's about it..

Best regards
Mike

SOURCE: I have plaster walls in

Your stud finder keeps beeping because old plaster walls have lath boards behind the plaster that are attached to the studs and running horizontally. Try adjusting the sensitivity of the stud finder by placing it on the wall and turning the sensitivity down until it just stops beeping. Then move it back and forth in a wide enough arc to be sure that you have crossed a stud, turning up the sensitivity ever so slightly until you get a tone when you cross a stud. Hope this works out for you.

Without knowing what room you are using it in it could be a underlayment of wire mesh that you are reading. If it is an older home this was used often as a backing for plaster instead of lath.Thank you.

Red light doesn't go off on stanley studfinder


Hi Laurie,

I think you might have confused the calibration set up in the first step of the directions. This must be done each time the unit is powered on, placed on a different wall, or whenever it is providing ambiguous indications. For you convenience, I have pasted the operation manual below. You should download and review the entire manual - free of charge here.

1) Hold the Stud Sensor 50 flat against the surface making firm contact.

2) Press in and hold the activation button. The green
and red LED's will light. When the red LED goes off,
the unit is calibrated
. Keep holding the activation button
during all of the following procedures.
Note: While calibrating, the Stud Sensor 50 must not
be placed directly over a stud, dense material such as
metal, or over a wet or newly painted area, or it will not
properly calibrate. If the Red LED stays lit, move to
a different location and try again.


2) Slide the Stud Sensor 50 slowly across the surface
in a straight line. As it detects a stud edge, the red LED
will go on.
Use the handy pencil notch located at the top of the
unit to mark the stud edge.

3) Repeat the above steps from the other side of
the stud. Coming from the opposite direction, mark
the other edge of the stud. The midpoint of the two
marks indicates the stud center.

Cautions on Operating
The proximity of electrical wiring or pipes to the surface
of the wall may cause the Stud Sensor 50 to detect
them as studs. You should always use caution when
nailing, cutting or drilling in walls, ceilings and floors
that may contain these items. Always remember that
studs or joists are normally spaced 16 inches or 24
inches apart and are 1-1/2 inches in width. To avoid
surprises be aware that anything closer together or of a different width may not be a stud.

I hope this helps & good luck!

DYI Stud Finder


If you don't have the cash to shell out for a new stud finder, or just don't feel like heading to the store for a single item, try this little trick instead. Get a strong magnet, the stronger the better, and gently run it over the wall you want to find the studs in. Your magnet will be attracted to the metal screws, showing you right where your studs are. If you have a weak magnet, then tie it on a string and hold it by that. You'll see the reaction rather then feel it. If your using an old neodymium magnet from a scavenged hard drive, you'll feel the very obvious tug whenever it reaches something metal.

A little searching showed I'm not the first person to think of this, but it's not a trick that's been broadcast very much. Most of the time a search for "finding a stud without a stud finder" will get you results that tell you to tap the wall and listen for the echo. That trick doesn't work with all walls, or even all studs. So next time, grab a magnet.

How to operate a stud finder


Hi There,

Sometimes the LED type readouts on stud finders aren't as intuitive as one would hope. This will help clear up what you are seeing.

There are usually four LED's and a button on the device. The LED's indicate an increased density in wall, but increased from what? Each time the unit is used it needs to go through a short calibration to get a frame of reference.

This is the procedure:

  • Place the unit flat against the wall.
  • Press and hold the button.
  • The LED will come on for a second or two then go out.
  • Slowly move the unit laterally until the LEDs come on again. You're getting near a stud.
  • When they top out (all four lit), that is the beginning of the stud. Mark it.
  • When they start to go back down, that is the end of the stud. Mark there too. The stud should be between the marks.
That's about it.

It beats knocking on the wall or drilling test holes.

Best regards
Mike

Can i mount a 50inch phillips tv on the wall model number 50pfp533/37


Yes...My 50inch plasma is mounted on the wall; has been for four years. You must be sure to screw the bolts for the wall mount which will suppport the TV are in the middle of the studs. you can get a cheap stud finder at home depot from under $10.00. It's usually only four bolts to screw into the studs and you're set.

How do i callibrate a draper 63401 detector.regard.


I have never met a stud finder that needed calibration. They should auto calibrate when you begin to search for a stud. Recalibrating is starting the search again. Start in a different location on the wall to get a different calibration. This particular stud finder has bad reports on amazon.

I have plaster walls in an old house the stud finder just keeps beeping how does this thing work?


Your stud finder keeps beeping because old plaster walls have lath boards behind the plaster that are attached to the studs and running horizontally. Try adjusting the sensitivity of the stud finder by placing it on the wall and turning the sensitivity down until it just stops beeping. Then move it back and forth in a wide enough arc to be sure that you have crossed a stud, turning up the sensitivity ever so slightly until you get a tone when you cross a stud. Hope this works out for you.

I need calibration instructions


This unit is self calibrating. There is no method for manually calibrating this tool. Just hold the sensor flat against the wall and depress the button. After a few seconds the unit is calibrated and you can begin sliding it smoothly across your wall to detect studs and wires.

I have a 9-volt Strait-Line Stud Finder with 3 red LEDs and 1 green LED at the top end to mark the Stud Edge. I would appreciate it if I could receive step-by-step instructions on how to use the stud...


I suspect there are several models but I have one model. 1) Turn on the unit (if the green light is blinking replace the battery). 2) Calibrate the unit by holding it flat against the wall for 5 seconds until the red light goes off and the beep stops. Make sure you do not move the unit during the calibration or position the unit over a stud (try a spot 6-12" away from the corner of the wall - most studs are on 16" or 24" centers and the wood/metal stud is 1 1/2" thick). If the unit keeps beeping or the red light doesn't go off during the calibration, move the unit sideways 5-8" in case you are above a water pipe or other reason for "too deep a surface" for the unit.

3) Do not lift the unit off the wall or you will need to recalibrate it. Slide the unit across the wall. When the upper red light comes on and the beeping starts, that marks one edge of the object in the wall (stud). Continue until the red light goes off and the beeping stops. Mark the other edge of the stud by moving the stud finder in the opposite direction and marking when the red light comes on and the beeping starts. The center of the two marks is the center of the stud for securing anything to the wall.

If the beep persists over a 6" range, I'd check if you have any old cast-iron pipes or a door/window that was relocated in that wall. Repeating the test in a few places vertically along that spot of the wall will tell you there is a consistent large object in that location. Neither a filled in window or door will run the entire length of the wall but you could be finding the headers (the vertical framing of the opening would probably be ~4-6" wide (double or triple stud depening on the needs of the house design)).

I hope this helps.

Cindy Wells
(on another stud-finder that I borrow, you press the buttons on the right and left side to turn it on. Calibrate by holding it to the wall for a short while and then slide it across the wall. Note when the top red led lights and the beep starts. Repeat in reverse to find the other side of the stud.)

How do I know when i am on the stud


These usually need to be calibrated in a stud-less section of the wall so that the LED just goes out. Slide the finder over the wall slowly until the light turns on--that is the first edge. Continue moving and the LED should go out--that is the second edge. These two points should be marked lightly with a pencil and the midpoint between the marks locates the center of the stud. Note that these tools will respond to wiring in the wall the same way. Hope this helps!
