Zircon StudSensor i65 Center and Edge Finding Electronic Stud Finder

The stud finder is easy to use. Came with a new nine volt battery, just remove the insulation strap and close the cover and it's ready. No tools are needed for opening the battery compartment. Just remember to let the finder calibrate on the wall for a couple of seconds before moving it. Then slid it parallel to the studs, hold the finder straight and move slowly with finder. The finder does have an AC detection system on it for wiring on voltages of 110-127 VAC. It will show you on the LCD screen that you are a the edges of the stud and when you get to the center of the stud. When you arrive at the center you get a audible alarm and a lit pointing indicator. Now, the accuracy will vary with the wall material and thickness of the wall. On freshly painted walls it may take up to a week for it to work correctly. If you have an issue with finding the stud, you can enter the finder into High sensitivity mode. It has proven pretty accurate for me, the AC sensor was a little off on one circuit from a old baseboard heater wire that is still in the wall. I pulled all the wire out of the breaker panel years ago. Always check twice before making a hole in your wall.

This is my new favorite tool! It came ready to use with a 9 volt battery. I just painted the living room so I had to hang all my pictures and clock again. Normally I would tap and pray then patch. This ended all that and told me where the studs were. It was correct 100% of the time. It also tells you if your right/left or center of the stud. The best part it will also alert you to live wires! It has a lcd screen and beeps and lights up. Very easy to use! I'd give it 10 stars if I could...I really love this little tool!
