Stud Finder, Preciva Wall Scanner-8 in 1 Multifunctional Wall Detector with 6 Modes & 2 Functions for Studs, Wood, Metal, and AC Wires Detection (9V Battery Included)

Good

Use this anytime I need to find stud, very accurate.

We got this because we were moving into new apartment and landlord ok’d shelving so we needed something that would help us find the studs and also avoid damaging any wiring in the wall. It’s finds studs easily and effectively but the electrical sensitivity is not effective even when being held right next to a plug with known wiring does not pick up on it.

Works perfect

Seems like a decent stud finder. My main beef is I'm always skeptical when I receive an item that is not in a factory sealed box, and\or item does not have obvious signs of being new. Such as lens\display protector screen or the such. Did I just get sent a used\returned item that I paid new prices for?Found rafter in ceiling easily enough, did some quick testing with the AC mode, only way I got a hit was when I scanned external wire to device. Metal mode seems to work decent enough.

Ok

Had high hopes for the Preciva Wall Scanner Sensor -4 in 1. I am an engineer with over 40 years of electro-mechanical experience. I have used numerous stud finders in my life but this one is the worst. I had some book shelves to install so thought I would give this a try. Read and followed directions. I tried the "stud" setting first and after several sweeps of not finding anything (Yes, I did calibrate in a known dead zone, and no, I did not move it away from the wall after calibration. Yes, I did keep the button pressed the entire sweep), it started giving some readings that I marked with a pencil. Some were only a few inches apart. Many were scattered over the wall. Next, tried the deep setting. Well this found different locations for what it thought were studs. Finally decided to try the metal setting, hoping it would find the drywall screws. Again it "found" several but nowhere near the "stud" or "deep" locations. After 20 minutes I had about 30 markings on the wall, some near each other (within a 5" circle) many no where near each other. Finally went down to the fridge and grabbed a neodymium magnet my wife used for holding pictures. It found all the drywall screws in about 5 minutes, all in rows indicating stud locations and also no where near any markings the "Preciva Wall Scanner Sensor" though they were. This piece of junk is going back.

My old stud finder finally died. I'd had it since the 1980's and I thought it worked pretty good. Now that I have this new stud finder I wish I had bought something like this a lot sooner. I've tried all of the settings and I find this to be very accurate. I just used it so I could mount a fire extinguisher, which is very heavy. I needed accuracy so I could get all four screws into one stud and it worked as advertised. What else can I say about this stud finder? It's easy to use. It is very accurate. And unlike another user that condemned this as poorly built and that he had to wait a few seconds for it to calibrate itself, I really like it. He should have returned it for a replacement if he had a problem. However, some people are never happy. He even knocked it because it is purple? Really? I like the purple color. It doesn't clash with the colors of any of my rollaway tool boxes, LOL. That in and of itself is a good indicator that that guy is never going to be happy. Anyway, I am very happy and I am going to buy one for my son and my son-in-law. Just buy it and try it. You will like it.
