Rated 4.1 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by Great Addition to The Line-up Received a replacement after problems with the first one and the new one works great. I like the fact that you can select the depth because it gives more control and accuracy. I switch between 1/2" and 1" and am able to dial in to get the most accurate results. The A/C detection seems to work accurately as well. This finder does not have center finding ability but I would trade accuracy for that feature any day. The V groove on top allows you to mark the edges of the stud and it's no problem from there. I own several other Tech 4 products and the long life of the lithium battery plus the ability to switch the batteries around gives me great flexibility depending on what kind of job I am doing July 4, 2012
Rated 4.0 out of 5.0 by Excellent Unit that has screen viewing difficulty I found the Tek4 stud finder an excellent stud finder without the complexity of other pro models. However reading the screen was like viewing the old projector TVs where you need to be at the same level and directly in front of the screen. In fairness it could be that I wear eye glasses with bi-focal s. None the less I had to return the unit because I couldn't read the screen without a lot of maneuvering. If the unit is updated for indirect viewing like others on the market and the price comes down a bit I would certainly purchase another unit. January 12, 2011
Rated 3.0 out of 5.0 by Just Okay Got this at a clearance price, and glad I did not pay more. It works okay, though the display can be difficult to view. Does find studs okay, but expected higher quality at the price this normally goes for. May 19, 2014
Rated 5.0 out of 5.0 by Does what it is supposed to Really like this product, it works like it should. I have found this device to be very reliable and that is all I want it to be. I have three other models of stud finders and I have been very frustrated with them. This product works very well and even detects live wires, however i find it to be a little on the sensitive side for AC wires. All things considered I would highly recommend this tool.

Rated 5.0 out of 5.0 by Works as described Bought this for a project and it worked as indicated in instructions manual. Was more expensive than other models, but wanted something reliable. When I bought it, it came with a free MP3 player sold for $70 at home depot, so I decided to go with this. The mp3 player doesn't compete well against other mp3 players, but can probably take more of a beating than the others. It doesn't find the middle of the stud for you, but gives you a way to mark the edges of the stud with a pencil. It doesn't beam a light on the wall like the other brands indicated, but not necessary because it has a place to put your pencil to mark the wall. Also, test the wire finder near some light switches. When the light switches were turned off, it showed that there was a AC wire, when it was on, it showed a lighting bolt indicated a live wire. I'm satisfied. A lot better than banging on the walls to find areas where studs are, but accurately finds the edges of the beams for projects that require more accuracy. September 26, 2010
Rated 4.0 out of 5.0 by This product lists great features Given the Brand Name and the price, I was expecting this unit to deliver better than average performance. This was not the case. Locating Studs using the RP4050 was less than optimum. November 8, 2011
Rated 5.0 out of 5.0 by Works great This was just the tool I needed. Excellent value. Always find the right tool when I need it. Even if I do not know what it is called at the time. November 8, 2011
Rated 2.0 out of 5.0 by Fair Poor view in display didn't pick up electric lines. I expected better. February 28, 2012
