FNIRSI Stud Finder Wall Scanner - 6 in 1 Electronic Wall Wood Stud Finder, Wall Detector with Updated Positioning Hole for Center and Edge of Wood AC Wire Metal Studs Joist Pipe

I just learned of FNIRSI a couple weeks ago from an ad for a cordless soldering iron. While browsing their site, I saw that they made a number of devices, including this stud finder. Not that my old ones don't work per se, but they're strange about batteries, and a little finicky especially on studs that aren't directly behind the drywall, (such as framing in the garage that has a layer of foam insulation between the drywall and framing.) I've tested this in a number of different scenarios and it's been dead on every single time, at about a third of the cost of my "high end" finder. I'm anxious to try some of their other offerings as they're all affordably priced. This even came with a case which none of my others included!

Excellent product. I've been using it these past few days, and it's perfect and highly recommended 👍

Works as advertised. Can find studs fairly reliably. I used it to find studs to mount holders for my bikes. I used it on my ceiling to find a decent spot to put a hook in to hang a plant from. It indicated it found a solid spot, but after putting in the hook, I found just dry wall. Still, easy to use and like the rechargeable battery.

Detector fácil de usar y preciso lo recomiendo

I think it works

I used this to find rebar on a pool demo. My heavy backhoe-mounted hammer has trouble with hard reinforced concrete. (Its old, and dad must have used 5-sack+) I started using cut-off saws, but it took awhile to figure out the right blades, and the horizontal and vertical cuts in walls are tough with heavy saws. We were kicking around ideas after dropping the first wall. "Rebar sensor". So I looked around and found this, at 1/2 price of the Bosch. I know the rebar pattern from the first wall and was looking for it on the second. I have hit rebar with a concrete drill bit on every rebar it located. (I wanted to find them with a cheap bit that would stop) I have a total 90' perimeter with 68' left. Rebar cutter sds+ drill bits are coming, a 6" rebar/concrete bit is only $12. Only using a little water (a must with saws unless you don't care) basic titanium some carbide? bits have done about 25 4" max with little wear. They go right through concrete @ 5/8 & 3/4. My bit cost looks a lot lower than my blade cost. I have a 12T jack to knock the wall over, I used the loader/backhoe to knock over the first. We will see if this tester found enough rebar to push wall 2 over. I put in extras hole between the #3 rebar @14 and never hit rebar. I'm optimistic at this point, a good low-price tester looks to have made a hard a lot easier. I have #3 at 2.5 up to 4" inches deep to the outside edge. About accuracy, 1 cm = 0.39", 12 cm =4.65". On the cut wall I tried to determine the depth accuraccy, It measured nearly 4" on a 2.5" to edge 3bar. Could be my math but it didn't look right. I'm confident it will find rebar at least 4.25" inches.

el mejor escáner que he probado soy handyman, he comprado varios pero este me sorprendió por su precio, he comprado otros mas caros y no sirven como este modelo, lo uso todos los dias, en drywall, concreto, madera y funciona de maravilla

Even after calibrating, it still didn't work right and couldn't accurately locate the studs. We had better success just using a magnet.

excelente, finciona muy bien

Works really well. I tried a cheaper detector but it was very hit and miss finding the wooden batons in the stud wall.

not a SaM product

Been using it for a while now and though it does fund the studs, it also shows electrical sign though there was no electric wires behind the wall which made me alot doubtful while working on walls with electrical wirings so not recommend it.

Lo poco que usado si ha cumplido 👍🏼
