Review: It works ! - Well it worked great I had a feeling a gas pipe in the wall exactly where i thought it said yep. So in one use it paid for itself I’d say. Played with it all over the walls found old pictures pin nails and stuff. Very sensitive. It picks up metal / wood at about 100mm away then using the three lights you then can narrow it to a pin point ? It’s good worth the purchase. Worthwhile purchase
Review: might be cheaper than most, but you still need to know what you're doing - first off, many stud and wire finders, even the high end ones are not 100% fool proof and perfect, you need to know what you are doing. I have used this to check for wires and studs in our new build. checking for studs may not give you a definitive reading, but you can expect another stud to be 40-60cm away. So if the reader thinks the centre is here with 50%, then move along, watch it drop to 0% and then again see if it goes to about the same, about 40-60cm away. Same with wires. The monitor will alert you to wires, but its never 100% certain. Use places where you know for a fact wires will be. like directly around the light switch. This should act as a control so you know what kind of readings to expect. This has served me well in a new build. I cant testify to ho well it works with older houses.

**Q: Does this work on brick?**
A: I’ve only used it to detect electrical cables behind brick, but it worked as advertised when doing so.

**Q: Can this detect ceiling joists under a carpet flooring?**
A: I wouldn't have thought so
