Just got this Cyber Professional Stud Finder and I'm impressed that for $89 it does everything I actually need in one tool. I already have a good quality stud finder from Home Depot that works great for regular wood studs, and I confirmed that this one is equally as accurate on that front.
The real advantage for me is the multi-mode scanning. My building has metal framing in some spots and I definitely don't want to drill into any live wires. This thing handles wood studs, metal objects, and live AC detection really well. The electrical sensitivity is especially impressive. I tested it on an extension cord and it picked it up from almost a foot away.
I feel way more comfortable using this over any other stud finder I've tried. Being able to pick up on metal or electrical gives me a lot more confidence before I drill.
The back has a nice felt material that lets it glide smoothly across the wall, plus there's a clear indicator showing exactly where the sensor is. The instruction manual is actually well written and easy to follow, and it even includes links to helpful videos.
Overall this is a solid all-in-one scanner. If you need reliable stud, metal, and especially live wire detection, this one is worth grabbing especially for the price.
