WALABOT DIY 2

BOSCH GMS120 Digital Multi-Scanner

"I purchased this unit for its live wire detection. It worked well and identified every live wire during my home projects. The price, accuracy, and simplicity of use make it a must-have tool. I would highly recommend it!"

"After trying other stud finders that gave me inconsistent results, I finally bought this one. It works perfectly and quickly identifies the studs, letting me know exactly where they are. If you need a reliable stud finder, trust me: this is the one!"

"I decided to upgrade to this stud finder after using an older model. The newer model has more LEDs and is very accurate. I appreciate the integrated level, which improves my accuracy. While it requires batteries to be fully charged, I still find it worth it for the precision and performance."

“I recently upgraded to the WALBOT DIY2 for my iPhone, and it has been a game-changer for my home improvement projects. The visual interface on my phone is intuitive, providing a clear view of what's behind the walls, which gives me confidence when drilling or installing fixtures.”

“I had a short wall packed with metal studs, wiring, and plumbing. Using the Walabot, I found it effective on plain drywall, but it struggled with wainscoting. Still, I would emphatically recommend it for drywall surfaces.”

“At first, I was frustrated because it was disconnecting a lot. However, after switching to my Samsung S23 Ultra, it worked very well. It effectively showed the studs, wires, and pipes, making it a valuable tool for DIY projects.”

"I received mine with a red mark indicating damage. It detects metallic objects, but the electric sensor doesn't work. When I plug it in, it recognizes the outlet, but it fails to detect hidden wiring. I ordered a second one, and it arrived in the same condition. The non-slip elements on the back look scratched, as if they were previously used. I need to request a refund."

"I've used it a couple of times for home repairs. It's really practical, and I think it's worth it."

“This unit is large, and while it works great, I found it tricky to use in tight spaces. I had to place cardboard underneath for smooth operation. The previous detector I used had a fuzzy Velcro side, which worked better on textured walls. However, this unit accurately detected studs and even identified a pipe/wire that I could've drilled into. It definitely saved me from a potential mishap! I also noticed it doesn't attach to my phone as some demos suggested, which was a bit misleading. I would’ve preferred a better indicator for locating the center of the stud. The app is seamless to connect with, and I enjoyed the expert mode. Overall, I highly recommend this unit!”

“I really wish it didn’t need calibration every time I use it, but aside from that, it’s a fantastic tool.”

“I've tried various stud finders before, but none worked as well as this one. It's absolutely fantastic and performs great!”

"I highly recommend this stud finder. It helped me find studs effortlessly and has been essential for my projects."

"After researching various brands, I decided to try this one. It performed flawlessly, providing accurate readings where my old one failed."

"I had a big remodeling project and upgraded my old stud finder. The display is nice, but it didn't outperform my old one significantly."

"I had a commercial job and needed to locate studs at 20 locations. WALABOT hit 20 for 20, pinpointing wood studs for my wall fixtures. I'm really happy with my purchase!"

"As a tech enthusiast and DIYer, I was excited about this device, but it turned out to be a mixed experience. The accuracy was off for my new construction walls, and I found the calibration process annoying. After trying all features, I was left feeling disappointed."

"I had been wanting one of these for years, and now that it works with iPhone, I was eager to try it. It finds hidden items behind walls, but I find the professional mode unclear. Calibration is a hassle, and I wish it had a built-in screen."

"Don't be swayed by negative feedback; this product works great! It even has clear instructions on how to use it right on top."

"I've tried various stud finders, and this one fits perfectly in my Kline tool pouch while performing extremely well."

"While it does work, I've found it can be a bit inconsistent at times, so I wouldn't fully recommend it."

“I’ve tried several stud finders, and this one is by far the best. It works accurately and detects edges, even different size studs. Plus, it comes with a screwdriver and battery, which is a great bonus.”

“When I bought this stud finder to hang a shelf, it did its job well. However, there’s a bit of a learning curve with all the features. I had to adjust the device several times to get accurate readings, but it ultimately saved me from making unnecessary holes.”

“I really appreciate the accuracy and ease of use. The beeping feature when finding a stud is fantastic. It’s lightweight, making it accessible for anyone, and I’d definitely recommend it!”

"I usually don't write reviews, but I have to share my experience. This stud finder worked great when I needed to mount a TV. It was straightforward to use and very accurate, saving me from making unnecessary holes in the wall. Definitely a worthwhile purchase!"

"After using many stud finders over the years, I can confidently say that this one is my favorite! It reliably pinpoints the center of studs, which is a huge improvement over my old one. While I did notice the voltage indicator didn't seem to work, the overall functionality of the tool is impressive."

"I was pleasantly surprised by the performance of this stud finder. It accurately identifies stud locations behind the sheetrock and even confirmed the spots I found with a magnetic stud finder when I was installing grab bars in my tiled bathroom. I'm very satisfied with this device!"

"I bought this to replace my old stud finder that I had for 20 years. It's basic, but it works well. This one finds the dead center accurately, eliminating guesswork. If you want something better, be ready to spend $200. Great for homeowners or handymen looking to hang artwork or TV mounts."

"Recently, I purchased this stud finder, and it has exceeded my expectations. The setup was straightforward, and the instructions were clear. It accurately detects studs behind drywall, and I love the LCD display that shows the exact location. I tested it on several walls and it was spot-on every time. The ergonomic grip makes it comfortable to hold, and the battery life has been excellent so far. If you’re a DIY enthusiast, this tool is a must-have. Highly recommended!"

"So glad I chose this stud finder. It shows where the studs start and end, also pinpointing the center of the stud. It can also find electrical wires and metal studs. Such an awesome product!"
