The inclusion of a live wire meter adds an important safety feature, making it safer to use when drilling into walls.

The wide LED display that shows the full width of studs simultaneously is a useful feature, allowing for a clear and comprehensive understanding of the stud's location and size. It can also auto-adjust for depth, material, and texture up to 1.7 inches, which can be very practical for various wall types and conditions. This makes it a versatile tool for construction, renovation, and DIY projects.

The device operates on two AAA batteries, which might need frequent replacements depending on usage. At 11.4 ounces, it is relatively lightweight and easy to handle.

The BOSCH GMS 120 Wall Scanner is a versatile tool designed to detect wood studs, metal objects, and live wiring within walls. One of its major strengths is its multi-mode detection capability, allowing users to switch between different detection types easily. The illuminated ring that indicates detection status is a helpful visual aid, changing from green to orange to red based on proximity to an object, which simplifies the detection process for users. Additionally, the automatic center finder feature is beneficial for pinpointing the center of detected objects, making it highly accurate.

Users will also appreciate the illuminated graphical display that clearly shows mode, detection strength, and other information, thus enhancing usability. The audible detection signal adds another layer of convenience, with the option to turn it off if desired. The package includes a 9V battery, hand strap, and pouch, adding value and convenience for the buyer. However, the product does have some drawbacks. At 0.5 kilograms, it may feel slightly heavier than other models, which could affect prolonged use. Its dimensions (6.5"D x 10.25"W x 3"H) are relatively large, making it less portable.

There is no connectivity technology, which means it can't be synced with a smartphone or computer for data logging or enhanced functionality.

The WALABOT DIY 2 is a high-tech wall scanner and stud finder that connects to your smartphone, allowing you to visually identify the center of wood and metal studs, as well as track pipes and wires. One of its standout features is its ability to display images of what's inside your walls on your phone, rather than just relying on beeps. This can make it much easier to understand what you’re detecting. It can detect objects up to 4 inches deep, which is quite impressive and should suffice for most home improvement projects on drywall.

However, it's important to note that this device only works on drywall and should not be used on lath & plaster, tiles, or concrete.

It is compatible with both iOS and Android, making it accessible to a wide range of users.

On the downside, if you are looking for a stud finder for use on various wall types, this might not be the best choice. Additionally, the reliance on smartphone connectivity means that if you're not comfortable with using your phone for such tasks, you might find it a bit challenging.
