Right now Bosch, Dewalt and Milwaukee all make a radar stud finder. But these do way more than find studs. Some can even see rebar under six inches of concrete. They are large and expensive units.Typically used by professionals on commercial projects. Probably over kill for the standard home owner. Here is a brief description of each and then a comparison chart at the bottom.
Bosch D-tect 120 reliable radar technology delivers great accuracy on wall, panel or floor. No need for a back-and-forth motion because it scans as soon as it’s on the wall or surface. Detector is easy to use in small spaces and features an ergonomic design. Because the Bosch D-tect 120 never needs calibration, you can focus on the job without worrying about the detector. Three modes ‒ studs, universal and concrete ‒ make this the right detector for more jobs. Device offers sound with light to show user when something is detected behind a wall, panel or under flooring.
Bosch D-tect 150 the future of detection technology – Precision of the highest order. Give yourself an advantage. Accurate detection of all materials including plastic due to state-of-the-art ultra wideband radar sensor system. Detection accurate to the millimeter due to ultra wideband radar sensor system. Objects are indicated by acoustic and visual signal. Maximum measuring depth of up to 6 inches (15 cm). Digital display of material properties and permitted drilling depth. Features: Detects ferrous and non-ferrous metals, electrical cables, wooden beams, plastics such as floor and wall heating pipes Intuitive user interface using multilingual menu with specific modes for different applications Easy-to-read, large, illuminated display Robust design for tough demands on the construction site: dust and splash protection of IP54, also remains fully functional after being dropped from a height of up to 1 m Requires no calibration
