It’s pretty hard to find a good, reliable scanner. Bosch has a twist on their D-Tect 120. This scanner uses radar which is far more consistent. The problem with radar is these tend to cost a lot of money, upwards of thousands of dollars. However Bosch found a way to give you a radar scanner for far less, about $250. One cool feature is this is calibration free. Just turn it on and go, no more waiting around. The unit will detect multiple objects such as plastic pipes, wires, rebar and more.
Bottom line, this is accurate, well priced, easy to use and dependable. If you’re looking for a true scanner, this is a great buy.
