    Comments about Stanley® 77-720 Stud Sensor 200™:

    I used this item in a doctors surgery which had all drywalls fitted,the Stanley 200 never let me down ,located the studs and electrical wiring with ease,self calibrating too always a bonus.Apart from fitting a nine volt battery which takes all of 10seconds to do i have nothing negative to say about this product, well done Stanley Tools
