Review on VIVREAL 4 In 1 Stud Finder Sensor Wall Scanner - LCD Display, Sound Warning & Auto Calibration For Wood AC Wire Metal Detection by Anthony Rael

i had never had the need for a stud finder until i purchased this one. for that matter i had never even used one before. that said i needed to install a railing in one of our staircases but with an old plaster wall i had no idea where i mount it.the instructions were good and helped get me started. after using just a few minutes i had it down and no more need for them. it found the studs easily and was very accurate. i was surprised and thankful it also found electrical wires hiding adjacent to one of the studs. if it hadn't i could have easily drilled into them and that would have made for a very bad day.this is easy to use, is accurate and helps find not only studs and wires in plaster walls but a long list of other applications. i am very glad i picked this up and have nothing bad to say about it.
