      Q:I just purchased th ProSensor M70 and it works perfectly on some walls. On all my outside walls or walls underneath windows, all the lights stay on the entire length of the wall. I've tried going slower, etd. What am I doing incorrectly?

      1 Answer
      Answer This Question

      A:  None of our units can read through side-paneling of exterior walls. There is most likely a stud surrounding the window which is why all the LED's are coming on. Ensure you are holding the stud finder correctly by the handle.
