SELECT MODE
• Move several inches to the left or right and start
again.
• Select “Deep” stud and start again.
• Release On/Off button, move over a few inches,
press On/Off button, and start again.
• On rough surfaces, place piece of cardboard on
wall, scanning through it to help slide unit more
smoothly.
• Always hold StudTech Pro™ parallel to stud or joist
and move across it.
• Because studs are normally spaced 16 in. (406mm)
or 24 in. (610mm) apart and are 1-1/2 in. (38mm)
wide, beware of anything closer together or of a
different width.
• All modes except Deep Metal have sequential level
indicators ( bar graph) on the LCD.
• After calibration has finished,
slowly slide unit across wall
right or left. As you begin to
approach a stud, the
sequential levels on the LCD
will increase, and peak at the
stud edge for Wood Stud and Deep
Stud modes, and for Metal Stud mode. Mark this
spot to indicate stud edge.
• Continue scanning beyond the marked spot until
the peak level disappears then slide unit in reverse
direction to locate the other edge of stud. Mark this
second spot. Center of stud is the middle between
the two marks.
