1. DO NOT shine or aim the laser pointer at people or animals, as it may cause damage to
eyesight.
2. The combined stud/distance detector is a precision instrument which must be handled with
care.
3. Avoid shock, vibrations and extreme heat.
4. Avoid dust and water, which may obstruct the lens. If needed, use a soft cloth to clean the lens.
5. Keep the laser tool dry and clean.

OPERATION AND USE
- STUD DETECTOR: (FIG.2)
Place the detector flat against the wall. Press
and hold button % to calibrate the unit. The
buzzer will sound to confirm and the display
will read 'Stud'.
NOTE: If by chance, the calibration is carried out
too close or over a stud the detector will never
pick up any readings, and give false
information. For this reason it is advisable to
take a couple of readings and calibrate the unit
in different positions to ensure accuracy.
Upon detection of a stud or nogging the bars
will begin to increase in the LCD display and the
buzzer will sound when all twelve bars are lit.
The best method of accuracy is to mark the wall
at the point where the buzzer has sounded.
Then move the detector approximately 30cm
past this point. Trace back with the detector
again, until the buzzer is sounded. Mark the
wall, and the midway point between the marks
is the centre of the stud/nogging.
NOTE: The wall must be a cavity design for the
detector to work correctly. If the cavity has
been filled with glass fibre, even this may effect
the readout.
- DISTANCE DETECTION: (FIG.3)
Ensure the detector is positioned and pointing
perpendicular to the target area. The laser is a
guide to where the measurement is being
taken.
The target area must be a rigid surface without
any irregularities. The target cannot be
impaired by obstacles.
For more accurate results and when measuring
longer distances ensure the target area is large
(measurements over 12M the target should be
>3M2). For small and irregular surfaces try
affixing a piece of board as the target area.
The ultrasonic distance detection will not
measure through glass, but WILL measure to
glass.
Measure from base (i.e. measurement includes
length of detector).
Press button & to select metric or imperial
results.
