General Description
The THUNDER family of hand-held laser detectors is
designed to receive and indicate reference elevation
information from rotating laser levels.
Model 54 is designed for general outdoor use. It has a
Liquid Crystal Display (LCD) on the front that gives a
visual indication of High, Low or On-grade. A beeper
also emits three distinct audible tones for High, Low or
On-grade. A general purpose rod clamp is included with
the Model 54.
Model 56 is designed for interior applications with visible
beam rotating lasers. It may also be used with exterior
invisible rotating lasers. It uses Light Emitting Diodes
(LED’s) on the front for grade indicators which display red
for high or low and green for on-grade. A beeper also emits
three distinct audible tones for each of the three grade
channels. A magnet is built into the top of the housing to
attach it to ceiling grids. A lanyard is included as a drop
protection device.
The THUNDER Detectors have been specifically designed
for use in harsh, loud construction environments. Impact
resistant housings, recessed windows, waterproof design,
attached battery doors, durable battery contacts, and a high
volume beeper are incorporated into every detector.

1. Power Switch and Loudness Selector - turns the unit
on and off and selects volume level.
2. Beeper Output - emits distinct sound for High, Low, and
On-grade elevations.
3. Laser Reception Window - protects the photocells which
detect the laser signal.
4. LCD Window - visually indicates the detectors position
relative to the laser beam. Also indicates power on and
low battery warning.

5. Clamp Slots - two dovetail slots accept the rod clamp.
6. Tab Slot - accepts clamp tab and locks clamp in place.
7. Offset Marking Notch - used for transferring reference
marks. The top of the detector is 1.0” (2.5 cm) above the
laser On-grade location.
8. Serial Number Label.
9. Battery Door - compression sealed battery compartment
houses 2 x “AA” batteries and ID label. Use a coin to open
the door latch and insert batteries noting the plus (+) and
minus (-) terminal diagram on the housing.

Press the power switch once to turn the detector
on. The beeper will sound and all the symbols on
the LCD will be visible. The power symbol will be
displayed to indicate the unit is on. Pressing and
releasing the power switch again will toggle through
volume selections of off, low, and high. Depressing and
holding the power switch for approximately 2 seconds will
turn the detector off. The unit will automatically shut off if
it is not used for 30 minutes.
The photocells that detect the laser beam are located
behind the reception window. This window must be directed
toward the laser to receive the beam.
When a beam is received, the LCD will visually indicate
the detector’s position relative to the laser beam. A low
battery warning symbol will appear when approximately
one hour of battery life remains.

When a laser beam is received, the beeper will also emit
audible signals. Fast beeping means the detector is too
high, continuous is on-grade, and slow is too low.
A Model 52 general purpose clamp is included with the
Model 54 to attach the detector to grade rods. To secure the
clamp to the detector, align the two dovetails of the clamp
to the grooves on the back of the detector. Slide the clamp
down onto the detector. A snapping action will ensure the
clamp is securely attached. To remove the clamp, depress
the thumb release tab and slide the clamp upward.

2. Dovetail slots - attaches clamp to the back of detector.
3. Reference Indicators - points are aligned with detector
On-grade for grade rod readings.
4. Clamping Screw - tightens the clamp onto rods and
staffs by moving the traveling jaw.

Model 56 - Operation
The operation of the Model 56 is similar to the Model 54
(Please refer to page 3). When a beam is received, the
LED will visually indicate the detector’s position relative
to the laser beam.

A lanyard clip attaches to the detector in the same
manner as the Model 52 grade rod clamp. The lanyard
may be attached to the clip and used as a detector drop

Maintenance and Safety
CLEANING: Do not wipe dust or dirt off the detector
reception window or display windows with a dry
cloth or other abrasive material as scratching could
occur, reducing visibility through these windows.
A soft cloth and mild soap and water are effective.
The unit may be submerged or sprayed with a low
pressure water hose if necessary. Do not use any
other fluids other than water or glass cleaner, as
they may attack polymer components.
TRANSPORT: Use the original carton or a laser
instrument case to transport the detector.
STORAGE: If the detector will not be used for a
month or more, remove the batteries.
BATTERIES: It is recommended to use only high
quality alkaline batteries.
INTENDED USES: The laser detector is designed
and suitable for detecting a rotating laser beam.
PROHIBITED USES:
- Operation without instruction.
- Operation other than the intended uses.
- Opening the detector, except the battery door.
- Modification or conversion of the detector.
- Use of accessories from other manufacturers.
PRECAUTIONS:
- The person in charge of the detector must understand the instructions in this manual and ensure
other users do also.
- Periodically carry out test measurements, particularly
after the detector has been subjected to abnormal use
and before and after important measurements.
