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.
