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 de-

signed for use in harsh, loud construction environments.

Impact resistant housings, recessed windows, water-

proof design, attached battery doors, durable battery

contacts, and a high volume beeper are incorporated into

every detector.
