Spectra Precision DR400 Digi Rod - Rodless Grade Checker

The Spectra Precision® Laser LL100 is a complete one man leveling crew in a case. A complete system is
contained in a single hard-shelled, portable carrying case - the laser, receiver, clamp, tripod, and grade rod -
for easy transportation, storage, and use. A standard case with laser and receiver only is also available.
Featured highlights
Automatic self-leveling increases productivity with fast setups and minimal training
One person elevation control up to 500 ft (150 m) away increases productivity
Durable construction can withstand tough jobsite conditions

The Spectra Precision® Laser LL300 features a rugged design with "hard hat" rotor protection that provides
superior drop and weather protection. Built to withstand severe drops of up to 3 ft (1 m) directly onto concrete,
or up to 5 ft (1.5 m) when pushed over on a tripod means less downtime and cost due to damage caused by
accidental drop.
Featured highlights
Increases productivity with fast setups, fewer mechanical parts, and automatic self-leveling
Maintains performance even in rainy, dusty and other harsh job site and weather conditions
Durable design reduces downtime due to drops and tripod tipovers

The fully automatic, self-leveling Spectra Precision® Laser LL400 Laser Level sets a new standard in rugged
reliability, handling a wide variety of general and concrete construction applications. Even in tough jobsite
conditions, the LL400 consistently delivers reliable, accurate performance to increase your overall productivity
and cost-savings.
Featured highlights
Fast setup, minimal training time and automatic self-leveling minimize operating costs and boost productivity
Highly rugged design and unique patent-pending lighthouse seal protects the transmitter head and glass,
offering superior drop and weather protection for reduced downtime
One-person operation reduces labor costs

The Spectra Precision® Laser LL500 Laser Level is a one-person leveling system designed for longer range
measurements across your entire site. Accurate, stable and reliable, the LL500 features a 1,600 ft (500 m)
working diameter which increases productivity by reducing the need for multiple setups on a large job site.
Featured highlights
High accuracy with temperature compensation provides highly stable, repeatable accuracy even under large
temperature changes
Alkaline or rechargeable batteries keep the unit working and minimize downtime due to power loss
Self-leveling with built-in shut off for increased accuracy over the entire work area and reduced errors

Spectra Precision HL750 Laserometer Receiver

The Spectra Precision® Laser HL750 Laserometer is a highly versatile laser receiver for basic and advanced
leveling and aligning applications. It is designed for general, concrete and site preparation contractors. The
HL750 measures elevations across the site, and is ideal for use with any rotating transmitter.

The HL750 features a digital readout of elevation that provides a numeric display of ± 5 cm (± 2 inches). The
readout is displayed on the large front and rear LCD's and shows exactly how far the elevation is from
on-grade for fast and easy cut/fill readings. Accurate measurements can be made without moving the rod
clamp, saving time and increasing productivity. Selectable units of measure can be displayed meeting your
application - mm, cm, ft, in or fractional inches.

A 12.7 cm (5 inch) reception height, more than double the industry standard, allows quick acquisition of the
laser beam. An anti-strobe sensor prevents false readings from site strobe lights.

Radio communication allows working with another HL750 for long range remote display and monitoring
capability. The HL750 also communicates with the GL512 and GL522 Grade Laser for PlanLok and Grade
Matching capabilities.

Spectra Precision UL633 Universal Laser
The universal laser can provide precise automatic axes alignments to two desired points without positioning
the receivers 90 degrees perpendicular. This allows contractors to perform easily dual axis alignments for
applications such as grade work on sports fields, parking lots, tennis courts and driveways.
Featured highlights
Automatic electronic self-leveling provides fast, easy horizontal level, grade, and vertical plumb setup
Large compensated grade range from -25% to +25%
No rework due to automatic temperature and grade- and cross axis compensation
