Versatile,
accurate and easy to use for a range of grading and excavation
applications
 The versatile Spectra Precision Laser CR600 receiver is
designed for use by general, concrete and site prep contractors. It
is an easy to use tool for accurate measurement of elevations across
the site – and is ideal for use with the LL500
transmitter.
The CR600 can withstand harshest conditions on the construction
site. It has a rugged, waterproof, lightweight magnesium housing
capable of withstanding a drop of up to 3m (10-foot) on
concrete.
 The CR600 can be used as a hand-held or rod mounted
receiver for a wide range of applications, including measuring cut
and fill, leveling forms and footers, setting grade and measuring
elevation changes. In addition, the CR600 can be used as a machine
control mounted receiver for use on a backhoe, small excavator or
skid steer loader. The CR600 is an ideal low-cost entry to machine
control productivity.
With its 15-channel linear display, it does not require the
operator to be ‘on-grade' to measure, as the high and low indicators
allow the offset to the on-grade position to be directly measured.
Moving outside of the receiver pickup area, the lost beam direction
indication allows contractors to quickly recover the on grade
position.
The CR600 is visible across the jobsite. The super-bright red and
green LED elevation indicators ensure high visibility in poor light,
at a distance and at an angle. Wraparound receiver cells with
continuous pick-up through an operating range of 270° mean less
setups and improved productivity, especially for machine
applications.
