| Spectra Precision LL300N-CR72 Laser OVERVIEW |
The Spectra Precision Laser LL300N package is your complete medium-range, high-accuracy solution. Ideal for basic slope work such as driveways and ramps, checking or leveling elevations, concrete forms, footings and foundations for small -and- medium sized jobs, and for excavations, digging footings and septic tanks.
The Spectra LL300N 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-feet directly onto concrete, or up to 5 feet when pushed over on a tripod means less downtime and cost due to damage caused by accidental drop or tip-over and lower repair costs over the life of the product.
The Spectra LL300N's fully automatic self-leveling capability provides fast, accurate setup. Rechargeable Ni-Cad battery pack or alkaline batteries keeps the unit working with no downtime due to power loss. Single cross-axis manual slope mode with cross-axis self-leveling allows grade matching for basic slope work, while maintaining accuracy in the cross-slope. |

| CR700 Multi-Use Laser Receiver / DETAILS - Included with the LL300N-CR72 Package |
|
The CR700 has the same “light bar” technology that is included in HL receivers and delivers extremely accurate and consistent results. Super bright directional LEDs are ideal for entry-level machine grade display that provide instant grade information to the operator and eliminates the need for a rod man in the trench.
Spectra Precision CR700 combination receiver - a step ahead in receiver technology
The CR700 includes a clamp to attach to a Grade Rod. It has the same "LIGHT BAR" technology that is included in the HL-Receivers and will deliver extremely accurate and consistent results.The CR700 can also be attached to Machinery with the included new Magnetic Mount, which is 25% stronger than the CR600 Magnet Mount resulting in stable machine mounting and a reduction in errors. With the Super Bright Directional LED's, the CR700 is ideal for entry-level machine grade display, specifically on mini-excavators and backhoes.
For any application, the industry-leading 10-foot drop Guarantee and 3-Year Warranty confirm that the CR700 is the most reliable and robust receiver available.
The World's Best Laser Receivers
Spectra Precision digital readout receivers are simply the best laser receivers - without peers in accuracy, performance , reliability and warranty. The patented "LIGHT BAR" Technology provides more accurate and more consistent readings than traditional methods. This unique technology has fewer electronic components resulting in the most rugged and reliable laser receiver available.

CR700 Combination Laser Receiver Unique Functions:
- LARGE 5-INCH RECEPTION HEIGHT - More Data / Information from the Laser
- Bright LED Arrow Displays - Turn your head when you first turn on the CR700 because the new Red/Green/Blue LED arrows are super bright and visible in all conditions.
- Magnet Mount for Machine Mounting - the NEW C71 Magnetic Mount is 25% Stronger. It will not slip on the machine no matter how rough the work is.
- Light Bar Technology - Patented Laser Reception Technology delivers the most accurate, consistant and reliable performance
- Laser Radio - the CR700 is radio-compatible with the GL412N, GL422N, GL612N, GL622N and HV302 series lasers. This enables the use of time saving functions such as Grade Match, Fingerprinting, PlaneLok and Axis Alignment.
- IP67 - Dustproof, Waterproof, Weatherproof
- 10-foot Drop Guarantee - almost destruction proof, extremely robust, eliminates downtime
- Digital Readout - Pair the CR700 receiver with an HL760 receiver to be used as a remote display - useful for machine operators and site supervisors.
- Fingerprint On/Off - a menu function allows the CR700 to enable or disable Fingerprinting
- Backlight - to view the laser receiver in the dark.
- Vertical Drift Alarm - When using lasers in vertical mode, after setting up your line, let the laser receiver warn you if the laser has been disturbed.
- 3-Year Warranty - competitors are not even close on laser receivers.
