Our fastest, highest-accuracy Construction Layout solution

Spectra Precision Focus 35 Total Station: Productive, Reliable & Affordable

Focus 35 total station for construction layout

Spectra Precision Focus 35 robotic total station

The Spectra Precision FOCUS 35 is a robotic total station providing high speed, accuracy and precision in measurement in 1”, 2”, 3” or 5” accuracies.

With the FOCUS 35 the speed of observation and precise positioning is provided by patented StepDrive™ motion technology, which controls the horizontal and vertical motion of the motors, eliminating the need for traditional motion locks.

The FOCUS 35 includes a tracking sensor that uses LockNGo™ FastTrack tracking technology, enabling the instrument to constantly lock onto the prism.

For contractors, Spectra Precision Layout Prosoftware and the FOCUS 35 together offer the convenience of carrying, managing, editing, and laying out your job site blueprint while you are on the go.

This combination is a critical tool in the field of construction layout and is designed to make the layout process more productive, accurate and reliable.

Layout Pro guides the layout of major points, adds string dimensions on the print, and calculates diagonals and angles.

If you’re looking to achieve significant gains in productivity, accuracy and reliability, look no further. Email or call 800-243-1414 to schedule an on-site demonstration.

Dual-laser systems for interior Construction Layout

“X marks the spot” to simple Interior Layout with the Spectra Precision QML800G laser system

Download the Spectra Precision QML800G datasheet
QML800 for construction layout

Spectra Precision QML800 dual-laser system

The QML800 can locate points in 5 seconds. Other features include:

  • Typical accuracy of 3 millimeters (1/8th of an inch)
  • Working range of 30 meters by 30 meters (100 feet by 100 feet)
  • Visible distance of 22 meters (70 feet)
  • Self-leveling range +/- 4 degrees from level
  • Estimated labor reduction of up to 50%
  • Quick payback, with ROI typically realized in 1-3 jobs


This two-laser system improves the accuracy of interior layout – even on complicated shapes, arcs and curves – and generates a visible X to mark the spot. The lasers communicate wirelessly with an easy-to-use Android tablet. With no measuring required, calculation and tape-reading errors can be eliminated, and errors are not compounded from one marking error.

The QML800 system is useful for drywall contractors, MEP contractors, general contractors, construction managers and architects.

The Spectra Precision QML800 QuickMark Layout system is composed of two lasers that communicate in wireless mode controlled by an Android tablet. The system calibration consists of aligning the two lasers together and defining an origin point and a scale.

Our highest-accuracy 3D Scanning solution

Trimble TX 3D scanners offer the right range and right price for nearly every need.

Trimble TX series 3D Scanners

Trimble TX series 3D Scanners

Both models share an impressive range of key features.

  • Fast, high-resolution scans in as little as three minutes.
  • Wide 360-by-317-degree field of view.
  • Data accuracy, clarity and richness with high-density 3D point clouds.
  • Fast image capture to colorize scans with VISION™ technology.
  • Intuitive and easy to operate.
  • Data integration with Trimble survey instruments and Trimble Realworks software.

A key difference between the two models is range. The Trimble TX8 maintains its high precision over the entire range of 120 meters, with an optional upgrade that extends the range to 340 meters. The Trimble TX6 operates at a range of 80 meters, with an optional upgrade to 120 meters.

Using Trimble’s patented Lightning technology, each model captures precise data at high speed over its full measurement range. And since Trimble Lightning technology is less susceptible to variations in surface types and atmospheric conditions, you can capture complete datasets from each station.

Setting new standards for performance and ease of use are two Trimble® laser scanners – the Trimble TX6 and the Trimble TX8. Both offer high-speed collection of 3D data, but with a slightly different range and other key features.

The Trimble TX6 laser scanner is a cost-effective solution with a wide range of uses for building information modeling (BIM), virtual design construction (VDC), quality control, preservation and restoration, plant and industrial measurement, and public safety and forensics.

The Trimble TX8 combines speed, long range and precision to deliver high-quality results for civil engineering, surveying, plant and industrial measurement, mining and quarries, building and commercial construction, deformation monitoring and many other uses.


  • Color touchscreen display and one-button scanning make data capture easy and efficient.
  • Intuitive interface lets you quickly manage scan resolution and define scan areas.
  • Operate the scanner remotely with a Trimble tablet or other mobile device via integrated WLAN.

To colorize scans, an integrated camera can quickly take full field-of-view HDR images in just two minutes from each station.

These laser scanners streamline work in the office with clean, low-noise data that reduces processing time. Data loads directly into Trimble RealWorks® and Trimble Scan Explorer, enabling project collaboration via Internet Explorer. Paired with RealWorks, these scanners also provide efficient data flow into popular CAD programs, Trimble EdgeWise and SketchUp, for point cloud modeling.

Designed for mobility, each scanner weighs just 11 kg and is powered by lightweight, long-life lithium ion batteries.
