The Spectra Precision® FOCUS® 8 Total Station offers the power of a Windows CE operating system and world class Spectra Precision Survey Pro field software combined with clear-to-view quality optics, smart design, and superior components that your surveying jobs demand.

The Spectra Precision FOCUS 8 has intuitive Survey Pro on-board software that is easy to use, and has a large display that makes data management simple.

Touch-screen technology also improves data workflow speed to access menus and software modes for fast every day data management. The Windows CE operating system supports a full alphanumeric ‘pop-up’ keyboard helping users to enter data quickly and accurately.

Built tough for use on your everyday work site in all degrees of dust, dirt, and weather conditions. The large graphic display uses features such as different font sizes, icons, and pop-up menus to make the on-board software system intuitive and easy to learn for maximum efficiency.

Use the FOCUS 8 to reliably measure and save all your topographic and staking needs. This solution includes key features such as:

     • Quick Coding: for lightning fast feature coding
     • CoGo: for your in-field calculations
     • Fast Measure: configure keys for one touch measurement

All FOCUS 8 models support Bluetooth communications to external data collectors. In addition, all models come standard with a traditional optical plummet which can be upgraded to a laser plummet. Move your data fast and easily using a USB memory stick.
