The FOCUS 35 is a motorized total station providing high speed, accuracy and precision in measurement. The FOCUS 35 robotic instrument moves the power of the observer from the instrument to the range pole, improving efficiency. The speed of observation and precise positioning of the FOCUS 35 Robotic Total Station 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.The FOCUS 35 RX extended operation models feature market-leading battery life.The FOCUS 35 is available in 1”, 2”, 3” or 5” accuracies and is controlled by the Spectra Geospatial Survey Pro™ field software using an onboard Windows CE touchscreen interface. The FOCUS 35 is also designed to be controlled externally by Ranger™, Nomad™, or T41® data collectors running Survey Pro field software, Layout Pro or FAST Survey on the Ranger or Nomad. Alternatively, bring your own controller and connect to the FOCUS 35 using Bluetooth or the SPDL Radio Bridge.

The FOCUS 35 is available in three models:

  • Robotic
  • LockNGo
  • RX

All models include a motorized drive system at the instrument, and a tracking sensor to track the range pole and prism.

To maintain contact between the FOCUS 35 instrument and the remote observer with the range pole and prism, the robotic solution must include a communication link. The FOCUS 35 Robotic and RX uses an integrated 2.4 GHz radio modem, as does the Ranger 7 data collector. The 2.4 GHz radio modem provides interference-free robotic data communications.Once your robotic communications have been established you can control all the functions of the FOCUS 35 from the range pole as you move through the job site making measurements. This makes it possible for a single surveyor to perform high accuracy stakeout or topographic surveys by themselves. From high order control surveys to topographic data collection or fast-paced construction stakeout, you can rely on a FOCUS 35, even in harsh outdoor conditions.The FOCUS 35 and Survey Pro provide you with world class solutions for any surveying application. An example of these features includes a unique robotic software technology that can be used when associating the FOCUS 35 with a low-cost GNSS receiver and Survey Pro software. This combination of technologies allows the user to take full advantage of the Spectra Geospatial GeoLock™, technology to keep locked on target. Layout Pro™, software and the FOCUS 35 together offer the convenience of carrying, managing, editing, and laying out your job site blueprint. 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. For example, use Layout Pro to guide the layout of the major points, add string dimensions on the print, as well as calculate diagonals and angles.

The FOCUS 35 robotic solution is best described as Simply More Powerful. Packaged in a modern, sleek, and streamlined design, it is easy-to-use, affordable and tough. FOCUS 35 Total Stations are designed to meet all your surveying needs.***For more information on the Focus 35 make sure to check out the pictures above where we have provided you with a spec sheet regarding the Focus 35.
