Powerful Robotic Total Stations

Focus 35 Total Stations with Robotic, LockNGo, and RX Models

The FOCUS 35 is a motorized total station designed to move 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. While the FOCUS 35 RX extended operation models feature market-leading battery life.

The FOCUS 35 is available in three models:

Robotics

Use motorized drives to precisely turn and repeat angle and distance measurements.

Lock N' Go

Includes a tracking sensor to enable the instrument to constantly lock onto the prism.

RX

Offers 12 hour extended operation through a unique dual battery system.

Automated

Built-in motorized drive system, tracking sensor, and communication link for remote controls to the unit.

Unique Functionality

Increased productivity by including robotic and prism tracking capabilities.

High Performance

Built-in software and features allow for highly efficient workflows and fast data collection and stakeouts.

Accurate

Measure any prism up to over 4000 m with an accuracy of 1 mm + 2 ppm.

StepDrive™ Technology

The speed of observation and precise positioning of the FOCUS 35 robotic total station is provided by patented StepDrive™ technology. StepDrive controls the horizontal and vertical motion of the motors, so there is no need for traditional motion locks. Using the motorized drives it is possible to precisely turn to, and repeat angle measurements. This results in quick and reliable measurements which substantially increases your staking productivity.100

LockNGo Technology

All FOCUS 35 models include a tracking sensor that uses LockNGo technology enabling the instrument to constantly lock onto the prism. The benefit of LockNGo technology is the ability to follow the prism at all times and reduces downtime from not having to re-point the instrument on every observation. Additionally, LockNGo is compatible with most standard passive prisms prism, making the FOCUS 35 an ideal solution for anyone that wants to continue using accessories
they already own.

Packed with New Features

Motorized Drive System

Capable of quick and reliable measurements.

Prism Search & Tracking

Reduces downtime by following the prism at all times for faster data collection.

Remote Opration

2.4 GHz radio modem provides interference-free robotic data communications.

1", 2", 3", and 5" accuracies

Full range of accuracies to give you more flexibility on the equipment you need.

Hot-swappable batteries

Eliminate power-related downtime and ensures maximum power availability.

Survey Pro Field Sofware Compatible

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 the Survey Pro field software.
