Overview for the CST Berger CST305R 5 Second Reflectorless Total Station

The 56 CST/Berger CST302R (2-Second) Reflectorless Total Station makes measuring survey and construction sites, reconstructing crime and accident scenes, and surveying archaeological excavations easier than ever. The advanced technology of reflectorless total stations allows you to get more work done in less time by eliminating the need for a target prism at the end point to be measured.

Reflectorless Technology

The Reflectorless Total Station, however, takes measurement to a new level by eliminating the need for a prism or reflective tape. Not only does that mean you need only one person in order to get precise measurements, but it also enables you to measure to locations that were previously dangerous or time-consuming to reach. No need to worry about clambering up scaffolding, checking power line clearance, or checking the position of forms prior to a pour: the 56 CST/Berger 302R gives you accurate measurements down to the millimeter.

Pinpoint Laser Beam Accuracy

The small diameter of the laser beam ensures that the laser focuses exactly on the point you want to measure - and not the surrounding area. Broader beams can skew your data by measuring the area you want to pinpoint, as well as a portion of the surrounding area. The narrow beam of the CST/Berger Reflectorless Total Station, however, can be easily aimed through wire fences, around tree branches and telephone poles, or target roof corners with bulls'-eye accuracy.

Excellent Memory Management

With the CST/Berger Reflectorless Total Station, managing your information is easy. The internal memory allows you to store up to 15,000 points, and the external memory cards slot and included SD card enable you to store or transfer a nearly unlimited amount of information to a laptop, PC, or other total station.You can also send information to another member of your team using a mobile phone, giving you flexibility in how you use the data you gather.

Laser Pointer Function

The 2- second Reflectorless Total Station's visible laser beam can be used as a convenient laser pointer function with the press of a key, enabling setting out, interior leveling works, vertical alignment, and much more. The 30X magnification and 3 inch resolving power of the telescope, you can be assured that not only will targets look clear and sharp through the viewfinder, but that you'll have the precision you need to do the job well.

Check Status at a Glance

Check your data easily with the high-quality graphic display. Dual screens allow you to view your data from both sides of the CST302R, while the four-line LCD screen is easy to read even when standing at an angle.

User-Friendly Keyboard and Softkeys

The control panel of the CST Optical Total Station is designed to be user-friendly with large ergonomic buttons. Four softkeys quickly initiate common actions, such as setting air pressure and temperature, instrument height, and offset measurement mode. The two quick keys save time by allowing you to assign the function you choose.

Long Life Lithium-Ion Battery

The CST/Berger Reflectorless Total Station uses a lithium ion battery, which unlike the Ni-Cd batteries, permits you to fully recharge the battery without losing capacity. You also get up to six hours of continuous usage time taking angle, distance, and height measurements.

Also included are a rugged hard case for storage and transport, a CD for the downloadable software, a USB cable, and a battery charger.

Both the accessories and the main unit of the 56-CST302 CST/Berger (2-Second) Electronic Total Station combine to give you the accuracy and precision you need to save time and money. This surveying and construction tool will give you a substantial return on your investment, allowing you to focus on being a leader in your industry.
