System 1200 introduces a new generation of technological breakthroughs in high-end surveying instrumentation (GPS & TPS) that further improve productivity and reliability: SmartTrack and SmartCheck GPS technology, and PinPoint reflectorless EDM TPS technology. This new generation of products offers X-Function, enabling productivity gains to be realized from the first day.

X-Function facilitates the working together of TPS and GPS instruments through harmonized design in all facets of the system. Through an easy-to-use user interface that is identical for GPS and TPS, operators are instantly productive. In addition, operators can switch instantly between GPS and TPS, and use whichever is the most convenient and suitable-with no extra training required. Not only is the user interface and application software identical, exactly the same database is used for both TPS and GPS, enabling seamless data transfer between GPS and TPS, saving time and money.


Measurement Devices Ltd.'s (MDL) Quarryman systems, known for reflectorless laser measurement of rock faces and volumetric surveys, feature horizontal and vertical angle encoders and a pulsed laser rangefinder. An automatic scanning feature allows the operator to define a polygon to be surveyed together with the required density of points, and the instrument carries out the scan with no further operator intervention. The instrument has an onboard memory and feature coding facilities; alternatively, data can be collected externally. The extremely rugged design is enhanced with a simple menu structure for maximum efficiency. Quarryman features 700 m reflectorless range, 128 Kb RAM internal memory, 360º x 135º continuous scanning area, and optional external remote control.

MDL's Laser-Ace scanner combines reflectorless "point and shoot" measurement technology with high speed laser scanning. The result is an instrument that can be used for both conventional total station survey methods, including point and shoot, control observations and 3D laser imaging. Complete scenes and objects in view at ranges up to 700 m may be surveyed. The Laser-Ace features an internal removable 32 Mb compact flash card for data storage of 3 million points and a scan speed of up to 250 points per second.


Nikon's NPL-302 series pulse laser stations feature exclusive focused beam non-prism technology. This unique focusing system provides positive target detection by focusing the measurement on the target and minimizing return signals (or multi-path) from targets outside the focused area. Additionally, the diameter of the laser beam is etched into the eyepiece reticle, providing positive beam size and location to the user and eliminating erroneous target recognition.

The latest NPL-302 series, DTM-302 series and the DTM-502 series total stations from Nikon offer faster EDM measurement, longer range, graphic displays and improved keyboard design. The new keyboard layout enables quick access to common field functions, and both prism and reflectorless modes to be available at the same time.

All instruments feature Nikon's easy-to-use, reliable, onboard data collection and layout routines, and data storage for 10,000 points in up to 32 jobs.


Northwest's NTBM5B is designed and manufactured to meet the demand of all construction jobsites. It features easy-to-use keypads and quick-access menu display. Long lasting battery ensures uninterrupted operation. Onboard intelligence, such as offset measurement, missing line, remote elevation, stakeout, coordinate measurements and more, allow contractors to do more sophisticated work fast. To endure the everyday vigor of the construction site, NTDM5B is made with IP45 class water/dust protection. Northwest provides a whole line of instruments, e.g. automatic levels, theodolites, total stations, rotating lasers and accessories, to meet the ever-increasing quality and economic demand of the construction industry.


Pentax R-300 series employ two unique features, automatic environmental sensing and auto focusing, and several other advanced features: absolute angle encoders, narrow visible beam EDM, laser plummet, camcorder batteries and IPX6 waterproofing.

The environmental correction (PPM) is calculated from data supplied by electronic temperature and pressure sensors. The operator does not need to measure or input this data; the instrument takes care of it automatically and continuously.

Telescope focusing has been automated with push button auto focus capability. The operator can also use power focus or manual focus for special situations.

Absolute encoders are used for faster startup, better vertical angle accuracy and more consistent horizontal reference angle orientation. The narrow visible beam lets users see the exact measurement point and get accurate distances into tighter spots than ever before. A visible laser plummet increases setup speed, standard camcorder batteries are low cost and widely available, and the IPX6 waterproofing gives serious weather protection.


Sokkia is introducing three new total station series that incorporate the latest patented RED-tech EDM technology: the Series030R3, the Series130R3 and the Series30R3. RED-tech uses an analog-to-digital conversion method to simultaneously sample measurements from three different frequencies. Samples are processed through advanced software to determine the best method for calculating distances based upon the measurement conditions. This means that accuracy is not lost, with equal precision on all target types. New for 2004, RED-tech has been enhanced with the addition of improved optics and electronic components. Reflectorless range has been increased to 350 m, with equal performance even at extremely close distances of 0.3 m. These new total stations are eye safe too, and include an automatic function that attenuates the visible signal to an equivalent laser safety rating of Class 1 when prism or reflective sheet targets are selected. New models also include Sokkia's patented absolute encoders for improved reliability and rugged durability in the field.


Topcon continues to bring innovative technology to the industry with a complete product offering of surveying instruments, construction instruments and GPS systems. New GTS-820 and GPT-8000 series servo, autotracking and robotic systems offer fast 12º per second tracking speed with movement anticipation firmware for high-performance tracking. Add the RC-2ii remote controller for radio-free optical communications and one-touch track beam acquisition. All work with standard prisms and no external batteries with cables. GPT-8000 includes high performance reflectorless measurement capability. The new GPT-3000 series incorporates Topcon's dual-optical technology, automatically focusing the beam for optimum accuracy for reflectorless and prism operation. Users can accurately measure 250 m reflectorless in demanding situations such as building corners or through chain link fences; the integrated visible laser pointer allows users to target the exact point of measurement. The new GTS-230 series offer wireless Bluetooth communications.


Q. When choosing a Trimble total station, how do you decide which EDM is best? DR Standard, DR200+, DR300+ or IR High-Precision?

A. Simply compare each EDM option against your job requirements and select the one that's best for you.

  • DR Standard, Trimble's phase shift DR, is available on the Trimble 3300, 3600 and 5600 total stations. The high-precision short-range reflectorless work provided by DR Standard delivers the precision needed for architectural and engineering surveying.

  • Long-range pulsed-laser DR200+ and DR300+ are available on the Trimble 5600 Servo-Driven total stations. DR200+ and DR300+ are ideal for long-range and extra-long-range reflectorless everyday surveying.

  • For extremely high accuracy to a single prism, choose the specialized IR infrared option.
