Topcon introduced the GPT-7000 reflectorless total station series, featuring an on-board controller with Windows CE operating system. A touch screen display and a user-oriented graphical interface allow fast, precise data collection and survey functions without a separate controller. The EDM's unique dual-optical, pulse laser design provides focused beam accuracy on long distance measurements. Measurements can be made reflectorless up to 250 m, and up to 3,000 m with a prism. In addition to the unit's internal memory, the external compact flash card slot can expand available data storage and transfer data between the instrument and an office computer. Four models are available featuring 1, 2, 3 or 5 arc second accuracy.
