A PCMCIA port is also standard for external memory cards. To offer complete flexibility to your surveying procedures the GPT-8000A can measure in non-prism mode over a distance of 120 meters. This gives the added benefit to the surveyors working on their own, of being able to work behind the instrument to pick up those inaccessible of difficult to reach points. The GPT-8000A series are non-prism total stations with built in auto tracking offering the option for one person surveying from behind the instrument or at the prism. The GPT-8000 series features a large graphical display and a full alpha/numeric keyboard. Its high-performance motors rotate the 8000 at an astounding 50 degrees per second and fast servomotors will track the prism at a speed of almost 20 MPH (5 degrees per second) for faster target acquisition.

It also features a new Jog/Shuttle mechanism replaces the clamp/tangent screw for high-speed rotation and accurate target sighting. Data transfer to a personal computer or any data collectors is possible with the RS-232C interface. Unit is featured with IP-54 Waterproof/Dustproof rating, which is suitable for use in the toughest environments. Topcon’s exclusive optical data link eliminates the hassles and headaches of radio-controlled robotics. No interfering frequencies, no FCC licensing issues. With the addition of the RC-2II "Fast-Trak" Remote Location System, the GPT-8003A becomes a complete robotic one-man surveying system.
