 GPT-3000LW Series Features: - 1200 Meter Reflectorless range – New long range reflectorless mode leaves competitors far behind. Measure 300m to ANY surface!
- Bluetooth® Communications – Tethered to your instrument with bothersome, trouble prone, expensive cables? Not any more! Just add a Topcon FC-100 or FC-2000 with wireless Bluetooth capability and forget your cable problems forever!
- Precise measurements – The ability of the 3000LW to measure long range is significant, but real advantage of this technology is what this increased measurement power means at shorter distances. The Topcon GPT-3000LW outperforms all other reflectorless total stations when measuring to difficult targets such as hanging wires or dark asphalt.
- Dual Laser optics – Our dual laser optics system uses one narrow beam for non-prism functions, and a broader beam when using a prism for more stable long-range measurement.
- Visible laser pointer – Our state-of-the-art visible diode technology puts a bright, flashing spot of light exactly at the point to be measured. And our Class 1 laser is so safe, you can use it in heavy traffic areas.
- Putting the competition “on-the-spot” - Most reflectorless instruments use a laser for distance measurement, with varying spot quality over distance. Topcon’s GPT-3000LW uses the industries most advanced, highly focused infrared beam for a very stable, sharp spot that is less resistant to “spreading” over distance.
Topcon’s GPT-3000LW uses a dual laser optics system, one narrow beam for non-prism functions, and a broader beam when using a prism. This stabilizes the beam over long distances providing accurate measurement, even in adverse atmospheric conditions such as heat shimmer. Specifications | Telescope | | Length | 150 Millimeters |
