GPT series

    Topcon is the world leader in survey instrumentation.In fact,Topcon changed the way topograpy and layout work is done.We continue to lead the industry with time-saving solutions-from the 1976 introduction of the guppy,the First Total Station,to quick-lock,onboard imaging,and long range EDM(Electronic Distance Meter) technology.

     

    GPT Series features:

    • Expanded import and export for CAD packages
    • Exclusive enhanced right mouse support
    • Expand on-board memory or move files using Compact Flash Technology
    • Use the mini USB port to connect to activesync
    • Rechargeble batteries provides increased operating times
    • Most powerful reflectorless EDM available(2000m)
    • Pinpoint accuracy with narrow,focused beam

    The GPT_7500 provides the world's longest range refletorless EDM:6500+ft.(2000m).Its reflectorless beam measures what you want to measure,even when shooting through obstacles such as fencing or tree branches.Reflectorless equals safety;stop sending a rod man into dangerous terrain or high traffic situations.Take shots of areas that are difficult or impossible to access from a safe distance.
