TOPCON GTL-1200 Robotic Total Station and Scanner in one

Construction Verification Every Day GTL-1200

Quick layout and scanning with a single instrument
Wi-Fi enables point clouds to be transmitted wirelessly
Proven robotic total station design, integrated with a scanner
Full dome scan in seconds, now with 2x point cloud resolution
Scan density tailored to minimize software processing time
Point clouds accurately matched to BIM model coordinates

With this new instrument, one person can cut the time of a conventional topo in half and we no longer have to do the extra day of time and labor for that floor flatness and floor levelness report. That translates to a savings of around 60% in labor costs per pour.
