The ERT-5 Reflectorless Total Station is an affordable 5" accuracy instrument designed for construction applications.

The measurement programs provide angle/distance, missing line, remote elevation and area measurement functionality.

The instrument has no onboard memory or no data input/output capability. A laser plummet provides convenient setup over survey marks.
