The Trimble M3 DR 5" is a lightweight, compact total station that incorporates Trimble Accessâ„¢ field software that enables users to quickly collect, record and calculate survey data. Utilising long range Trimble DR (Direct Reflex) technology with precise Nikon optics and a Class 2 pointer laser, the EDM (Electronic Distance Measurement) device provides highly-accurate measurements that can easily be imported into CAD (Computer-Aided Design) software.
