Trimble M3 DR

This used Trimble M3 DR total station is a mechanical total station built for surveyors who want dependable performance at a lower entry cost than a full robotic system. The DR designation refers to its direct reflex measurement capability, allowing distance readings to be taken without a prism target in many field situations. It has previously served on construction sites and boundary survey jobs where flexibility between prism and reflectorless measurement was needed. The M3 line from Trimble is respected for its straightforward operation and rugged build, and this DR variant extends that reliability with additional measurement flexibility for crews working in varied terrain. Surveyors use it for standard tasks including topographic mapping, property boundary work, and general construction layout. It integrates with common Trimble and third party data collection software, making it a familiar tool for many field technicians. Sold here as a pre owned instrument, this M3 DR shows expected signs of regular field use but continues to function properly for standard survey operations. It is supplied with the typical accessories found with resale total stations such as a carrying case and basic tools. This unit represents a solid value option for a survey firm wanting reflectorless capability without the price tag of a robotic system.
