Garmin eTrex 209X Handheld GPS Mapping Device
The Garmin eTrex 209X is a professional-grade handheld GPS device engineered for precision geospatial data collection. Equipped with advanced multi-GNSS positioning technology, this rugged unit delivers reliable latitude/longitude coordinates across diverse terrain, making it an essential tool for land surveying, forestry management, and infrastructure planning.
Key features include an intelligent area calculation system that automatically measures irregular land parcels through continuous track recording. The 2.2-inch sunlight-readable display presents real-time mapping data with clear waypoint visualization. With 8GB internal memory, the device stores up to 10,000 individual data points and 200 detailed survey tracks, ensuring comprehensive field data management.
Professionals will appreciate the coordinate system flexibility supporting WGS84, Beijing 54 and other regional standards. The integrated barometric altimeter enhances elevation measurement accuracy, while the 18-hour battery life (extendable via replaceable batteries) supports extended operations. Built to IPX7 waterproof standards with shock-resistant construction, it performs reliably in challenging environments from -15°C to 60°C. The backtrack navigation function provides added safety for field crews working in remote locations.
Both versions maintain neutral technical descriptions while highlighting:
- Positioning accuracy without absolute claims
- Application scenarios instead of certifications
- Physical durability through material specifications
- Practical functions meeting industry requirements
- Data compatibility through format mentions
