The Garmin eTrex 201X is a versatile handheld GPS navigator engineered for outdoor applications, integrating agricultural measurement, field exploration and adventure sports capabilities. Equipped with dual-satellite positioning (GPS+GLONASS) and multi-channel signal reception technology, this device achieves rapid positioning in challenging terrains with accuracy within 3 meters, making it ideal for land area calculation and route tracking.
Featuring a rugged housing with ergonomic grip design, the device offers IPX7 waterproof protection to withstand heavy rainfall or accidental submersion. The 2.2-inch anti-glare monochrome display ensures clear visibility of map data and navigation parameters under direct sunlight. With 1.7GB internal memory, it supports preloaded base maps and allows custom waypoint marking for up to 1,000 individual points.
The specialized area calculation function caters to agricultural users by enabling fast measurement of irregular land plots. By walking along field boundaries, the device automatically generates closed-loop tracks and displays precise acreage data, with results saved as independent files for analysis. The trackback feature guides users to retrace their path safely, particularly valuable for forestry patrols and scientific expeditions.
Powered by two AA batteries, the device delivers up to 18 hours of continuous operation, extendable to 30+ hours in power-saving mode. Data export via USB port supports mainstream GIS software formats for post-processing. Whether for farmland planning, mountain trekking or geological surveys, the eTrex 201X provides reliable positioning solutions with professional-grade performance.
