中文版：
Garmin eTrex 201X是一款專為戶外場景設計的多功能手持定位設備，兼顧農業測量、野外勘探與戶外運動需求。該設備搭載雙衛星定位系統（GPS+GLONASS），通過多頻段信號接收技術，可在復雜地形中實現快速定位，定位精度可達3米以內，滿足土地面積測算、路線軌跡記錄等專業需求。
機身采用高強度工程塑料與防滑紋理設計，符合人體工學握持體驗，同時具備IPX7級防水性能，可在暴雨天氣或意外跌落水中的情況下保持正常運作。2.2英寸抗反射液晶屏支持四級灰度顯示，在強光環境下仍能清晰呈現地圖信息與數據參數。內置1.7GB存儲空間，可預裝全國基礎地形圖，并支持自定義航點標注功能，單次記錄航點數量可達1000組以上。
針對農業用戶開發的智能測畝功能，支持不規則地塊的快速面積計算。用戶只需沿地塊邊界行走，設備即可自動生成閉合軌跡并顯示精確面積數據，測量結果可保存為獨立文件便于后續分析。航跡返航功能可引導用戶沿原路線安全返回起點，特別適合森林巡護、野外考察等場景。
持續工作模式下，兩節AA電池可維持18小時續航，配合省電模式可延長至30小時以上。擴展功能方面支持USB數據導出，兼容主流GIS軟件格式，便于后期數據處理。無論是農田規劃、登山探險還是地質調查，eTrex 201X都能提供穩定可靠的位置服務支持。
English Version:
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.
