In This Article
Buying a handheld GPS for land surveying is frustrating because the market mixes consumer hiking units with professional RTK systems that cost ten times more but look similar on paper. Accuracy claims are often vague, battery life is quoted under ideal conditions, and it's hard to know which features actually matter in the field versus in marketing. Many buyers end up overspending on RTK gear they don't fully use, or worse, underspending and discovering their coordinates drift by meters. The comparison below breaks through that confusion by focusing on real-world surveying performance, value, and long-term reliability.
