The Role of Precision in marine
A common mistake people make is relying purely on cell service or basic maps. Real navigation requires understanding raw coordinates. When you are engaged in marine, a 10-meter error might mean missing a hidden trail, a geocache, or a vital waypoint.
Pro Tip: Formats Matter
Different apps use different formats. Google Maps prefers Decimal Degrees (e.g., 40.7128, -74.0060), while specialized handheld GPS devices often default to DMS (Degrees, Minutes, Seconds) or UTM.
