Using the Gaia app on an I-Pad, accuracy without GLO is 2+-213ft. With GLO 2 it improves to +-16 feet. Elevation accuracy has also been improved to match the elevation shown on the topographic map. Easy to use and small in size (slightly larger than a Zippo lighter). It's a very affordable way to get a phone or tablet to behave like an accurate GPS device without sacrificing on old technology in a few years.
