Megallan’s eXplorist 510, 610 and 710 reflect the experience Magellan has in designing an accurate handheld GPS navigation device suitably rugged and waterproof for outdoor trips and hiking. The inclusion of an inbuilt camera and microphone so that each trip can be documented with geotagged images and voice narration all ready for later sharing makes this a product for the next generation of social network savvy hikers. An excellent product.
