I have the Rhino 530, works good, lots of info, Talk feature works nice, only for all the features to work, others in your group need to have one also, all the rhinos will work together. Otherwise Garmin 60 works real good, way more memory for maps etc. the etrex models work good also, it's nice to have trail maps of riding areas, with routes to truck etc. Any Gps receiver will work well, learn how to use it, some are easier than others to operate, ask those out riding what they use, and make your decision from there
