Summary: I bought this for hunting in the fall so it would match up with my son's GPS. It is great and anyone who has one can be located on the map as to where they are. This was also less than half the price. I am happy with it.
Summary: Needed for work to keep in touch with other crew members. Works great out in the field. Everybody knows nexactly where their located. The Garmin 520Cx GPS Receiver does everytrhing I expected of it.
Summary: I bought the Garmin Rino 520 a few weeks ago and was immediately impressed with the number of features available on this inexpensive hand held GPS. The GPS size is perfect for carrying in a pocket and the battery has a pretty good lifespan of roughly 10 hours.
Summary: I currently own a 530HCx,and love it, so I bought my wife one so we can communicate, and also pinpoint each other if one of us gets lost. We also have 10 other riders that have these as well. A super great product, and a great safety tool.
Summary: Like the display clarity, ease of use, 5watts of power, satellite pickup sensitivity (worked in heavy fog), ability to upload topomaps. Exceptional GPS and two way radio in mountain conditions.
Summary: Product is definitely very good, the only reason of my "good" is that there is more advanced option - newer Rino 520HCx. I own both and 520HCx preferable due to the _much_ higher sensitivity of the GPS receiver its quick start and approximately 3 times quicker map redrawing.
