A common question that you hear is “is there a site that one can go to for a profile to fit a GPS to the person and needs?” Generally you can go to any of the major manufacturers' web sites and find comparison charts on their models. Most manufacturers have comparison functionality on their web sites that could help determine what to look for. It looks pretty basic, and you may have already determined what you are looking for. Now you just need to find the right unit. First you must decide what type of unit are you looking for – automotive GPS systems, motorcycle GPS, marine GPS chartplotter or fishfinder, handheld GPS units? I especially like Garmin's site for doing comparisons of GPS device features. There you can pick your interests (basic handhelds, mapping handhelds or on the side there is a link to geocaching). You can learn a lot from their site, and they have a wonderful comparison feature. This would be a terrific place to start. If you like geocaching there are also sites such as geocaching.com which teach you a lot and are a lot of fun. I generally like helping you find answers to your questions, but at the same time a feature which makes great sense to one person will sound like a waste of time and money to someone else, so you really need to do the final homework yourself to be sure you really find the GPS unit which suits your needs and that you will love for some time to come. I hope this helps to simplify things a little for you.
