The Final Fantasy XI radar allows you to have a map that shows all the current monsters on the map, players and some times items. Using a radar helps you the most out of any program available simply because it will increase your efficiency at finding the mob you are looking for. The radar is most of the time used in all MMORPGS. However most players when they want a radar or think of a radar they want a special radar program or hack. With that radar program or hack it will allow players to see far more than they should be normally. It will allow for example a player to see specific items on the map and special areas that they find of interest. Also it will show other players on the map for distances that an average player can see. The biggest advantage is seeing special mobs on the radar to help you in hunting specific mobs for certain types of loot.
