Re: Lowrance LMS480 Which maps to buy?
Many dealers will have a demo chip available for you to look at before purchase. <br /><br />The quality of the freshwater maps varies widely. The chip manufacturers look around for any available maps and then chooses what they believe to be the best. Sometimes they are good and current maps. Some could be based on survey maps produced 10, 20 or more years ago. <br /><br />If your dealer doesn't have a chip to look at, you may be able to contact Navionics directly and ask them to send you some sample screen shots of the map you are interested in.
