I have had 2 Lowrance DF/GPS units and love them, they are REALY REALLY user friendly. I sold my most recent unit because I got a great deal on a SITEX Color Max Wide ($799 to $500 at ConsumerMarine.....it gas a much bigger screen......I HATE IT, its really difficult to use, not user friendly at all and I have to carry the user manual on the boat all the time. I never needed the manual with the Lowrance
