Troy1976,

I currently have a lowrance HDS unit. I think the GPS is great but I have not been happy with the sonar. I would suggest going to two seprate units and reccomend Furuno for sonar. If you have time call Gil Travis @ 209-848-8533. Gil is an expert on sonar he can build a system for you. If you happen to have a problem with his product he will bend over backwords to help you.
