Hi Huey the Gamin 750s is on sale at a majour boating camping outlet for $1299 including transducer but I'm still confused as to what I want think ill just stick with my old sounder for now fitting a new Bimini so sounder might be on hold. I don't like buying from those majour outlets as they don't seem to care about there customers so I will certainly contact you when I'm sure of what I want so I don't waste your time thanks.
