Jiggin One, Went to BPS today to look at Elite 7 HDI. I think you are mistaken about the two transducers. This unit has 2D( 83/200) and (455/80) DI, all in the same transducer and is capable of transmitting 2D and DI at the same time This is the first Lowrance other than one e/w Structure Scan that can do so. This cost 699 at BPS. Someone speak up if this is not correct....Thanks, guys!!!
