I have an HDS 7 Gen 2 Touch and love it but have to agree that a bigger screen would be nicer but it cost more. The different models get confusing but if you want the HDS 7 and fish shallow water & u want structurescan - then you want to get the bundle part #000-10778-001. It comes with two transducers...the 83/200 transducer and the LSS2 transducer (u need a separate transducer for structurescan). I bought mine online from
www.thegpsstore.com $1,199 with a $300 mail in rebate, free shipping, no sales tax.
