Thanks Everybody,
I'm purchasing the Lowrance HDS-7 Gen 2 Touch with no Transducer (I'm going to use my current HDI Trans, which is compatible with the HDS). I have spent allot of time researching this and it gave me the most options. It seem to me that the HDI sys has run its coarse and Lowrance seems to see the HDS Gen series the future. I like that the fact i can pick and choose which upgrades i like and purchase them later down the road, as my techn and abilities get better. Now i know there are pros & cons to each side of the conversation, but i'm a man that likes allot of options when getting a new piece of equipment, and the HDS-7 Gen 2 gives me those and future ones down the road. I would like to personally thank Wayne on his inputs, which are straight forward.
