I think the saying holds true, whatever your buying. you get what you pay for. I have the Lowrance hds-7 with structure scan. and I really like it. the hds-8 or hds-10 I think would be better. but they are a little pricey. if you go with the hds-7, download the 4.0 updates and it to will give you the 3 way screen split. just like the 8 and 10 does. ps. I think HB sells more units than all the other companies combined. but if I was buying another unit today, it to would be a Lowrance hds-7 or higher.
