I am looking to upgrade the HDS 5 I have currently. I was looking at the HDS 8 Gen 2 with the structure scan. First, is the structure scan necessary?(only fish the islands for walleye) Second, what do you gentlemen think of the Lowrance in general. I have been happy with the old unit...just looking for advice. I know this belongs in a different forum, no one seems to look down there until spring...
Thank you,
Glenn
