Congrats on the new unit. It doesn't get any better. Am runnin HDS 10 and HDS 8 with E-Net--fantastic. Spend time gettin to know the HDS 10, it's one powerful tool. I keep my rig parked in the garage. After install I sat on bar stool beside boat and learned to navigate the HDS screens and menu options for a week. Saved a lot of time on water readin a book.
