The 480 is a great unit and should show you what you need to see, but the Lowrance HDS units look really great. My concern with the HD-5 is that the screen would be too small to split. I think I will go with the 7 or 8. The split-screen features of the HDS are very cool looking.

The good thing about the HDS is that it will be upgradeable to StructureScan side-scan later this year (or whenever you can afford it).

There's a 10% coupon for WestMarine.com and some videos on the HDS units on www.topfishfinders.com . There are also some videos on how to set up your Lowrance/Eagle fish finder.

Good luck with your new toy.
