The only difference I noticed was the platinum had a 3d feature which allowed you to look at the land like you were looking at google maps but other than that the premium did just as well and had the same info.WilAdditionally, on every unit Ive used my Navionics Platinum Chip all my unit runs noticeably slower. That includes my HDS8 Gen2, HDS7 Gen1, HB997, HB1197 and HB898. Like the two posts stated get Navionics Premium. The 3D contour view is overrated IMO. Looks cool but slow. I just turn it off on my HDS8 use it like Navionics Premium. Now when future processors speed up maybe then but right now its ahead of its time via hardware. Again, my opinion.
