I have the East Great lake chips in the Gold and absolutely love them, They show great detail and all contours, and major rock piles, weed lines, marina's, launch ramps etc. It is a good price as at the show they were 239.99 but that is for the lateset version. I was lucky and went down to Cabela's PA and bought the 901gold chip for a great deal. The hotmaps does not show the water contours and depths detail as the Gold chip but it does relate to land and all lakes in Ontario without the detail for navigation. If you are looking for the best marine chip go with the Gold.
