Hi, I was hoping to get some feedback from anyone that has the Navonics Plus card. I just bought the card for my humming bird 859hd. I will be fishing mostly Lake Huron, St Clair river and Mitchells Bay, Lake St Clair area. I was told at the store that it has great detail in these areas does anyone have this card to verify the information I was given, and if you like the card or not. Thankyou
Paul
