I bought a Navionics card recently because the website said that it had 2 of my local lakes listed on it. When I went to the 1st lake and switched the chart mode on my Lowrance HDS from the Lowrance map to the Navionics chip, the Navionics map was a ridiculous picture of the lake. So I surmised that this lake was really not on the card.
Well I went to another lake this past weekend that was supposed to be on the card and I got the same result. I will post a pic of the Lowrance chart and then the Naviionics chart.
Attachment 161454Attachment 161455As you can see, the Navionics map on the right is unhelpful. The Lowrance on the left is great. Is there some other setting on the HDS unit that I must use to get a better picture from the Navionics map? thanks.
