I bought my Navionics card for the exact reason mentioned above... the available lakes. A few years ago I was looking for a map that was better than the base map on my 997. Half of the places I would be running would show up as dry ground on the base map that came with the unit. Navionics had many lakes in Florida but it only had 4 lakes in Alabama. I contacted them to ask why and they basically said nobody had asked for them. They said if I could provide them with information about the lakes and show documentation showing that tournaments were held on the body of water, they would add the lake to the list of updates for the next year. I provided them the information they requested and the next year the two main lakes that I fish were added to the card. They listened so I bought their product. I have been very pleased with both my Hotmaps card and my Platinum+ saltwater card I use on my Gulf boat. The Navionics card is a good product that I am happy with.
