How many lakes on the Lakemaster card actually have in-depth contours showing for Ga? I just recently purchased the Minn Kota Terrova with iLink, a 598, 899 and the Lakemaster Southeast Card. These items were not cheap at all. I sold my Lowrance Gen2 units because of Hummingbird's Si and Di performance as well as being able to link my graphs with the Terrova. I'm wondering if I made a huge mistake now. Here recently after talking to several guys including the sales rep at BPS who had the same concern, the only thing they were told was that it was in the making and one sales rep said that was about two years ago. All the items that I have purchased are still in the box unopened. I know my one sale ain't a drop in the bucket to Johnson Outdoors if I decide to return them all but I'm sure there are other customers who are feeling the same way.
