I just bought the Version 1.0 Lakemaster Insight (lowrance) HD chips for Wisconsin. I could not find the 10 foot contours that were suppose to be on the lake. I called Lakemaster and they said that the data for Lake wissota was left off the chip.
I can send it in and get the data added or return it and get the 2-D chip with 1 foot contours.
I just thought I would let people know about this if they are considering purchasing the chip.
Again, this is only for the Lowrance Insight 3-D Wisconsin chip, Version 1.0
This spring they said they will be coming out with a new Insight chip with lake wissota in the 1 foot contours.
