Map card help Lowrance HDS Gen II
Navionics is for Lowrance. If you have a unit with base maps only, you can buy the Lowrance Insight card. The HDS units can show Navionics and Insight side by side at the same time. Navionics shows the contours better and Insight shows the creeks and other original structure of the lake better. Insight also covers where the Navionics doesn't. Navionics doesn't show up the rivers as well because the lakes that I use were at low winter pool when they were surveyed, and they couldn't get all that info then.
I run the Navionics and the Insight at the same time for the best of both worlds. You find the creeks and old home site etc with Insight and you can tell what kind of contours they were in with the Navionics. Most of the new HDS units have Insight built in.
