Navionics or Lakemaster

[sushi1980]

Hey guys, just got a new/used rig and I want to get a chip. Im running the following:
Helix 12 SI on the console
Hummingbird 999 SI on the bow
Terranova w/ auto pilot I link.
Both the Lakemaster and Navionics cover the same lakes in my area so Im not sure which one will give me more features. Looking for feed back.
Thanks

YOu can view the current maps on the Navionics website's Chart Viewer.

You can download the Lakemaster lake lists from the Humminbird Lakemaster site.
There are three levels of maps:
Standard Definition
High Definition Survey
Lakemaster High Definition Survey--very good since those were done by Lakemaster survey teams.
