Can you adjust lake level with this set up? I had some invalid depths when close to shore on the deep shield lake I was on.
I’m sure the the Helix’s were accurate because of the baits we were trolling but the charts were WAY OFF!
I thought water level offset was only an option if you used compatible LakeMaster chips.
Check your manual to confirm but I think this is one of those features that only resides inside the Johnson Outdoors family(bird, Mkota, Lakemaster)
Follow the contour is another feature that is likely Johnson product specific.
Like Pat said, you need a LakeMaster chip to do water level offset and depth highlighting.
Get a Zero Line Card and turn on Auto Chart Live and start mapping.
To use follow contour you need a high def map from LakeMaster or you can use the map you make yourself with Auto Chart Live.
Thanks all!! That’s disappointing, the lake I fish isn’t in lake master
