Garmin water offset help

[Champ2]

Hello

I have three Garmin 122's and a 126 ultra

I have a Gamin Lake view chip in one unit and a blank SD 32 gig card in one

all 4 are linked together, I can't get the water level offset to work ?

I can add or increase the level but it won't allow you to lower the level when you try to lower the level you lose all contour lines ?

Any help would be greatly appreciated

Dynamic lake level adjustment requires the Garmin LakeVu g3 Ultra mapping card to work.
Also need to go to the website below and type in the lakes you are fishing to see if this
function is even available (not all lakes have it). I see you’re in California also, so if you get
this worked out be aware that the adjustment goes to 99.9’ and you well know our lakes
drop much further than that. Hopefully this answers what you were asking .

You cannot set the offset in your garage, you have to be on or near the water for the the function to work. Sounds odd, I know, but called Garmin and this is what they told me. Went to the lake and sure enough, the feature worked.

i was going to buy the Ultra just for the dynamic lake level, then I read the fine print of the 99ft. Doesn’t help us much in Nor Cal. When Oroville, Shasta and Melones drop over 150ft all the way to 190ft for several months. Does the Ultra work with the tides and adjust depths for the Delta? That would be nice to have and save a prop

After several attempts to resolve the issue with the help of the Garmin rep , it appears I have a bad Lake UV card
