Depth offset

I have a 93 sv chirp. How can tiu manually adjust the depth offset. I've looked everywhere I can think of. Out on Kentucky lake and need help.

I am not sure but I think it is the chart section menu

If you are referring to the Dynamic Lake Level feature (to adjust your Chart depth contours based on the current lake level), you must have the LakeVu HD Ultra accessory mapping card for that feature.

Thought he might be after offset for ducer depth. Home page to SETTINgS to My Vessel to Keel Offset. Negative number to allow for ducer on the TM. Don't have the manual here to see the page number if this is what you want

Thank you.

Todd,
Are you sure? I thought that I changed mine without the ultra. But I remember it took a long time to find it. My lake is down 8+ feet.
