Depth finder off set tige touch

[Pudder]

Hey everyone, I purchased a 2013 z1 and have noticed the the depth finder reads about 10' shallower than the water actually is. I don't see an obvious menu to ad an offset to the depth, is it even possible or to I just have to live with the reading it gives? Thanks!

I don't have the touch screen on my boat but on my boys 2012 rz2 I saw that function when I was playing around with it. I'll post back with specifics next time I go out on it if you haven't figured it out.
