[TG] [TG11] Element 9 HV digital depth loss

[olygreen]

Thank you for the reply. I think this is my first ever sonar that will not let me choose a custom depth range on screen while keeping the true depth. So my question is will the targets on the screen, when I am only showing the top 100ft of water in 600ft of water, be accurate or anything else to worry about? Also on the attached pictures how do i get rid of the blue mass in center of screen that follows bottom?
