When I go to https://fishfindersadvisor.com/hook2-5x-splitshot/ they show a a screen shot of the Hook2 5x Splitshot and the range on the right shows  Depth 0 - 40 in increments of 5 feet. My unit only shows The O and the 40 no increments are shown.  If you use this unit do you see the depth in increments on the right side of the screen or just the top and bottom depth?

 

I have the Hook2 7 inch and it shows the depth in increments on the side. 

I would look at the settings for you but it's boxed up due to my recent upgrade in that area.
