my hook 7 the depth keeps flashing at 60 feet did hard reboot still does same sting gps works fine anybody every see this problem hooked my head unit to my buddys hook 7 transducer still does same thing

Do you have the depth setting set to automatic?

Just the other day I was sitting in 20 feet of water and the graph was only going to 8 feet.  Somehow I accidentally changed the setting from auto to 8 feet.  

I had a hook unit last summer that did that every time I went out with it. It doesnt like to find bottom. Usually the reboot would fix it for awhile, but it would always do it again eventually. I just ended up replacing it with an elite ti unit. Hooked up to the same power source, mounted in the same spot, transducer in the same spot, and the elite series hasn't messed up once. Hook units are junk in my opinion. There are several threads on here about hook units not finding bottom.

Mine finds the bottom great but the GPS is so slow to update that I'm looking to buy a different unit and use the Hook on the bow.
