Just bought a used boat that has this unit on it.
It seems to work fine but I am unable to get it give the "arch" symbol for fish. I am also having trouble getting it dialed in just right to be able to show stumps or other structure sticking up from the bottom. Right now it just gives that goofy "fish" symbol for everything.
I have downloaded the owners manual and have read through that.
Any thoughts or suggestions would be mucho appreciated.
Thanks
