Hi have a fcv800 how do I set this up to fish on the bottom at 300+ mtrs?
also sounder is not reading properly over 50 mtrs ?

If it is isn't reading over 50 meters, it seems that must be fixed before worrying about how to change the range to work at 300 meters. What transducer do you have installed? Do you have photos of it working at different depths you can post?
