Garmin EhoMap UHD2 settings help

[MikeMcD]

Hey guys, I just installed a new ECOMAP UHD2 9”  with GT56UHD on my boat. It is working good but I know it can be better. It’s just running pretty much at factory settings now. I get some arks but can’t see my riggers. I generally am fishing between 80 and 300fow. I was hoping you guys can give me pointers on what settings work best for salmon fishing. Anything will help, I know nothing. Thanks in advance I appreciate the help.

What do u have ur hertz set at? The lower the hertz the better I run 83 on mine it's not a Garmin though.

Also if u can't still see them u can tilt ur transducer slightly  to  pick up ur cannonball if it bothers you to be in 100 ft and ur graph shows 106 u can go into advance mode look for transducer off set then u can make up the diff their.
