FWIW : I saving up to buy a sidescan.
I've been out on a few boats with them and they are amazing.
Most charts are old info - even though updated to the newer machines. The shallow waters under 35 feet often have not even been surveyed in last 30 years. The deep channels / edges are - ship pilots need to know where to go / not go.
I keep a close eye on my finder while fishing / running and have found some great unmarked spots. Little humps / bumps / wrecks that are seldom fished can really save the day. The well marked stuff gets hit hard.
Sidescan - IMHO - should find even more of these out of the way spots.
One of my favorites is nothing more then two old concrete pipes - 18 inches dia by about 12 feet long. Nothing on any chart - found them by accident scuba diving. Sidescan showed them clearly.
