Assuming you’re trout/red fishing out of the boat in either Galveston or Matagorda bay (Or any bay on Texas coast) what advantage is DownScan giving you in 7′ of water or less? It’s not to identify oyster as that’s easier to differentiate on traditional sonar. It’s not seeing baitfish because baitfish are easier to see on traditional sonar.
