Distinguishing Large vs Small Fish on Sonar
Furuno makes a FF with a length measurement ability that helps distinguish small fish from large fish. Here is a large lake trout (46") on the bottom with several smaller trout/kokanee supended near the thermocline. Sitex also has a measurement capability on their 750.
