Is my calculation of these 2 fish size correct?
I found these 2 fish huddled together at about 9 feet deep of water. I zoomed into water column between 7 feet and 9 feet. So, that's 2 feet of water. I know this sonar spots a 5 feet diameter circle cone in every 3 feet of water. Fish takes over about 60% of my screen. The fish size is about 2 feet = 60%*2*5/3 or 24 inches.
Do you agree?
