Thanks for the very informative reply. I've found the deepest water in the ponds I fish to be about 15 feet. Without the sonar I would have assumed many spots to be 20 feet deep or even more. I'm often marking trout (Solid icons) cruising 3 feet down over deeper water. Does that mean they are right under the tube? If so I could almost kick them with my fins. I believe I read somewhere that the sonar detects fish from the air in their air bladder. Is that correct?
If the fish symbols do not appear again when maintaining a relatively stationary position I'm assuming that indicates the fish were on the move. If you were anchored and the symbols were still there after the screen scrolled by and refreshed itself that should indicate the fish are holding in that position and depth. Would that be correct?
What type of sensitivity setting is best for water under 15 feet deep?
