I see you have a 64 ft cone on your A scope . I know the cone gets wider at the bottom . And the fish were at 20 ft deep . How do you know how far to cast out ?
Just had to reset my sonar setting on my garmin 4 anyone got a good video on getting them dialled in? Had it dialed for icefishing but now on open water having alot of issues
The sonar creates a cone below the boat. In theory, the deeper the water the wider the diameter of the cone at the bottom. General rule of thumb would be to drag behind the boat but either side, especially in a kayak, gets you close. The fish will most definitely see your bait , depending on water clarity of course.
