lets talk sonar,was watching fishing shows saterday i wathed a man sitting in 30 feet of water in his boat watching his graft while a fish swam up and took his biat and swam off,then he set the hook ,caught the fish .Is our tech. that so far advanced?
If so,how do you fine tune the sonar to do so?
Ive noticed there not alot of discussion on sonar and how they are fine tuned.
would like to see more in put on this topic.
