Lets see if there is any interest over here....
Anyone interested in this subject enough to start a thread? Ive had some PM's suggesting this and have talked it over with some other members who think it could be a fun and interesting topic.
I am just finishing up a similar thread on another board, so I have a lot of drawings and notes ready to go. It would lean a bit to the technical side going into the why behind what your screen is showing you and what its NOT showing you and how its not telling you the whole truth and all the truth all the time. There might be some math involved (not too much) and it might make some of you angry with your sonar..... hint - they have been lying to you from day one....
I have some screen shots to post and dissect and I would hope others would post some of theirs as well.
As usual, all questions, comments, suggestions, criticisms, arguments (as long as I win) and off topic asides, would be welcome. This is the internet after all
