Okay I can't seem to find any good drawing or sketch programs for the phone so I will try to describe what I am talking about. Ill use the standard clock for vectors.
Okay so I am pursuing a fish who takes off towards 1:30. I don't think I can chase him so I take my spoon and stick my arm out to the right and flick it away or just drop it and I will swim in the direction of 10:30. The idea being that the fish will see the shiny object spinning and spiraling down and head to it or at least look at it and turn. While I am swimming parallel to the fish I have a second to get the shot off.
Many times the fish will turn and then immediately resume its original vector but at least one of three times they will full stop and sometimes change directions
