@Honeebuket Ok, Mepps has been shooting their lures in a Flow tank(That is what I call it) for a little while now. It is in water, and the basic principle works the same as a air tunnel used to test aircraft designs. I would like to see the syclops and Littlewolf spoons captured on video like this. It helps to know what you are presenting to a fish. Now, If you look closely in the vid, you can see little air bubbles going by in the water.
@Honeebuket Why dont you try using a mepps before you criticize it because if you knew that... then you know that mepps look exactly like that underwater.
