The key thing when viewing coastal breaks is to view at the correct angle. Looking at a flat wing at 90 degrees seldom works. Hold the specimen at an angle, so that you are looking obliquely towards the base of the wing. It takes some practice, so find a specimen which you know should have costal breaks, and work on that first. Good luck! :)
