Searching for a Leafy Seadragon is like a game of hide and seek.
More often than not the dragon will have been in plain sight all the time, just visually blended into its environment. Rather that covering lots ground in the 'seeking', instead just move a few metres and then just wait and watch for a minute or two. If nothing interesting appears then move on a few metres and wait and watch again.
Patience and a willingness to allow the dragon to just appear is the best strategy in this game of hide and seek.
