Boobies are primarily utilized in two effective methods when fly fishing for trout. The first method, known as the washing line technique, is vital for keeping your flies suspended in the feeding zone of the water. This is a highly successful approach for fishing large stillwaters. The second method involves using a Booby as a lure on a fast sinking line, allowing you to target fish that are deeper, just above the weeds at the bottom. Mastering both techniques can significantly increase your catch rates and overall fishing success.
