The Joom Deep Diver fly measures 5" and will fish well in a wide variety of situations. This is a great Pike fly but will also work well as a Largemouth fly as well. When stripped, the Joom Deep will push water and dive just under the surface; creating a lot of commotion on the water. This will get the attention of any predatory fish near by and often result in hard hits. This will also work well in "Jungle" fisheries for Peacocks and other aggressive species.
