Caviar spinners have a build in offset tungsten ball in the fish egg imitating body - giving unparalleled casting distance and a true "Non-kink" function. The grade A stainless steel blade has been perfected in shape, after thousands of hours of test - to give perfect rotation in both rivers and streams as well as still water - even at slow speed and immediately as the spinner hits the water. Each spinner is tank tested and is an individual piece of Jewellery, constructed by high quality components and equipped with customised Japanese treble hooks. Superb for Trout, Salmon and most Predators. Size 4 hook.
