Silicon Nitride II

Silicon Nitride II is an improved version of the original ring, making it a perfect ceramic guide for heavy duty rods. It was designed for use as ball bearings in jet engines, because of its tremendous hardness factor and high wear resistance. If it can handle the heat and friction of a jet engine, just imagine how well it will perform under the toughest fishing conditions. And if there ever was a ring built for wire line, this is it. Silicon Nitride has the strength and durability needed to tackle any kind of saltwater fishing.
