I have owned Silvertron Products Co. since 1987. I purchased Silvertron from a gentleman that started the company in the early 1970’s. Since the beginning, Silvertron spinners have always been made in Sacramento California. I can proudly say they are the number one salmon trolling spinner in California. Silvertron spinners are unique and stand out from all the other spinners because of their high quality silver plating. In the water, silver shows up bright, where chrome and nickel shows up dark in the water. The salmon can see a Silvertron a lot better than plain nickel or chrome blades.
