Preston's Triple Threat Pack includes a full range of callers for every situation, including the three most popular diamond cut callers. The Sapphire is a close- to mid-range "finesse call." The White Diamond is a good, solid mid-range call. The Black Diamond is the building block of all diamond calls known as "the call that started it all." This is the most versatile call on the market. If you can't cal him in with these calls, you'd better change to a friction call. Because, odds are, he can't be called with a diaphragm.
