Kevin and Jason break down the design choices that make their calls easy to run—and easy to maintain—plus what’s next from the shop.

• Field-first design: threaded speck call guts and user-friendly assemblies you can take apart, clean, and reassemble to the same tune.
• Materials that matter: early  ...
