Designed for hunters who demand precision and comfort, the Phelps Pinnacle Series 3 Pack features tall dome diaphragms tailored for high palates and serious elk callers. Each call in this set is built with a different latex thickness and stretch profile—letting you fine-tune pressure, volume, and tone for your personal calling style.

Whether you need soft cow mews or thunderous bugles, this 3-pack gives you the flexibility and fit to get the job done.

What's Inside:

Pinnacle 1 – Light Build
Light latex and stretch require minimal air pressure—ideal for soft cow calls, subtle tone variation, and finesse-style calling.

Pinnacle 2 – Medium Build
Balanced latex and tension make this a versatile, go-to diaphragm for both cow calls and bugles with moderate air pressure.

Pinnacle 3 – Heavy Build
Thicker latex and tighter stretch allow for aggressive bugles, high-volume cow calls, and long-distance calling. Best suited for strong air pressure.

Why We Like It:

• Tall dome design for high-palate comfort and better control

• Three distinct builds = more sound range and calling confidence

• Hand-built by Phelps for premium fit and consistent performance

• Great for intermediate to advanced callers
