Rocky Mountain Champ 2.0 Diaphragm Call

The Rocky Mountain Champ 2.0 Diaphragm Call is a precision-engineered mouth call engineered for hunters who demand authentic livestock vocalizations across multiple pitch ranges. Designed for both novice and intermediate hunters, this diaphragm call produces convincing cow, calf, and bull sounds with the acoustic precision needed to close the distance on game responding to natural herd communications. Its compact, lightweight design—weighing just 0.02 lbs—makes it an essential addition to any predator or big game hunting kit where realistic bovine sounds provide critical cover and distraction strategies.

The diaphragm construction uses a dual-reed design that generates both standard cow and calf bleats alongside higher-pitched screaming bugle vocalizations, giving hunters multiple sound profiles from a single instrument. The call's geometry—measuring 6.25 inches in length with a thin 0.05-inch profile—optimizes breath control and tongue positioning for consistent tone production and quick transitions between pitch registers. This design reduces the learning curve for novice users while providing experienced callers enough sensitivity to execute advanced techniques like distress calls and heat-cycle vocalizations that trigger aggressive responses from territorial or protective animals.

Hunters pursuing elk, mule deer, or predators benefit most from the Rocky Mountain Champ 2.0's versatile sound palette, particularly during rut season when bull bugles and cow mating calls generate predictable approach patterns. The call's nasally cow vocalizations work effectively in open country where sound projection and authenticity prevent wary animals from detecting human presence. Compact enough to fit in a jacket pocket without bulk, this diaphragm call requires no batteries, moving parts, or maintenance—making it reliable in extreme weather and field conditions where mechanical calls may fail.
