Introducing the Riven Eclipse Carbon Fiber Bugle Tube. The ultimate carbon fiber bugle tube designed for elk callers who refuse to compromise. Engineered from cutting-edge carbon fiber and polycarbonate, the Eclipse brings together unparalleled strength, durability, lightness & tonal precision caller’s demand.
At Riven, we understand that elk hunting isn’t just a hobby—it’s a passion, a tradition, and a grind. Simply put, we built the Eclipse for those who push the limits and seek the best.

Why Carbon Fiber?
Carbon fiber is well known for its strength, durability, consistency & sound quality. In recent years, carbon fiber has become widelyrespected within the custom guitar making industry. Carbon fiber is known to produce a balanced, rich, and resonant sound. It also produces a more sustained and articulate sound than other traditional materials.

The Nature of Sound:
We all know that, “Tone” can be a very subjective topic of conversation in the calling world. We also understand different tonalities will match different calling styles. In our minds, there is a common understanding of the elements that make up a pleasing tone such as volume, frequency response, overtones, definition of notes and sustain. The Eclipse was carefully designed to beautifully encompass all the above.

The Eclipse is not just another bugle tube. It was carefully crafted to help you deliver crisp, commanding sounds of a bull, the perfect blend of volume and “sound carry” to cut through the thickest timber or deepest canyons.
