what is Vibro-core internal damping?
The backstory
RamRods Archery began with a vision: how do we make the bow sound and feel better?
In the earlier days of archery, one of the only solutions for vibration damping was to put a rubber damper on the stabilizer. It did what it was intended to do, but with a few drawbacks such as increased wind drag and failure to target vibration from inside the stabilizer itself. Our goal was to create internal damping technology to provide clean, responsive feedback without any decrease in performance.
In 2017 we developed our original Ultra stabilizer, which was our first hollow rod. We tested everything from sand to various liquids to even nontraditional materials like wheat flour, until we found a particulate that consistently produced the best results. This initial success wasn’t enough. After that, we experimented with different formulas, ratios, shapes, and particle sizes. Some particles were too fine for optimal vibration damping, so they were scrapped. It was a struggle to find the perfect ingredient, and trust us, we looked everywhere-- at one point shovels were involved!
where we are today
In 2018, we finally found it. It had everything we were looking for: the right weight, the right characteristics, and the right feel. From that, we created the perfect blend of fine rubber powders, carefully selected for particle size, shape, and flow characteristics. It includes moisture-resistant additives to keep the material freely moving inside the stabilizer. No clumping, no degradation. This finely-tuned recipe helps absorb and redistribute vibration throughout the shot, delivering a smoother, cleaner reaction during follow through. The Matterhorn stabilizer was the first one to include VIBRO-Core and every rod we’ve made since then has included this proprietary technology as a standard feature.
Once you try a stabilizer with VIBRO-Core inside, you’ll never go back!
VIBRO-Core lives inside the rod so it never adds any wind drag. It adds a negligible amount of weight to the stabilizer to preserve your set up balance and shot timing. Most importantly, it improves feedback clarity, and reduces post-shot noise and resonance.
We even started using VIBRO-Core in some of our accessories, like our EDGE Carbon extensions! This way you can maximize internal damping throughout your stabilizer system.
