THE DEVELOPPER
Hi there !
Welcome to Divenetics, my name is Malik and I am a mechanical engineer graduated from EPFL Switzerland in 2018.
Passionate about mechanical engineering and thermal systems I started diving thanks to my Fiancee and my father. Today I am a rescue level diver.
I am specialized into chip cooling, microfluidic and thermodynamic. As I am always looking to simplify or improve things I knew I had to do something about the noise and water swing in the ears induced by our exhaust from the secondary stage. This was the initial push induced by my father's feedback.
Few years ago I started thinking about the Husher in order to try to remove as much as possible the pain and noise you start feeling after few dives or consecutive dives.
Also I had to carefully develop a plug and play system while keeping a strong focus on the exhale pressure drop !
Finally, during the whole 2025 year I converged to a design making the Husher an upgrade that makes a difference and that is not a fake money trap.
I tested the prototypes in the Leman lake in Switzerland, french polynesia and Egypt. I lend the prototypes in the hands of dive intructors in order to be sure the noise and pain improvement would be something validated by dive experts.
I hope you will find the upgrade a nice one as I do :)
Enjoy the visit
Cheers

Mission
Husher was developed through iterative acoustic and fluid-dynamic testing focused on improving underwater exhaust behavior while preserving natural breathing performance.
The system combines flow management, acoustic diffusion, and multiphase fluid interaction to reduce harsh exhaust signatures without modifying the regulator’s core breathing mechanism.

Iterative Prototyping
The Husher system was developed through multiple design generations involving iterative testing, geometric refinement, and underwater validation.
Successive prototype generations explored:
- outlet distribution patterns,
- internal flow geometries,
- liquid-balancing pathways,
- and acoustic diffusion strategies.
Each iteration was evaluated through comparative testing in order to optimize the balance between:
- acoustic behavior,
- breathing resistance,
- flow stability,
- and integration compatibility with existing regulators.

Engineering Philosophy
Husher was not designed to eliminate underwater sound, but rather to improve how exhaust flow interacts with the surrounding water environment.
The engineering approach focuses on:
- reducing harsh tonal peaks,
- smoothing acoustic behavior,
- improving exhaust-flow distribution,
- and preserving natural breathing performance.
The result is a more refined underwater exhaust experience developed through practical testing, fluid-dynamic iteration, and acoustic experimentation.
SCIENCE & ENGINEERING
Patented Technology
The Husher system incorporates proprietary acoustic-flow management concepts currently subject to patent-pending protection.
The technology combines:
- distributed exhaust geometries,
- multiphase liquid-balancing pathways,
- internal flow conditioning,
- and acoustic diffusion mechanisms,
to influence underwater exhaust behavior while preserving regulator functionality and diver comfort.
