CaviDyneLLC employs a revolutionary technology known as Ultra-Cavitation for underwater cleaning using much lower pressures than conventional equipment. These systems are significantly more effective, efficient, and ergonomic than the traditional ones such as pressure-washers/water-blasters, or grit blasters, and they eliminate the dangers associated with the use of high-pressure cleaning equipment. CaviBlaster systems remove marine growth in significantly less time and with better results than traditional methods - while costing less to operate. The compact CaviBlaster units clean steel, concrete, wood, rubber, fiberglass or fabric, without damaging existing surfaces or surface coatings. The more powerful CaviBlaster models will quickly clean surfaces to bare metal, stripping away heavy fouling and oxidation. Our biggest CaviBlaster is known as the ConcreteBlaster, and is powerful enough to crush concrete. Our Technology is powerful enough to clean any density surface; while not inflicting damage on painted ones. Additionally, our studies have shown that the force exerted on a diver's arm by the instrument when cleaning is comparable to that of holding a cup of coffee.
