The HydroWave™ is a patented electronic sound device that emits the natural sounds of bait fish and predatory fish feeding on them. Together the sounds produce an instinctive response in nearby predatory fish such as large mouth bass that can hear the sounds and feel the vibrations of the sound waves in the water. By doing so, the fish are drawn in the direction of the device eager to strike any bait it finds. When used on a boat, this device is intended to give fishermen a considerable advantage in catching a greater number of "keeper" fish.

The HydroWave is primarily sold as a boxed set, the HydroWave System Package. The HydroWave System Package gives you everything you need to use the product to generate the sounds and sound waves from your boat. The HydroWave Sysem Package includes the Control Unit, Underwater Speaker, and all the mounting supplies necessary.

HydroWave™ Science

Tactile Sound Transmission (TST) is the primary output of the HydroWave’s speaker system. Finely tuned amplifiers deliver the tactile sound. Tactile sound is different from ordinary sounds because it is sounds that you can actually feel. The concept is easy. If you have in earplugs you will not be able to hear people talking around you but you will feel the sound of a sub-woofer. Fish hear on that type of tactile level and frequency. The same frequency and sound produced by the HydroWave.

Lateral Reactive Technology

LRT is a vibration wave technology that operates at a frequency level that stimulates a predatory response through a fish’s lateral line. As with any predator, fish are stimulated to the presence of prey. A fish is stimulated primarily through its lateral line. The lateral line is naturally tuned to detect low frequency (1 – 80 Cycles) vibrations created by small prey such as shad, herring, minnows and others. The Lateral Reactive Technology of the HydroWave produces these vibrations in patterns that create a predatory response.

Vibration Reactive Technology

VRT is a vibration wave that operates at a frequency that stimulates a predatory response from fish through their inner ear. Contrary to popular belief, most fish do have ears. The fish ear is not like the human ear. Instead of funneling sound like a human, a fish ear consists of dense bones under the skin that detect and translate vibration. This vibration detection is so accurate that a bass is completely able to differentiate between vibrations of prey and other sources. This explains the reason behind how blind and visually impaired fish are able to continue to feed. The bottom line is that natural vibrations will elicit feeding responses from predatory fish where unnatural vibrations will not.

Vibration Patterns Used

The vibration patterns are that of natural sources of prey. Minnow’s, shad, herring and schooling bass fry are the primary vibration patterns. Other vibration patterns resemble water displacement associated with feeding or schooling fish. This pattern is most important in stimulating the competitive nature of the fish along with the instinctual schooling signals.

"HydroWave Ignites a Feeding Frenzy"

Sound travels further and faster in water than it does in the air, about 4.4 times as fast which is the equivalent of 5000 feet per second. This speed combined with the poor visibility characteristics of water is the reason that a fish is so dependent on vibration and water displacement through TST’s for the location of prey. Most bodies of water are cluttered with sounds from outboard engines, swimming and recreational activity to construction of boathouses. The source of sound clutter is always present. This forms the basis of how fish have developed keen senses that allows them to specifically identify clutter from prey and feeding activities of other fish.

With sound representing the key component for identification of a sound source in fish, it is important for us to understand some basic elements of sound transmission.

Many things can affect the speed of sound, including not only the nature of the medium, (gas, liquid or solid) but also its temperature and any other additive substances, such as water salinity. Basically sound travels faster through denser and hotter materials.

As in a human, fish produce sound and vibration in two main ways, intentionally and unintentionally. Unintentional sounds are constantly being produced, mostly by swimming and feeding. However they make a far greater variety of sound intentionally. Fish communicate with other fish for a variety of reasons such as schooling activity, mating activities, scaring intruders away, alerting of prey, alerting other fish of predators and so on. These sounds are universally similar and not very complex. Scientists describe them as grunts, scrapes, knocks, clicks, squeaks, groans, booms, thumps, rumbles and drumming. Nearly all the species studied so far produce their sounds using their teeth, swim bladder or a combination of both. Species that produce sounds using their swim bladder usually have special muscles attached to it for exactly this purpose.

Fish try to take advantage of the sounds other species make. Thus some Bass will use sound to help them locate their prey while some smaller fish can detect the sounds larger predators make in their hunting. These sounds can be detected from great distances.

Can Fish Hear ? YES!

Fish hear and sense movement in the water with both their "ears" and with the area that connects their body to their tail called the Lateral Line.

The Lateral Line is a sensory organ consisting of fluid filled sacs with hair like sensory apparatus that are open to the water through a series of pors (creating a line along the side of the fish). The lateral line primarily senses water currents and pressure, and movement in the water.
