The Origin & Technology of Hydrowave

Advancements in electronic technology continue to amaze professional and novice anglers. You can include the HydroWave in that select group of electronic devices. It’s unique and innovative sound technology has blended aquatic biology with electronic engineering to produce the HydroWave.

Before tournament angler, creator and founder of HydroWave, Gene Eisenmann, developed the HydroWave there wasn’t an electronic device that created sound to stimulate fish in production. The concept of producing sounds to arouse fish only existed in lures and one sound producing device that's no longer being produced.

Eisenmann with years of angling experience knew sounds transmitting from lures often trigger strikes. Lipless crankbaits are excellent examples of lures that produce sound that attracts and incites fish to strike it. Rattling lures are popular because they excited fish to bite and anglers caught fish on them.

Motivation behind the HydroWave began after a fishing tournament on Lake Norman. Eisenmann was catching fish on a drop shot early in the morning, but once it got mid-morning the bass would stop biting. He could still see the bass on his sonar unit, but they wouldn’t bite. His frustration level grew when several of the bass would follow a lure, but refuse to bite it. On his trip back home, Eisenmann kept thinking over and over that there should be a way to naturally stimulate fish to get them to strike lures. In the end, Eisenmann developed the concept for sound technology.

The HydroWave ( is a complex electronic device built with input from scientists, engineers and professional anglers. It uses both Lateral Reactive Technology and Vibration Reactive Technology to stimulate a feeding response.  Lateral Reactive Technology utilizes wave technology that a fish feels through its lateral line while Vibration Reactive Technology uses a vibration wave through the fish’s inner ear.

Development and commercial production of the HydroWave was enhanced when Eisenmann introduced the concept to Robert Palmer. Palmer had previous experience with electronic product and development; in addition to being the owner of RHP Industries in Aubrey, Texas. “I showed Robert what I wanted and he did the engineering and tooling to produce the HydroWave,” said Eisenmann.

Two other people would also join Eisenmann in the business enterprise. They were Bassmaster Elite Series anglers Jeff Kriet and Kevin VanDam.

“Fish make sounds underwater like bass when flaring their gills to suck in prey or crushing them when eating,” noted Eisenmann. Eisenmann compared the crushing noise made by a bass to that of humans eating potato chips. “It’s surprisingly loud,” revealed Eisemann.

“Baitfish also make sounds. Shad make an audible clicking noise,” Eisenmann went on, “plus when a shad jumps out of the water it makes a unique audible sound. A bass can tell the difference between a shad jumping and a rock being thrown in to the lake.” 

Similar to a sonar unit, the HydroWave is a tool anglers can utilize to catch more fish. “An angler should think like a predator fish when using the HydroWave. The key is to consider the environment like cold water or warm water temperatures and what sounds will pull them in and keep them close,” pointed out Eisenmann.

On Lake Fork in Texas, Eisenmann has used the HydroWave to catch bass. “I was fishing around a bridge for a nomadic school of bass. To get them actively feeding, I would set the HydroWave on frenzy shad. The bass would start schooling then slowly stop. I would then put the HydroWave on passive shad setting which would ball the bait up, once they balled up I would turn it on frenzy shad and the bass would start actively feeding. We did this process over and over again all day long catching bass,” explained Eisenmann.

Another scenario Eisenmann addressed when fishing utilizing the HydroWave was flipping and pitching. “I like to set my unit on frenzy shad and volume at medium. This is an aggressive setting, but not so loud that it stimulates bass farther away than where you are pitching to.” noted Eisenmann.

HydroWave unit comes with a field use card. The card explains each of the sound settings that’s available in the freshwater version. For saltwater anglers there’s a saltwater version of the HydroWave with its own unique sound loops. 

Currently there are three different units available.

Saltwater HydroWave Package:
*Shrimp Sound loops
*Mullet Sound Loops
*Croakies Sound Loops

Freshwater HydroWave Package:<
*Shad Sound Loops include Frenzy Shad, Schooling Shad, Fleeing Shad and Passive Shad Finesse.
*Shiner Sound Loops include Frenzy Shiner and Shiner Panic

KVD Signature Series HydroWave Package with the 6 KVD Exclusive Sound Loops:
*Power Pattern
*Feeding Frenzy
*Delayed Schools
*Finesse Fishing
*Ultra Finesse
*Schooling Blitz

Sound technology has been taken to the next level with HydroWave. It’s Lateral Reactive Technology and Vibration Reactive Technology produces a series of sounds that stimulates fish. For anglers, it’s one more tool that’s available to use when out fishing.
