Frequently Asked Questions

Should I Travel with my HydroWave Mounted on my Boat?

In short, we recommend that you always disconnect and safely stow your HydroWave when trailering and traveling with your boat.

The HydroWave unit is designed to be waterproof during normal boating conditions, including rain, however, driving on the road adds excessive amounts of stress to the unit, and it can force moisture in and increase the chances of breaking the seal.

Are the sounds real?

es, all the sounds are recorded with a highly tuned hydrophone in a natural environment.

What are the sounds?

All of the sounds produced by the Hydrowave are naturally occurring sounds of the following: Shad clicks (natural sounds that shad make as they school in a passive mood. Gill flairs (natural sounds that predatory fish make when sucking in prey. These sounds are similar to humans taking in a big breath but much more violent and aquatic in nature). Swim bladder pops (natural sounds made during the crushing of a prey fish’s swim bladder). Crushing sounds (Predatory fish have crushers at the opening of their throat that are used to crush and disable prey. Sounds made by these crushers are violent and very audible in an aquatic environment). Regurgitation (Often a predatory fish will gorge on bait when schooling. Once their prey is disabled they will regurgitate it and suck it back in as they swallow the previously eaten prey). Fleeing noises (As bait flees its attacking predator it will make distinct sounds and vibrations that reflect prey in a panicked mode).

What fish will it affect or work on?

The sounds emitted by the Hydrowave have proven to elicit a response on almost all predatory fish. While all fresh water fish have not been tested by Hydrowave, customer feedback and testimonies have been positive on all species. In a nutshell, the Hydrowave is “not” Bass specific.

How does it work?

Simply put, predatory fish hunt and detect prey based on three main senses (Sight, Smell and Sound). Sight and Smell are the most limited senses so predators rely on sound and the vibrations of low frequency sound to detect both the presence of prey along with the location and its direction of travel. The Hydrowave emits these sounds triggering a feeding response. Hence the phrase “Ignite a Feeding Frenzy”.

What sounds should you use and when?

This question is very complex and will require some experimentation on behalf of the user. We have provided a laminated field use card for reference. The short answer is “Mimic your environment”. Fish will respond more positively to a natural sound indicative of the current environment. The more aggressive an environment the more aggressive sounds should be used. The more passive and environment the more passive sounds should be used. Be a predator and pay close attention to the environment and mood of the fish and mimic it with your Hydrowave.

Do you use it always?

This is personal preference however, using all senses of a predator when fishing only makes sense. We recommend that it always be used even if in a very limited fashion.

Is the Hydrowave designed for deep or shallow water?

Results from using the Hydrowave are equal in both deep and shallow water. Impulses can be triggered both vertically and laterally.

Will the Hydrowave interfere with any transducer?

No. This has been tested to have shown that they are on completely different wavelengths.

What percentage of Pros are using the unit now?

90-95%
