Let me start out by saying that I am not sponsored by Hydrowave. Mine is an honest and objective opinion.

I've had one for almost a month now and I really like it. It has a lot of different settings and I'm still learning when and how to best use those different settings.

There have been a few times when I was 99% sure that it made a difference in catching more fish. I feel like the more I use it, the more I'll learn what settings work best, when it works best, etc.

If you think about the concept and the theory behind it, it makes perfect sense. We are able to mimic and call in just about any other animal that I can think of. From calling in ducks, coyotes, and crows, to rattling in deer, there's definitely something behind the theory here. Why shouldn't we be able to call in bass and other gamefish? They are predators just like a coyote, bobcats, etc.

I am very optimistic with the results I have seen from the limited time I've used mine. If a fisherman is expecting a MIRACLE, I think he might be disappointed, but if he is expecting the unit to make a DIFFERENCE, I think he will see that over time. In fishing (especially in my business and in tournament fishing), extra bites can make all the difference in the final outcomes of our days. For me, it is a worthwhile investment.
