I hunted for three hours in a fresh water lake. After all the talk about how these headphones aren't loud enough, I had the volume limit at 30. It didn't take me long to realize it was WAY too loud. I realize that I wasn't hunting in the surf with a lot of ambient noise, but I have no need for them to be louder in the fresh water environment. As for the detector, I really like it as a water machine. I have owned and hunted with the Excaliburs a lot. The CTX is superior in every way. And the Excal was my favorite water detector. Since I will not be diving deeper than 10 ft, I see no reason to own the Excal any more. I love the audio. I was in combined and really liked it. There is so much more information sent to your ears with the CTX over the Excal. Also, do not worry about depth. It's at least as deep as the Excal 1000. In fact, I think it's deeper, but I want to get more hunts in with it before I say for sure.
