I've got a Sovereign GT and the headphones I like are too loud (no volume control on them) without me turning the volume on the detector all the way down. Many Sovereign users say that the volume control on the detector should be at full and then the volume on the headphones adjusted to a comfortable level. The theory is that this will allow deep/soft signals to come through easier, though I haven't seen any specifics on why it would matter if the volume control is adjusted on the detector or at the headphones but in general that's what I've heard people say.
Anyway, rather than buy a simple volume control to plug in between the headphones and the detector I figured I might look into one of those audio boosters that will raise all audio yet keep anything real loud (like surface coins or a large target) from getting real loud, in other words limiting it's volume past a certain point. I just did a search on the net and can't find any devices for this meant specificly for a metal detector, or at least any small ones that would work well with being carried around while hunting. The only one I could find was on Kelly Co's site and it's called the Depth-Doubler and is made by Champion. There is almost no information on this product and I can't find it on the web for further info either. I did run across a DIY project that looks interesting and can be built for less than $20, but I have yet to read into it to see if it will also block very loud audio which would be needed on a detector.

Anyway, if anybody has any opinion on the Champion, knows of any other commercial ones that work well, or has any links to other DIY jobs please post a link. My main concerns are having it boost low audio but also blocking stuff from getting very loud, that it doesn't degrade the audio detail, and it would be nice to still be able to hear how deep the target is based on it's loudness. In other words, not making everything the same level of volume where you can no longer tell how deep the target it.
