One thing, there's this knob on the right hand side of the hydrophone, you can click on the top half to only turn up the hydrophone volume, without having your speakers louder, this helps when people in the apartment below get woken up by the panicked cry of Alaaarm!!
(my neighbours hate me,:rotfl: )
Also, good hunting with the hydrophone, it's my favorite method, just lurking and listening for unsuspecting merchies...
