Do any list members have experiences with commercially produced, inexpensive
( < $300 )hydrophones ?

I was wondering whether the recreational units (combination
hydrophone-amplifier)produced for kayakers and dolphin-watchers are capable
of detecting sounds made by aquarium fishes (like Cyprinella spp.).
