Hello Bioacoustics list,
Uh, this might sound a little weird but my brother & I have this
science project where we're trying to influence fish using an
underwater sound projector (home made). We're having problems
controlling the orientation of the gizmo in the water. Are there any
web sites with photos/sketches showing how the pros design their
hydrophones etc to maintain a fixed orientation underwater.
Our device uses a piezo transucer bonded to an aluminium plate so it's
not omni-directional. There are some images at

Thanx for any tips.
