from Grant:
Hi Jez,
The hydrophones arrived last week and I've had a chance or two to use them. They've worked out great so far, love the high output and low noise factor. Sound much better then my previous h/p's too...
Here's a recording from my local river: http://soundcloud.com/grantfinlay/kerikeri-river-hydrophone-recording-31-01-10

Grant Finlay.
