Title: Cheap and Simple Hydrophone Preamplifier/Amplifier for Headphones.
Post by: Davy1 on August 20, 2011, 08:49:25 am
One of my "summer projects"  has been to have  look at making hydrophones more easily and cheaply available.

They are very useful things for our hobby. They can pick up motor, pump and even servo noises at ranges of 10s of feet underwater. The more hydrophones there are at the pond side, the better for all of us hence this article. I hope this link is useful to my fellow model submariners
