BUDGET HYDROPHONE KIT! HEAR FISH TALK & WHALES SING!
Jacque Cousteau's The Silent World is not really silent.
Hundreds of the nearly 20,000 species of fish make some sort of sound; there are popping pistol shrimp, chattering friendly dolphins and the spine tingling and hauntingly beautiful songs of the magnificent whales.
Sound travels nearly five times faster underwater than in the air. It travels 1500 meters per second under water as opposed to 331.6 meters per second in the air, and the sea bottom, sea surface and the separate layers of different temperature water help to transmit sounds underwater for miles and miles. The undersea world is not really silent at all!
I have always wanted to be able to listen underwater without having to dive but have never had an affordable hydrophone to use until now.
Recently, I bought a box lot of new, low cost and simple electronic listening devices at an auction to resell. These were advertised as microphones that help to eavesdrop on the conversations of others. I tested one and listened to a distant conversation to see if they worked and was disappointed. I could hear the people talking but not much better than with my own ears.
However, I was surprised at other sounds it picked up. I could hear the sound of my socks on the tile floor as I walked across my living room and the low hum of the elevator in use outside my door- both sounds were inaudible without the listening device. It clearly amplified sound of a certain frequency.
I realized that although the device would be a failure at eavesdropping ( not really a bad thing) it would be great at picking up certain frequency sounds. This led me to wonder how good it would work if I could try it under water.
I spent a day or two coming up with a way to waterproof one of the microphones and making it into a hydrophone. After I waterproofed it, the very first time I used it from my boat to listen underwater I was hooked. The cord is only 4 feet so you need to use it from a small boat or the boat dock or seawall but there is no reason you could not splice on a longer cord. This is not a professional model hydrophone costing hundreds of dollars. This is just a low cost, but surprisingly effective listening device you can make yourself - a low cost, low budget, anyone can afford one, hydrophone!
Using this simple listening device I have been able to hear Dolphins right here in Biscayne Bay!! I have also heard a variety of other sea life, especially at dusk.
I have assembled a simple kit that will allow you to make a low budget underwater listening device that is very easy and quick to make. If you can open up and heat a can of soup you can put this kit together. The kit has everything you need but a battery and is only a twenty minute project- there is no wiring or soldering or special tools needed. I have a limited supply so you need to order soon if you are interested.
Complete and thoroughly illustrated assembly directions are in a CD on a folder written in HTML so anyone's computer can open it up and read it.

U.S. Navy Diving Manual, Rev.4, 1999. CD-ROM; 942 pages and divided into 5 volumes.
This manual is huge and encyclopedic in scope. It covers nearly all-conceivable aspects of diving from the earliest diving history to the latest new procedures on Nitrogen-Oxygen (NITROX) Operations and even Diving at High Altitude. This is a great addition to any divers personal library and would also make a unique and welcome gift for a fellow diver.The paper version is over $30 per volume so this is a $150 value.
This official U.S. Navy Diving Manual is an update of previous revisions and provides the latest procedures currently being used by US military divers.

I have also added the complete US Navy Salvage Engineer Manual on CD, another added value$$$
EXTRA FUN Item # 4
I would like to add to the Hydrophone Kit a very unique and personal copyrighted guidebook I wrote a few years ago called, " Your Online Goldmine Guidebook". If you win this auction, you not only get the items mentioned above for one low price but you also get the electronic or ebook version of the guidebook I wrote based on my personal experience on starting my own part time and eventually full time business with Internet auctions. It is a very popular and fun to read 129 page guidebook that has sold over 2000 copies on eBay alone. Some of the Internet resources listed in the book are now outdated as the Internet changes so quickly but the personal narrative and business part of the book is still relevant and well worth reading. I think you will enjoy it.
Below are just a few comments from past buyers of the guidebook.
Praise: Great item--better than described! Fast shipping. My compliments! Recommended!
