Hear Fish Talk & Whales Sing How to Make Low Cost Hydrophone-Also Find Your Pool Leak
How to make a low cost super simple hydrophone and listen in to the underwater world.
Many people have bought these kits from me to help them find their pool leaks too.
If you need a longer cord on your hydrophone Radio Shack still sells a 10 foot extension but if you go that deep you will need to use a permanent sealant like silicone to keep out the water.
If you would like to buy a kit to make one of these please go to
