Hydrophones can be a useful too for quickly identifying if areas of a pool may be leaking without getting in the water, but they can be difficult to position in order to hear the proper noises. Some of this frustration can be avoided by attaching the hydrophone to the end of a pool pool. You can then position the microphone exactly where you want to listen instead of tossing and dragging it along the pool floor.
A pool pole also isn’t your only option. One of our customers even attached his hydrophone to a telescoping fishing pole for a more permanent solution that was easy to store and didn’t have to be removed when otherwise using the pool pole. Creativity typically pays off when it comes to leak detecting!
