GeoSpectrum specializes in underwater acoustic transducers. For nearly two decades, we have been meeting the needs of our customers as designers and manufacturers of hydrophones and sound projectors as well as consultants on the integration and testing of acoustic systems. Whether it is from our existing product line or a custom design, our experience can help you define your needs and find a transducer that best meets them.

GeoSpectrum produces hydrophones, sources, and acoustic sub-systems. We produce standard products that can be found on this site, but excel at producing specialty products to your requirements at short notice and at affordable prices. We also provide consulting services and have designed transducers for a number of customers for their own manufacture.
