Looking for help selecting your hydrophone system?

See the Selection Guide along the top bar of the website. From there, you can select a system from the table and go directly to information about that hydrophone system, or you can select a category of systems and explore from there.

Where are the prices?

Please contact us by email to get an access code for seeing the latest pricing.

Do you take credit cards?

On orders under $1,000 we accept credit card and ACH/Wire transfer or check.

On orders over $1,000 we accept ACH/Wire transfer or check only.

How do I place an order?

Place your order by contacting Cetacean Research Technology. Online ordering is available once we review your order since each system is often customized for each user's application.

How long will it take to receive my order?

The short answer is approximately one to eight weeks. The long answer is that many Hydrophones are in stock and can be shipped within one or two days, but some models are built to order and ship within six weeks of the receipt of order and payment. We ask that you allow at least two extra weeks for custom orders. The actual shipping time depends on the shipment method you select.

Do you give discounts?

Yes - to qualifying nonprofits - student discounts are also available on some items.

What is the warranty period?

All hydrophones carry a 90-day limited warranty. Extended warranties are available. Units will either be repaired or replaced at the discretion of Cetacean Research Technology. Misuse or damage to the connectors or cable voids the warranty.

Do you create custom systems?

Yes - if our standard hydrophone systems don't perfectly fit your application, please let us design and build the best system for you.

Where can I find information on the M-Audio MicroTrack II compact recorder? It looks like it has been discontinued.

Yes you are correct, it has been discontinued so that page is a little harder to find. You can find the specifications and frequency response characteristics here (M-Audio). Discontinued Accessories has a full list.

Do you retain the manuals for discontinued products?

Yes we often keep copies of the information that we had online while the products were for sale. Take a look at discontinued hydrophones & systems on our old website for links to photos, plots, and manuals for discontinued products like the Cetacean Research™ C54 hydrophone series. You'll find links to discontinued recorders such as the Edirol R-4 or M-Audio MicroTrack II and other accessories with discontinued proaudio accessories.
