Cetacean Research Technology (CRT) is a U.S.-based manufacturer of underwater acoustics and bioacoustics instruments located in Golden, Colorado, operated by CetResTec, LLC. Its core business includes hydrophones, portable and autonomous underwater recording systems, acoustic tags, signal acquisition interfaces, and analysis software packages, serving use cases such as scientific research, engineering noise monitoring, commercial whale watching, education, and artistic recording. The website emphasizes that since 1994, it has supplied universities, government agencies, businesses, and individual users in more than 65 countries worldwide.
CRT’s products are built around “capture—record—analyze”: hydrophones such as the CR1A, CR3, C57, C75, C56, and C305 cover multipurpose, wideband, low-noise, directional, or omnidirectional monitoring needs; systems such as the CR1-200-SP, C75-200-SP, and C56-DR680-SP bundle hydrophones with TASCAM recorders or the SpectraDAQ-200 USB interface and SpectraPLUS software; RUDAR, nRUDAR, and µRUDAR provide short-term or long-term autonomous underwater recording; and Acousonde is designed for cetacean tagging applications. The company also offers suction cups, protective cages, professional audio accessories, and custom systems.
The website clearly states that prices are not displayed and that customers need to contact the company for the latest quotations; in certain regions such as Europe and the Middle East, purchases can be made through distributors. Payment options are extensive, including major credit cards, PayPal, bank wire transfer, Bitcoin, and UnionPay. Nonprofit organizations and some students may be eligible for discounts. International customers are responsible for any import duties and taxes.
The advantages are its focused specialization and complete product lineup, making it suitable for needs ranging from entry-level whale-watching monitoring to serious scientific research and engineering monitoring. The company can also provide product selection advice, customization, and training based on specific applications, reducing the risk of mismatching professional equipment. The drawbacks are that the purchasing process is traditional, with no online ordering and non-transparent pricing; the website design is somewhat dated and information is scattered; and the standard warranty for hydrophones is only 90 days, so long-term projects may require additional warranty coverage or backup units.
It is suitable for marine bioacoustics researchers, environmental and engineering noise monitoring teams, university laboratories, government agencies, whale-watching companies, documentary filmmakers, and nature sound recordists. It is not suitable for users who simply want to compare prices quickly and place an online order for a consumer-grade underwater microphone.
Judging from the nature of the website, it appears to be a standard U.S. corporate site with no obvious reliance on special application services, so it is likely accessible directly from mainland China. However, actual purchasing involves cross-border shipping, customs duties, English-language communication, and return-to-factory repairs for after-sales service, so buyers should allow for a longer procurement cycle.
