66--Dual-Frequency Identification Sonar (DIDSON)

The Bureau of Reclamation believes that the University of Washington, Applied Physics Laboratory, 3935 University Way N.E., Seattle, WA 98105-6613 is the only firm that has the capability to produce this product. The Bureau of Reclamation (Reclamation) has a requirement for a Dual-Frequency Identification Sonar System that includes operating system software and one days training at the vendor's site. The sonar system is needed to observe and quantify fish movements and responses in turbid water at various Reclamation sites where water quality is poor. The system shall include a submersible transducer and acoustic lens, cables and junction box Specifications: Dimensions: 30.7 cm long by 20.6 cm high by 17.1 cm wide Weight in air: 7.0 kgs Weight in water: 0.6 kgs negative Low Frequency Mode;.
