Float Collar
Easier to deploy than a tripod, just insert the icListen Smart Hydrophone into the Float Collar and lower it over the side of a dock or boat. A small 10kg anchor is enough to hold it in place in the correct orientation. If it’s bumped, it will move away and slowly return to its resting position. Our float collar is designed to be quiet, preventing the collection of undesired ocean sound. Depth rated for 1500m and 3500m.

icListen HF
Ocean Sonics’s flagship and finest products are the icListen high-frequency (HF) real-time smart digital hydrophones. Available in two sensor options as well as a variety of depths, the icListen HF can easily stream and record high-resolution acoustic data for many applications in the field.
Frequency: 10 Hz to 200 kHz
Applications: Ocean Observation, Pile Driving, Marine Mammal Monitoring, Vessel Noise
icListen RB9 (HF)
Ocean Sonics's most popular high-frequency icListen. With a 900 m depth rating and a Teledyne RESON sensor, the RB9 can easily stream and record high-resolution acoustic data for many applications in the field.
icListen AF
Ocean Sonics’s specialized audio-frequency icListen real-time smart digital hydrophone was designed and created to offer high-resolution acoustic data for specialized applications in the field.
Frequency: 1 Hz to 12 kHz
Applications: Tsunami detection, environmental monitoring, defense and security
“Ocean Networks Canada performed a wide range of tests on the hydrophones prior to deployment to verify the manufacturer’s specifications. The hydrophone instruments met all the manufacturer’s specifications and were easy to use. Both models satisfy our requirements for dynamic range, sensitivity and, most importantly, reliability. When coupled with the fast and friendly customer support we have received, these LF and HF hydrophones are a good choice for our ocean observatory.”
Tom Dakin Sensor and Technology Business Development Officer and Resident Ocean Acoustician Ocean Networks Canada
“We have been working with Ocean Sonics in our technology demonstration program since the first prototypes. Our science users have been very impressed with the very high quality data sets. Ocean Networks Canada is expanding our hydrophone network with Ocean Sonic icListen HF smart hydrophones across our observatory including new sites across coastal BC, as part of the Smart Oceans™ program. The compact size, Ethernet interface, high reliability and exceptional performance make these systems ideal for ocean observing applications such as mammal classification, vessel and ambient noise studies.”
Scott McLean Director(Former) Ocean Networks Canada
“I have used many different hydrophones on different systems, but these icListen hydrophones are the best I’ve seen in many years. They’re calibrated to very low frequencies where I’ve never been able to get reliable data.”
Ross Chapman Professor Emeritus University of Victoria
The Ocean Observatories Initiative (OOI) Regional Scaled Nodes (RSN) had requirements for very broadband hydrophones with good noise floor characteristics and a wide dynamic range. The icListen HF hydrophones satisfied these requirements at a reasonable cost. The hydrophones were quite easy to use out of the box, and easily passed our intensive First Article tests centered on assuring any instrument will not interfere with or corrode any other instrument. Customer support has been quite good, with very detailed questions answered quickly and accurately.
