CB-150 Data Buoy

The CB-150 data buoy is designed for smaller water bodies, portable or short-term deployments, and applications requiring compact or low-power sensors.



Compact data buoy


With an overall 24-inch diameter by 63-inch height, the CB-150 can be deployed quickly and easily from a small boat. Fully configured systems typically weigh less than 100 lbs.

Solar powered data buoy


Three integrated 8-watt solar panels are angled and evenly spaced around the buoy to capture sunlight from any direction and provide adequate battery charging.

Data logger and telemetry well

Data Well

A 10-inch diameter by 12-inch tall data well provides a watertight housing for batteries, data loggers, sensors, and other hardware.

Data buoy sensor ports


The data well lid provides pass-through connections for sensors, power, venting, and more. When integrated with the optional NexSens X2-CB data logger, the system is truly plug-and-play.

Deploy underwater sensors

Top-to-Bottom Ports

Three 2-inch pass-through ports allow for sensors to be mounted underwater while securely routing the cable. Instrument deployment pipes and custom sensor mounts attach to 2-inch NPT bottom threads.

Data buoy navigation beacon

Solar Beacon

The optional solar marine light has a one to three nautical mile range and securely mounts to the buoy top plate for maximum visibility.

Data logging buoy

Data Logging

The X2-CB data logger replaces the standard pass-through data well lid for turnkey systems. Alternatively, 3rd party data loggers can be integrated by the user inside the data well.

Cellular, radio and satellite telemetry

Wireless Communications

Communication options using the X2-CB data logger include Wi-Fi, radio-to-shore, cellular, and Iridium satellite.

Compact durable data buoy

Built to Last

Constructed of cross-linked polyethylene foam with a heavy polymer skin and an indestructible stainless steel frame, the CB-150 is designed for years of service.

Case Studies

A New Kind of Sentinel on Lake Superior

For more than 100 years, the Stannard Rock Lighthouse has kept a watchful guard over Lake Superior. But now, a new weather buoy is joining the watch in a remote part of Lake Superior, providing much-needed weather data to local mariners, the National Weather Service (NWS), and researchers. Scientists from the Superior Watershed Partnership (SWP), Lentic Environmental Services (LES), and the University of Colorado-Boulder deployed the buoy on the lake […]

Bermuda North Channel Dredging

Similar to how shipping vessels are getting larger and larger these days, cruise ships have too. Newly designed cruise vessels are longer, wider and packed with more amenities to give guests the best trips possible. But there are costs to larger ships moving in and out of the world’s ports. In Bermuda, an island nation whose economy runs on tourism, its ports have felt the impacts of the shift. Government […]

Kadettangen Beach Construction Project

Not far from Oslo, Norway, a massive effort is underway to expand a public beachfront. The work is taking place along an area of Oslofjord called Kadettangen, a small peninsula that juts out into the bay. Once the work is finished, public officials expect that the new beach area, along with other enhancements planned for the peninsula like bike paths and volleyball courts, will help attract visitors from near and […]
