CB-25 Data Buoy
The CB-25 data buoy is a compact, affordable, and easy to deploy platform for both water and atmospheric observations.
With 18” (46 cm) hull diameter and less than 30 lb. (13.6kg) weight, the CB-25 can be deployed in drifting, tethering or mooring applications.
Three integrated 4-watt solar panels are evenly spaced around the buoy to capture sunlight from any direction and charge the internal buoy battery.
The CB-25 data buoy is designed for integration with the X2-SDLMC submersible data logger with integrated power supply, wet-mate marine connectors and optional wireless telemetry.
Two sensor ports with wet-mate connectors on the X2-SDLMC submersible data logger allow for integration with GPS receivers, meteorological stations, water quality sondes and other sensor types.
The X2-SDLMC submersible data logger is available with 4G cellular or Iridium satellite communications. The integrated antenna is nestled securely beneath the solar top.
Three 1.5-inch pass-through ports allow for sensors to be mounted underwater while securely routing the cable. Each port includes a slotted cap secured by hex bolts.
Three eye nuts on the bottom frame provide mooring points for tethering and mooring applications. The included stainless steel chain provides ballast weight, or an instrument cage can be connected.
Instrument mounting cages are available to support water quality sensors, multi-parameter sondes, ADCP's, and other subsurface instruments.
The optional solar marine light has a one to three nautical mile range and securely mounts to the buoy top plate for maximum visibility.

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 […]Read More →
The Chicago Park district is one of the largest municipal park managers in the nation with 8,100 acres of green space spread across 580 different parks. It also manages many indoor facilities, historical landmarks and beaches. At eight of its most popular beaches, the district has used cellular data buoys, for four years, in an effort to more quickly predict E. Coli levels that could necessitate beach closures. Chicago Park […]Read More →
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 […]Read More →
