CB-25-SVS Wave Buoy
The CB-25-SVS Wave Buoy offers the latest in real-time wave observations in a compact, affordable, and easy to deploy platform with flexible communications and optional expansion with additional sensors.
With 18” (46 cm) hull diameter and less than 30 lb. (13.6kg) weight, the CB-25-SVS can measure waves 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.
Integrated Wave Sensor
Wave height, period and direction are measured with the industry-leading SeaView Systems SVS-603HRi inertial wave sensor built directly into the waterproof buoy electronics.
The CB-25-SVS data buoy includes the X2-SVS wave data logger with integrated power supply, wet-mate marine connectors and optional wireless telemetry.
The X2-SVS wave data logger is available with 4G cellular or Iridium satellite communications. The integrated antenna is nestled securely beneath the solar top.
Auxiliary sensor ports with wet-mate connectors on the X2-SVS wave data logger allow for optional expansion with GPS receivers, meteorological stations, water quality sondes and other sensor types.
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 a small instrument cage can be connected.
The optional solar marine light has a one to three nautical mile range and securely mounts to the buoy top plate for maximum visibility.
Built to Last
Constructed of cross-linked polyethylene foam with a heavy polymer skin and an indestructible stainless steel frame, the CB-25-SVS is designed for years of service.

Two solitary data buoys floating off the storm-tossed Lake Superior shore near Munising and Granite Island were sudden stars in 2017. That October, they captured the largest waves ever measured on the Great Lakes—each 28.8-foot high—during a storm that claimed the lives of two people swept off rocks. This attention-getting event shows how buoy data help managers and the public comprehend the otherwise unimaginable force of a wild Lake Superior […]Read More →
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 →
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 →
