With an 53.34cm hull diameter and less than 20KG, the CB-75 is ideally suited for tethered moorings.
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-75 data buoy is designed for integration with the X3-SUB submersible data logger with integrated power supply, wet-mate marine connectors and optional wireless telemetry.
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 X3-SVS 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 stainless steel instrument cage provides ballast weight and also includes a mooring eye.
Two additional sensor ports on the X3-SVS wave data logger allow for optional expansion with GPS receivers, meteorological stations, water quality sondes and other sensor types.
The optional solar marine light has a one to three nautical mile range and securely mounts to the buoy top plate for maximum visibility.
Constructed of cross-linked polyethylene foam with a heavy polymer skin and an indestructible stainless steel frame, the CB-75 is designed for years of service.
