NEXSENS CB-950 Data Buoy
Overview
The CB-950 data buoy is constructed of an inner core of cross-linked polyethylene foam with a polyurea coating that provides 950 lb. buoyancy. A stainless steel internal frame provides topside lifting eyes and subsurface mooring eyes for single- and multi-point mooring. An integrated data well accommodates internal batteries, which are recharged by (3) 46-watt solar panels mounted on the buoy tower. The data well lid is available as a NexSens X2-CB buoy-mounted data logger or as a standard lid with included pass-through fittings.

Instrument Cage Installation
Follow the included CB-CCA quick start guide to attach the instrument cage to the buoy frame.
Solar Tower Connection
- 1 Remove the included clevis pins from the (3) tower mount hubs.
- Insert the tower legs into the tower mount hubs.
- Re-install the clevis pins to secure the solar tower.
- It is recommended to apply a zip tie through the loop closure for added security.
Mooring Configurations
To develop an effective mooring strategy, a variety of application-specific criteria (water level fluctuations, currents, and wave action, debris loads, etc.) must be thoroughly reviewed prior to deployment. NexSens does not endorse any particular mooring strategy for any specific application. For more information on mooring configurations, follow the link provided: nexsens.com/mooringdb
Safe Deployment
Warning: Always follow safe marine and boating practices. Heavy anchors,
ballast weights, and chain require careful maneuvering. Small boats with
limited lifting equipment and boat clutter can be unsafe. Care must be taken
during deployment to maintain a clean and safe environment.
Saltwater Deployment
Sacrificial zinc anodes should be used whenever a buoy is deployed in a
saltwater environment to prevent corrosion. These zinc anodes must be
inspected and replaced as needed.
Ballast Weight & Stability
To prevent the overturning of a CB-950 buoy system and to ensure that it is
stable in the water, additional ballast weight may be needed. The buoy’s
center of gravity is near the water surface without instruments connected. Any
weight added above the water surface must be appropriately counterbalanced by
adding ballast weight below the surface. For more information regarding top-
side and ballast weight, follow the link provided:

The buoy data well is not rated for submersion, so proper ballast weight is critical to ensure that the buoy does not overturn, including when the buoy is subjected to additional loading (e.g. high wind/waves, periodic snow/ice loads, etc.).
