Remember that these estimates are for time in transit only and that they do not apply until the product leaves the Fondriest warehouse. As the delivery of your order is beyond Fondriest’s control once your order leaves the Fondriest warehouse, we cannot assume liability for late deliveries, regardless of the delivery method you specify.
Signature Required on Most Deliveries
Most of Fondriest’s shipments contain valuable equipment. If you will not be at the shipping address to accept delivery of your product, consider shipping the item to an address where someone you trust will be available to sign for your package, or accept your package if a signature is not required for the delivery.
Once your order has prepared for shipment or has shipped, we are unable to change the shipping address. Title and risk of loss to all products will pass to you on delivery. If you are willing to assume the risks of delivering your order without a signature, you may authorize Fondriest to arrange for a delivery that does not require anyone to be at the delivery address.
Undeliverable Packages
Occasionally, packages are returned to Fondriest as undeliverable. When the carrier returns an undeliverable package to Fondriest, please contact us to make arrangements for reshipment.
Failed Delivery Attempts
Most of Fondriest carriers make three attempts to deliver a package. After three delivery attempts, the carrier will return the package to Fondriest.
Order Processing
The estimated shipment date on your order is based on product availability, payment processing time, and warehouse processing time and does not include transit time. We do not begin payment processing until Fondriest receives all of the information that is needed and full payment or a full authorization, in the case of credit card or rental orders.
Fondriest will begin payment processing for orders placed on weekends or holidays on the next business day. Business days are Monday through Friday, excluding federal holidays.
Your order for in-stock items that are eligible for same-day shipping must be received before your local time of 2:00 p.m., pending payment processing, for there to be adequate remaining time in the day for your order to be dispatched.
Product Availability
Fondriest makes every effort to ship your product according to the estimated lead times. The estimated lead times are in business days (Monday through Friday, excluding federal holidays). Although Fondriest makes every effort to ship your order according to the lead time provided, shipping dates may change due to changes in supply. If the lead time changes, Fondriest will contact you via email and provide a revised shipping estimate.
Fondriest makes every effort to supply the products you order, but there may be occasions when Fondriest confirms orders and later learns that it cannot supply the products, either at all or in the quantities ordered. Although rare, these occasions can include when Fondriest learns that the products are no longer being manufactured or they otherwise become unavailable, when Fondriest cannot source components for the configuration you ordered, or when there was a pricing error at the Fondriest Online Store.
In those circumstances, Fondriest will inform you and, if you are interested, Fondriest may suggest alternative products that may meet your needs. If you do not wish to order alternative products, Fondriest will cancel your order for products that cannot be supplied and for any other products that you no longer wish to order as a result, and will issue a refund.

- Integrated 15-watt solar panels for 45-watts of solar charging
- Three 4" diameter sensor holes with female NPT threads for sensor deployment
- Topside plate supports solar marine light, weather stations, and other sensors
The NexSens CB-450 Data Buoy is designed for deployment in lakes, rivers, coastal waters, harbors, estuaries and other freshwater or marine environments. The floating platform supports both topside and subsurface environmental monitoring sensors including weather stations, wave sensors, thermistor strings, multi-parameter sondes, Doppler current profilers and other monitoring instruments.
The buoy is constructed of an inner core of cross-linked polyethylene foam with a tough polyurea skin. A topside 20” tall stainless steel tower includes three 15-watt 12VDC semi-flexible solar panels, and a center 10” ID x 19.5” tall instrument well accommodates batteries, data loggers, sensors, and more. Three 4” pass-through holes with female NPT bottom threads allow for quick connection of instrument deployment pipes and custom sensor mounts. The stainless steel frame supports both single point and multi-point moorings.
The CB-450 Data Buoy is optimized for use with NexSens X3 data loggers. Wireless telemetry options include global 4G LTE cellular, Iridium satellite, and global 4G LTE cellular with Iridium satellite fallback. Compatible digital sensor interfaces include RS-232, RS-485 and SDI-12. Each sensor port offers a UW receptacle connector with double O-ring seal for a reliable waterproof connection. For custom integrations, CB-PTL pass through and CB-MCL wet-mate data well lids are available.

Questions & Answers
Are the buoys safe for coastal deployment?
While we generally recommend the CB-650 and larger data buoys in coastal environments, we do have many customers that have successfully deployed the CB-450 in coastal environments.
Can this model be deployed for long periods of time?
Yes, the CB-450 is designed for seasonal or year-round deployment. The system offers autonomous power with integrated battery harness and solar charging.
Can data be retrieved offshore?
When integrated with the X2-CB data logger with Wi-Fi, cellular, Iridium satellite, or radio telemetry, data is accessible in real-time via the WQData LIVE secure web datacenter.
While deployed, can the buoy be wirelessly troubleshooted?
When integrated with a wireless modem or X2-CB buoy-mounted data logger with wireless communications, the system can be accessed for remote configuration and/or troubleshooting.
How can I ensure buoy stability?
Buoy stability is dependent on a number of factors including instruments attached, mooring design, water currents, and regional weather conditions. It is recommended to examine the buoy upon deployment, adding ballast weight and adjusting the mooring as needed. Given that each deployment is unique, be sure to communicate with NexSens application engineers for optimal stability.
Under what conditions would I need to remove the CB-450 data buoy?
Freezing and periodic maintenance are the two most common reasons to remove a buoy from the water. A large number of buoy deployments are seasonal, so customers will commonly remove the buoy in the fall and redeploy in the spring. For year-round buoy deployments, NexSens recommends pulling the buoy at least once for cleaning and maintenance inspection.
The potential for large storms and river debris flows are also good reasons to pull a buoy in order to prevent any ensuing damage. NexSens recommends integrating a GPS in situations where debris loads or other circumstances have the potential to move the buoy, like in a river or coastal setting.
How do I know if I need an anti-rotation collar on the instrument cage?
An anti-rotation collar is not necessary if the buoy is deployed on two point mooring and no instruments are attached to cage. Anti-rotation collars are recommended for single point moorings or when instruments are attached to the cage. This provides an added strength member and prevents the potential for cable tangling.
Can the solar panels be individually replaced in the field?
The solar panels feature a waterproof 2-pin connector that plugs into a 3-way splitter on the solar tower. In the event of a failure, the solar panel can be swapped out in the field.

Restoring the Heart of the Everglades Starts at Lake Okeechobee
Standing on the southern bank of Lake Okeechobee, central Florida, sawgrass bows to the relentless wind, and the white caps of wind waves scour the grey line of the horizon. Lake Okeechobee is the second-largest freshwater lake in the contiguous United States–so vast it acts like an inland sea. Yet it is also breathtakingly shallow: only nine feet, on average. “The lake is the heart of the entire Greater Everglades ecosystem,” says Dr. Anna Wachnicka, a Principal Scientist at the South Florida Water Management District (SFWMD). “It’s an amazing but highly dynamic and highly complex system.” But after centuries of agricultural and urban expansion and changing environmental conditions, Okeechobee has been heavily degraded.
Muskingum Watershed Conservancy District Deploys Five New Real-Time Data Buoys
Water resource management in the Muskingum River Watershed dates all the way back to 1913 , when a record-breaking flood devastated the area. The event became known as the Great Flood of 1913, resulting in 650 residents dead and miles of damaged land. In hopes of minimizing the impact of future floods, the Muskingum Watershed Conservancy District (MCWD) was formed. Focused on flood control and water conservation, 14 dams were constructed throughout the watershed over the following years. These dams created reservoirs that continue to play an important role in flood management, but have also become recreational hubs for residents and visitors.
From Panama to Patagonia: Advancing Water Monitoring Across Latin America with Base Flow
Across Latin America, access to reliable environmental data is becoming increasingly important for managing water resources, supporting energy production, and protecting ecosystems. From hydropower reservoirs facing climate-related variability to rapidly developing coastal areas, getting continuous, high-quality measurements to guide planning and safeguard natural systems has never been more important. In many remote or dynamic environments, this means deploying resilient monitoring platforms that can operate autonomously and deliver data in real time. Base Flow was founded in 2013 with the goal of protecting water resources by providing top-quality environmental monitoring equipment.
