Features

Versatile

Versatile

The CB-250 is light enough to be deployed from most small boats, yet it offers adequate power and charging for rigorous instrument sampling and data transmission.

Self-Powered

Self-Powered

Three integrated 15-watt solar panels are angled and evenly spaced around the buoy to capture sunlight from any direction and provide adequate battery charging.

Data Well

Data Well

A 10-inch diameter by 19.5-inch tall data well provides a watertight housing for batteries, data loggers, sensors, and other hardware.

Connections

Connections

The data well lid provides pass-through connections for sensors, power, venting, and more. When integrated with the optional NexSens X2-CB data logger, the system is truly plug-and-play.

Pass-Through Ports

Pass-Through Ports

Three 2-inch pass-through ports allow for sensors to be mounted underwater while securely routing the cable. Instrument deployment pipes and custom sensor mounts attach to 4-inch NPT bottom threads.

Solar Beacon

Solar Beacon

The optional solar marine light has a one to three nautical mile range and securely mounts to the buoy top plate for maximum visibility.

Data Logging

Data Logging

The X2-CB data logger replaces the standard pass-through data well lid for turnkey systems. Alternatively, 3rd party data loggers can be integrated by the user inside the data well.

Wireless Communications

Wireless Communications

Communication options using the X2-CB data logger include Wi-Fi, radio-to-shore, cellular, and Iridium satellite.

Case Studies

Sturdy Little Buoy, Tremendous Predictive Power

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 […]

Protecting Ohio River Wildlife

A complex series of locks and dams up and down the Ohio River enable interstate commerce, travel, and recreation. But maintaining a usable pathway for watercraft comes at a cost. The inevitable byproducts of disrupting the river’s natural systems are a threat to local wildlife. To combat this, the US Army Corps of Engineers (USACE) uses complex monitoring and response technology designed to minimize the negative impacts of dredging on […]

Submerged Sensors of Sebago Lake

Sebago Lake is the second largest lake in Maine—one of the only lakes in the nation with clean enough water for use by a drinking water facility without filtration requirements. Residents of the Greater Portland area are the beneficiaries, and they are invested in maintaining their lake's health. A joint project between the Portland Water District (PWD) and Saint Joseph’s College of Maine (SJC) assisted by the NexSens team submerged […]
