Features

Compact data buoy

Compact

With an overall 18-inch diameter by 37.5-inch height, the CB-50 can be deployed quickly and easily from a small boat. Fully configured systems typically weigh around 50 lbs.

Marine beacon

Tower

A removable topside foam tower protects the electronics, supports solar marine lights, and offers a convenient lifting point via (3) 5/8” eyenuts.

Buoy deployment pipe

Center Hole

The 5.5” ID center hole is designed to securely house X2-SDL data loggers. Empty canisters are also available for user-supplied electronics.

Data buoy sensor connections

Sensor Connections

The X2-SDL is configured with three sensor ports for connection to industry standard communication protocols including SDI-12, RS-485 and RS-232.

Water quality sonde deployment

Instrument Cage

An optional instrument cage provides a secure mounting location for water quality sensors, multi-parameter sondes, depth sonar and more.

Data buoy navigation 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 buoy

Data Logging

The CB-50 data buoy is designed to accommodate the X2-SDL submersible data logging system, which includes integrated power supply and optional wireless telemetry.

Cellular data buoy

Wireless Communications

The X2-SDL data logger is available with radio-to-shore, cellular and Iridium satellite communications. An integrated antenna mounts securely beneath the tower.

Small durable data buoy

Built to Last

Constructed of cross-linked polyethylene foam with a heavy polymer skin and an indestructible stainless steel frame, the CB-50 is designed for years of service.

Case Studies

Cellular Data Buoys Predict E. Coli

The Chicago Park district is one of the largest municipal park managers in the nation with 8,100 acres of green space spread across 580 different parks. It also manages many indoor facilities, historical landmarks and beaches. At eight of its most popular beaches, the district has used cellular data buoys, for four years, in an effort to more quickly predict E. Coli levels that could necessitate beach closures.

Understanding Lake Erie Walleye Hatches

Lake Erie is described by many as the "walleye capital of the world," but dwindling populations of the fish pose a concern for Great Lakes fishermen. The region's multibillion-dollar commercial and recreational fishing industry relies heavily on walleye, and the last major walleye hatch in Lake Erie occurred in 2003. Hatch sizes since then have been, at best, below average. A six-year period of substandard spawning is unprecedented; worse yet, […]
