Q&A
The CB-50 is light enough to ship in a box rather than on a pallet, which significantly reduces freight costs. It also deploys easily, as no large boat or crew is necessary. Once deployed, relocating the system is as easy as lifting the anchor, moving to the appropriate location, and dropping the anchor.
Instead of using solar charging, the CB-50 buoy supports the X2-SDL Submersible Data Logger that is powered by sixteen user-replaceable D-cell alkaline batteries. When outfitted with wireless telemetry, the data logger transmits battery voltage as a diagnostic parameter to take the guesswork out of battery replacement frequcency (typically necessary every several months). The integrated X2-SDL submersible data logger is compatible with most water sensors on the market, making it a very flexible platform for short-term, portable, and even seasonal projects.

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. Chicago Park […]

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 multi-billion-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, […]
