Customized wave buoys can be delivered in a range of sizes depending on the application. For drifting applications and other situations that do not require a large power supply, the compact and lightweight NexSens CB-25-SVS buoy is an ideal option.

The CB-25-SVS incorporates the high-accuracy SeaView Systems SVS-603 wave sensor. This is packaged together with data logging electronics in a watertight canister mounted in the center of the buoy under the solar panels. The logger transmits wave measurements wirelessly via integrated cellular or Iridium satellite modem. Wave height, period and direction data are sent to the WQData LIVE web datacenter. The free Basic service allows users to securely access, analyze and export data, as well as send simple email alerts. Subscription-based tiers of WQData LIVE expand the functionality to include advanced reporting, alarms, and data sharing options such as auto export, API and public portal options.

Auxiliary sensor ports with marine connectors on the CB-25-SVS logger canister support GPS units, weather stations, and water quality sondes for added flexibility. The compact buoy has a 46 cm diameter and 13,6 kg. The small size and eye bolts for connecting mooring hardware make it simple to deploy, or the buoy may be sent adrift for ocean research.

For advanced oceanographic measurement systems, the SVS-603 wave sensor can integrate into large NexSens buoy platforms like the CB-950 and CB-1250. These models have large solar panels and power capacity to support continuous measurement with a multitude of sensors such as weather stations, ADCP current profilers and multiparameter water quality instruments.
