CB-1250 Data Buoy

The CB-1250 offers increased flotation and solar charging for heavy or power-hungry sensors while still maintaining a relatively small footprint.

Features

Powerful



The platform integrates three 71-watt solar panels on the tower with space for up to four 28 A-Hr batteries in the instrument well.
