QUICK START GUIDE
CB-1250 DATA BUOY PLATFORM
Figure 1: CB-1250 Data Buoy Overview
Overview
The NexSens CB-1250 data buoy platform is
constructed
with
a
polyethylene foam hull with polyurea coating that
provides 1250 lb buoyancy. The buoy has a
corrosion resistant, stainless steel internal frame
with topside lifting eyes and subsurface mooring
eyes for connection of single-point and multi-
point mooring systems.
An integrated data well located within the buoy
hull accommodates batteries and electronics. The
data well lid is available as a NexSens iSIC-CB
data logger assembly or as a standard lid with
pass-through fittings for use with user-supplied
electronics. Internal batteries are recharged by
(6) 30-Watt solar panels mounted on the buoy
tower, which also supports an optional LED
beacon, radar reflector, and RTU-R/C/I radio,
cellular or Iridium satellite telemetry module.

Assembly
The main components of the CB-1250 data buoy
platform are assembled at the time of shipment.
Installation of accessories may be required. Quick
instructions are provided in this guide. Visit the
online Knowledge Base for more information (see
Additional Information section).
Instrument Cage
The instrument cage is connected to the buoy
using a CB-CCA cage clamp accessory. Reference
the instructions provided with the clamp for
installation. Welding the cage and/or installing
additional security straps is also recommended
for use in rough water.
