The brand new acoustic profiler joining the SeaGuard family. It features innovative development of the acoustic profiling capacity and an exceptional ability to collect high quality current information on moving and tilting moorings. Available as a self-recording instrument, it also integrates unique real time features to meet your application needs.
The SeaGuardII is a smart data hub that combines the SeaGuard electronics with the advanced management firmware of Aanderaa SmartGuard data hub.
SeaGuardII DCP is a 600kHz frequency profiler with multi-sensor capability. By design, we offer increased deployment time, optimized configuration flexibility and unique features to cope with demanding upper ocean environments.
Optional parameters are available using Aanderaa range of smart sensors that include temperature, pressure, conductivity, oxygen, wave, tide and turbidity. In addition the SeaGuardII has 4 analog inputs, 2 serial ports with power control and direct connection for real time data transmission unit.

|
||
3. Requires pressure sensor 4117
|
||
4. Optimal selection of the the best 3-beams conbination to avoid interference and beam failures
