As a current profiling system, the Argonaut-XR offers exceptional value for near shore
deployments. Its small size, rugged build quality, and flexible system architecture make it very attractive for both real-time operation as well as autonomous deployments. The basic
autonomous system includes an external battery pack, internal recorder, compass/tilt sensor, pressure and temperature sensors. Adding on options such as a non-directional wave package, the SeaBird MicroCAT CT sensor, or a YSI multi-parameter water quality probe makes Argonaut-XR the centerpiece of a complete oceanographic system.

Since its introduction, the Argonaut-XR has differed from other Doppler current meters in a very special way. The size and extent of the XR’s sampling volume is dynamic and can change with changing water level. This feature has been referred to in the past as the AutoTide feature. In addition, the autonomous configuration of this product has 10 current profiling cells as a standard feature. This feature is in addition to the dynamic, single cell. The powerful combination of a single cell using AutoTide and 10 classic cells is referred to as MultiCell.
