Sentinel: 300 kHz - 600 kHz - 1200 kHz
Mounted at a fixed location for self contained operation (internal memory and alkaline battery pack). Records data internally during 6-12 month duration. (sometimes used as a backup for a real-time link) ; Windows-based software for planning, deployment, recovery, data display.
For over twenty years, Teledyne RD Instruments has been the preeminent supplier of Acoustic Doppler Current Profiling (ADCP) instrumentation for open ocean applications. RDI’s vessel-mounted Ocean Surveyor family of ADCPs continues to raise the bar, collecting detailed maps of the distribution of water currents and suspended materials through the water column and along the ship’s path—at depths and resolutions previously considered unattainable. In real time, the ADCP is also used to aid in situ decision-making, to adapt field operations, and to understand current regime characteristics.
 - Versatility: Direct reading or self contained, moored or moving, the Sentinel provides precision current profiling data when and where you need it most.
 - A solid upgrade path: The Sentinel has been designed to grow with your needs. Easy upgrades include pressure, bottom tracking, and directional wave measurement.
 - Precision data: Teledyne RDI’s patented BroadBand signal processing delivers very low-noise data, resulting in unparalleled data resolution and minimal power consumption.
 - A four-beam solution: Teledyne RDI’s patented 4-beam design improves data reliability by providing a redundant data source in the case of a blocked or damaged beam; improves data quality by delivering an independent measure known as error velocity; and improves data accuracy by reducing variance in your data.
 - Budget an issue? This product is available in our new value priced basic Express Configuration. Same broadband quality, with basic current profiling capabilities

Monitor: 300 kHz - 600 kHz - 1200 kHz
Mounted at a fixed location for acquiring and displaying data in real-time; Available in 3 frequencies varying from 15m to 100m reach for measuring water currents; uses direct cable connection to external power supply and PC computer and operation at great depth.
The Monitor is Teledyne RD Instruments’ most popular direct-reading Acoustic Doppler Current Profiler. The unit is typically bottom frame-mounted and hard-wired to shore to provide real-time monitoring of coastal currents.
The Monitor’s high data accuracy and reliability make it a favorite for deployments in high-volume traffic areas such as ports and harbors, where the data is often integrated into a Vessel Traffic Monitoring System.
 - Extreme accuracy and reliability: The Monitor is ideally suited for the most demanding environments, including high traffic areas such as ports and harbors.
 - Versatility: This direct reading unit can easily be upgraded to tackle a wide variety of coastal applications. Typical upgrades include pressure sensor, external battery pack, bottom tracking, and directional wave measurement—a single instrument can do it all!

Mariner: 300 kHz - 600 kHz - 1200 kHz
Researchers and commercial surveyors working in coastal waters saw what RDI's best-selling Sentinel instrument could do. So they asked  for a version for underway current profiling from inshore hydrographic survey vessels. Mariner is the result. It gives fine along-track resolution thanks to RDI’s superior low-noise data, including bottom tracking. And it’s easily teamed with the vessel’s DGPS input to integrate ADCP readings with precise position information.

Ocean Surveyor: 38 kHz - 75 kHz - 150 kHz 
The Ocean Surveyor family of ADCPs™ adds a new chapter to RDI's unique contribution to the worldwide open-ocean research fleet. More than 250 vessel-mounted ADCPs™ have been installed around the world. These ADCPs™ provide detailed maps of the distribution of water currents and suspended materials through the water column and along the ship's path. In real time, the ADCP™ is also used to aid in-situ decision making, to adapt field operations, and to understand current regime characteristics.

Ocean Observer: 38 kHz - 75 kHz - 150 kHz 
RDI dominates the offshore oil and gas sector with field-proven instruments designed to facilitate exploration drilling, field development and production. RDI acoustic Doppler systems and software have been chosen by the majority of offshore operators worldwide to support their exploration drilling programs. This support is provided for station-holding, riser deployment and monitoring, ROV operations and marine operations - and the data is all gathered and displayed in real time to enable crucial operational decisions to be made. The user selects between RDI's high resolution or long range settings for the greatest flexibility in operation.

Horizontal ADCP (H-ADCP): 300 kHz - 600 kHz
Mounted at a fixed location looking across the flow, to give an ongoing horizontal profile of 1 to 128 independent measurements, depending on user choices. Excellent range and resolution are combined in one instrument. As always, RDI's strict engineering standards result in delivery of the highest quality data from a robust package.
