The new Sentinel V is the first product configuration to be released from our next generation line of V ADCP products. This self-contained instrument is available in three profiling ranges: 20m, 50m and 100m.

An integrated 5th beam provides a third vertical velocity measurement and a 5th range to the surface measurement, allowing for enhanced turbulence and waves measurement capabilities.

Teledyne RDI's most popular direct read ADCP. The unit is typically bottom frame mounted and hard wired to shore to provide real time monitoring of coastal currents. Available in 300, 600 and 1200 kHz frequency.

The Sentinel is our most versatile instrument. Thousands of Workhorse Sentinel ADCPs™ are profiling currents around the globe. Customers choose it for its unbeatable precision in shallow waters, its 175-meter profiling range, and unmatched low power consumption for extended deployments. Available in 300, 600 and 1200 kHz frequency.

Researchers and commercial surveyors working in coastal waters saw what our best-selling Sentinel instrument could do, and asked for a version designed specifically for underway current profiling from inshore hydrographic survey vessels. The result - the Mariner ADCP. Available in 300, 600 and 1200 kHz frequency.

Teledyne RDI's new 150 kHz QuarterMaster ADCP has been designed to fill a gap between our 300 kHz Workhorse ADCPs and our 75 kHz Workhorse Long Ranger. This unit offers an extended current profiling range over our higher frequency units, in our proven Long Ranger configuration, and is ideally suited for applications requiring up to 300 meters range. The highly versatile QuarterMaster can also be upgraded to include our bottom tracking option.

The 75 kHz Long Ranger is Teledyne RDI's Sentinel based instrument designed specifically for long range (up to 600m) , long duration (up to six months) autonomous deployments. Teledyne RDI's patented Broadband technology ensures data reliability, providing the peace of mind you need in long-term, deepwater data collection programs.

Teledyne RDI's 300 kHz Long Range Horizontal ADCP (H-ADCP) is an acoustic monitoring system that "looks" out horizontally up to 300 meters from a coastal / offshore structure, or vessel to measure near surface water currents.

Teledyne RDI dominates the offshore oil and gas sector with field-proven instruments designed to facilitate exploration drilling, field development and production. The Ocean Observer offers the greatest profiling range available, combined with Teledyne RDI's proven product reliability. Available in 38, 75, and 150 kHz.

The Ocean Surveyor family of ADCP’s adds a new chapter to Teledyne RDI's unique contribution to the worldwide open-ocean research fleet. The Ocean Surveyor has been installed on more than 250 vessel-mounted ADCP’s around the world. These ADCP’s provide detailed maps of the distribution of water currents and suspended materials through the water column and along the ship's path. Available in 38, 75, and 150 kHz.

The DVS offers you with an exponential leap from your single point current meter to a revolutionary current profiler designed for deep water, moored applications. Discover the many unique benefits that only the DVS can offer - at a price comparable to a single point.

In May 2009, Teledyne RDI purchased the entire line of Conductivity, Depth, and Temperature (CTD) products from Falmouth Scientific Incorporated (FSI), including the patented Non-external Inductive Cell (NXIC), which has already acquired a solid reputation for robust operation in shallow, fouling environments.

This product line delivers exciting and proven technology that is complementary to Teledyne RDI’s ADCP products, and represents a tremendous opportunity to deliver turn-key solutions.
