Teledyne Pinnacle ADCP

With the Pinnacle 45, TRDI reaffirms its position as the forefront leader in deep water current profiling technology.

Drawing from the remarkable 20-year success of its industry-standard Long Ranger ADCP, the Pinnacle ADCP 45 elevates technology and capability to unprecedented levels, catering to both research and operational applications.

Rated for depths of up to 2000 m, the 45 kHz phased array Pinnacle ADCP offers a 1000 m current profiling range alongside reduced size and weight, a revolutionary swappable configuration, and a host of impressive new features and product enhancements.

  • Swappable Configuration: Convert from self-contained to real-time without an additional purchase
  • Deep Water Profiling: up to 1000m, rated to 2000m depth.
  • Phased Array: 20° phased array transducer reduces size and weight and decreases missing data
  • Versatile: Deployable from offshore platforms; moving boats; or seafloor, subsurface or surface buoys
  • Easy Data Access: Redundant MicroSD memory cards for added data security—one resides in the electronics for data download and another in the battery compartment allowing for easy data access.
  • Advanced Monitoring: Health monitoring and leak detection provide users with the peace of mind that their system is operating as intended.
  • Adaptable: Independent or interlaced long range and high-resolution modes allow users to optimize their system for unique deployment requirements, at ranges of up to 1000m, offering the best of both worlds in a single instrument.
  •  Continuous Sampling: The Pinnacle ADCP’s 4 beams ping simultaneously (as opposed to individually), allowing for simultaneous sampling of a 1000m current profile.
  • Compass Enhancements: Pinnacle includes both heading field calibration and magnetometer data, allowing you to utilize either or both and to turn your mooring faster.
  • Deployment Status Indicator: External LED light ensures you know the system is operational when deployed.
  • Increased Data: 20° phased-array beam allows you to measure within 6% of range to surface (air/sea or bottom), closing the gap on missed data.
  • Rugged and Robust: Independent main electronics housing and battery compartment and a no metal in contact with the water designed housing and transducer limit the risk of damage from leaks.
  • Long Life: Alkaline or lithium battery compatible, with 18-month deployment durations possible on 4 Li batteries.
  • Versatile: Collect stored or real-time data from stationary or moving platforms, including rigs, vessels and moorings.
  • Mooring Compatibility: The Pinnacle ADCP's hardware fits into most existing mooring designs offered by key manufacturers.
