In 1995, AML pioneered time-of-flight sound velocity. In March of 2008, we launched the market’s first – and only – field-swappable sound velocity sensor.

Today, we are the vendor of choice for sound velocity measurement for a wide range of marine survey organizations and manufacturers of multi-beam, single-beam, intrusion detection, and USBL / LBL positioning systems.

Have a Base•X₂ SVP or Minos•X SVPT for profiling and a Micro•X SV for SV correction at the multibeam transducer? The SV•Xchange sensors on each instrument are interchangeable.

Want to calibrate the SV•Xchange™ on the Micro•X SV installed at the multibeam transducer? Unscrew SV•Xchange™ and leave Micro•X installed. If you have a spare sensor, screw it on and you are ready to resume surveying.
