USBLs, Beacons and Sub Bottom Profilers

ROMOR has sold and serviced subsea acoustic technology since the 80’s. We feature Applied Acoustics because the company manufactures some of the most reliable mid range products in the industry.


Applied Acoustic has 5 USBL Systems under the EasyTrak name. All of these systems include:

  • All operational equipment, hardware and software
  • Integral pitch, roll and heading sensors to compensate for vessel movement
  • GPS receiving software
  • Robust, lightweight enclosures
  • Intuitive control software, bringing the confidence of professional USBL systems to a wide operator base.

Four commercial versions of the system are available; the rack-mount, vessel based Nexus and Lite, the compact Alpha and Alpha Portable that have a display screen and keyboard housed in a marine grade splash-proof enclosure.

Every beacon Applied Acoustic’s manufactures has been designed to be immediately compatible with almost all industry standard tracking systems operating worldwide.

  • Micro Beacons: Small sized, ideal for divers, short ranges and small ROV’s
  • Mini Beacons: ‘Work-horse’ beacons for towfish and ROV tracking, often used by divers too
  • Midi Beacons: High powered, but compact. Used for long range towfish tracking and AUV positioning
  • Fat Boy Beacons: Ideal for deep water ROV’s and AUV’s
  • Low Frequency Beacons: Long range, deep water applications
  • Seabed Beacons: Large battery capacity for long term deployment often used as reference markers
