Why these add-ons

Proven payloads, ready to integrate

The catalogue runs deep — but a handful of components do the heavy lifting on most missions. These are the upgrades our customers reach for first, each one field-proven and ready to bolt onto the platform you already run.

Blue Robotics T200 thruster
⚡ Propulsion · Blue Robotics

The thruster the industry standardised on

The T200 is the most widely deployed ROV thruster in the world — the propulsion behind the BlueROV2 and thousands of custom builds. When you need more muscle, the T500 delivers over three times the thrust from the same trusted design language.

  • T200: 6.7 kgf max thrust · T500: 16.1 kgf
  • 300 m depth rated, brushless and field-serviceable
  • Matched Basic ESCs for plug-and-play ArduSub / BlueOS control

Live output Live SonarView 3D bathymetry replay from a Cerulean Omniscan sonar
📡 Acoustics · Cerulean Sonar

See the seabed in real time

The Omniscan family turns any ROV or survey boat into an imaging platform — forward-looking navigation, side-scan, and live 3D bathymetry rendered straight into SonarView. This is real captured output: a dockside channel reconstructed as a point cloud while the vessel passes overhead.

  • Forward-looking, side-scan & multibeam options
  • Real-time 3D point cloud and depth contours in SonarView
  • Validated mounting kits for BlueROV2 and BlueBoat

Hydromea LUMA X-UV underwater optical modem
📶 Comms · Hydromea

Cut the tether — go optical

Hydromea's LUMA optical modems carry data wirelessly through water at speeds acoustics can't touch — up to 10 Mbit/s, fast enough for live Full-HD video. The UV variant shrugs off ambient daylight for shallow-water work, and the deepest units are rated to 12,000 m.

  • LUMA 100 / 500 / X / X-UV across the range
  • Up to 10 Mbit/s — true wireless video relay
  • Pairs with the D-FIN controller & DiskDrive thrusters
View underwater comms →
Water Linked DVL A50 and A125 Doppler velocity logs
🧭 Navigation · Water Linked & Cerulean

Hold position to the centimetre

A Doppler Velocity Log turns a drifting ROV into a stable, surveyable platform — locking station against current and enabling dead-reckoning where GPS can't reach. Add USBL tracking and you can place the vehicle on a chart in real time, topside.

  • Water Linked DVL A50 (0.05–50 m) & A125 (0.05–125 m)
  • Cerulean Tracker 650 DVL and ROVLe / Omnitrack USBL
  • Station-keeping and geo-referenced video on the BlueROV2
