Underwater ROV Add-Ons

Imaging Sonars allow you to see targets in murky water or over long distances, environments where a camera is limited in its capabilities. They are in some cases the only method of performing inspections or search missions underwater. The 1200ik is the most commonly purchased of our imaging sonar lineup, it is great for short and long-range operations.


Gemini 1200ik Multi-beam Dual Frequency Imaging Sonar for Murky Water Survey and Inspection

  • Integrated Into Controller
  • Duel Frequency Mode
  • 0.1 M to 120 M Range

The Tritech Gemini 1200ik multi-beam sonar operates at two acoustic frequencies, 720kHz for long range target detection, and 1200KHz for enhanced high resolution imaging at shorter range object identification.

The 1200ik ability to maintain a 120° field of view when operating at high frequency is completely unique. Allowing the target to remain within view at all times, even when the object is in the near-field.


Low-visibility Operations

Cameras and diver’s eyes often are unable to effectively search due to poor visibility underwater. An imaging sonar is the best tool to then re-identify the target, since oftentimes side scan data does not produce an exact location (so navigating back to the potential target can be difficult). Once the target is re-identified, the sonar can be used to continue to track the target as you move closer, and when you get close enough, it can even be used to perform the visual verification.



Sonar for Search and Recovery

In Search and Recovery operations, First responders looking for evidence or drowning victims typically sweep an area using side scan sonar, identify potential targets and then investigate those targets to see if it is in fact the victim.


Sonar for Hull Inspection

In inspection operations, particularly in murky water applications, it can be difficult to use just a camera to get an understanding of the condition of a structure.

For example, when inspecting the hull of a ship, you want to see if there are any major defects or corrosion, damage to the coating, zincs, anodes, propeller, check the coating condition, check if the hull needs to be cleaned.
