The Gemini 1200ik is a powerful addition to the renowned Gemini range of sonar systems. It offers two operational frequencies, allowing users to switch between low and high frequencies depending on their requirements. The 720kHz low-frequency setting is ideal for long-range target identification and obstacle avoidance, while the 1200kHz high-frequency setting provides detailed multibeam images, perfect for close-range inspections. The frequency switching can be configured to occur automatically at a specific range or manually as needed.

What sets the Gemini 1200ik apart is its unique capability to maintain a 120-degree field of view across both frequencies. This feature ensures that targets remain in view even when operating at high frequency and short range, providing comprehensive imaging coverage.

Through significant engineering advancements, the Gemini 1200ik achieves an impressive range resolution of 2.4mm and an effective angular resolution of just 0.12. This level of precision enables precise and detailed imaging of underwater environments.

When paired with the Diver Mounted Display, the Gemi 1200ik offers real-time imaging to divers, even in low-visibility conditions. The high-resolution diver display enhances situational awareness and facilitates efficient operations.

Experience the cutting-edge capabilities of the Gemini 1200ik multibeam imaging sonar and unlock new possibilities for underwater exploration and analysis.
