Advanced Marine Radar with High-Precision Target Detection

The Si-Tex T941A 4kW 36nm Radar with a 25" dome is designed for marine professionals who demand high-performance navigation and target tracking capabilities. Equipped with true-color radar technology, this system enhances visibility by displaying echoes in different colors based on signal strength. The real-time presentation ensures smooth movement as your vessel changes bearing, while dual-speed antenna rotation enables efficient tracking of fast-moving, close-range targets.

With selectable range scales starting from 1/16 NM, the T941A provides excellent situational awareness. Its automatic tuning maintains maximum sensitivity, with manual override options for experienced users. The warning zone feature alerts you to incoming and departing targets, making navigation safer and more precise. Designed for durability, the waterproof (IPX5) case allows for versatile mounting options, ensuring reliability in harsh marine conditions.

Cutting-Edge Radar Technology for Enhanced Navigation

The T941A radar offers a range of advanced features to support safe and efficient marine operations. The system includes dual-range radar functionality, allowing users to simultaneously monitor both long-range and short-range targets on a split-screen display. The true trail function distinguishes moving objects from stationary ones, clearly identifying vessel movement patterns.

Additionally, the radar supports an optional Automatic Tracking Aid (ATA) to track up to 50 user-designated targets, providing critical data on distance, speed, bearing, and closest point of approach. The optional AIS interface enhances situational awareness by displaying information on up to 100 AIS-equipped vessels, including MMSI number, course, and speed.
