Furuno DRS25A NXT Solid-State Doppler Radar For TZT/TZT2/TZT3

The NXT chapter in radar technology

Furuno NXT Solid-State Doppler Radars utilize Doppler technology to ensure the safest navigation. The NXT series features Target Analyzer, Fast Target Tracking and Auto Target Acquire function to offer optimal detection and sensitivity of hazardous objects. Combined with RezBoost technology, the NXT Radars have no equal in spotting and tracking targets moving around your vessel efficiently with high resolution.

The NXT series is the first Radars in the world to use FURUNO’s exclusive Target Analyzer function. Targets that are approaching your vessel automatically change colour to help you identify potentially dangerous targets. Green echoes are targets that stay stationary or are moving away from you, while red echoes are hazardous targets that are moving towards your vessel. Echoes dynamically change colours as targets approach, or get farther away from your vessel. Target Analyzer improves situational awareness and can increase safety by showing you which targets to look out for.

Rain Mode

When rain mode is on, rain echoes are shown in blue. This mode is particularly useful as it has the capability to detect targets masked by rain clutters.

Fast Target Tracking and Auto Target Acquire function

With Fast Target Tracking activated, it only takes a few seconds for a vector to be displayed once the target is selected, manually or automatically with the Auto Target Acquire function.

When the Auto Target Acquire function is on, approaching targets within 3NM range from own ship, which are potentially hazardous, are automatically acquired by Doppler calculation and will trigger an alarm. Together, Up to 100 targets can be acquired simultaneously, increasing considerably the safety and simplifying estimation of other vessel’s course and speed. (TCPA setting required)

Bird Mode

NXT Radars feature a new bird mode that helps you identify birds gathering around schools of fish at the sea surface. Bird mode adjusts the gain and sea settings automatically for optimal visibility.

RezBoost Beam Sharpening

Furuno’s exclusive RezBoost technology has been incorporated into the NXT radar units for enhanced resolution and impressive performance. With RezBoost set to MAX, the sharpness offers an incredibly detailed image with more targets and less clutter.
