DRS25A-NXT (scanner unit only)
200W Solid-State Doppler Radar with Target Analyzer and Fast Target Tracking
Target Analyzer function utilizing Doppler technology spots hazardous targets instantly!
The NXT series are 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 further away from your vessel. Target Analyzer improves situational awareness and can increase safety by showing you which targets to look out for. New Hi-Power 200W.
Target Analyzer ON - Two approaching targets are depicted clearly in RED when Target Analyzer is ON.
Target Analyzer OFF
Hazardous targets are displayed in bright red
Target Analyzer clearly shows targets close to structures
Rain mode
When the 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 vessels 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.
