2-Channel Precision Direction Finder The RT-202 CrewFinder features compact, robust design and permits fast, efficient recovery in the event of a man overboard incident despite heavy seas and poor visibility. The RT-202 monitors the 121.5 MHz international distress frequency and alarms the crew if an emergency signal is received. The bearing of the source is shown on the LED screen to lead the crew directly to the person in distress. The “selective squelch” function prevents false alarms caused by interference or other radio signals. The RT-202’s compact antenna also makes it ideal for installation on smaller vessels and lifeboats as well as for landside applicat

SAR (Search and Rescue) and “Man overboard” applications A “man overboard” emergency is always terrifying – for the person in distress as well as for crew members. Under poor conditions, it can be almost impossible to find someone in the water and whether or not the individual is found is a matter of luck. To make matters worse, search and rescue services are usually not available due to the lack of a seamless infrastructure or SAR personnel cannot reach the person in the water before it is too late. The RT-202 makes it possible to reach and rescue overboard crew members quickly and easily despite...
