The ACR Pathfinder 3 Search and Rescue Transponder (SART) is a crucial safety device designed for maritime search and rescue operations. It is a part of the emergency response system that helps rescue teams locate vessels in distress. When activated, the Pathfinder 3 SART emits a series of 9 GHz radar signals that appear on the rescue vessel's radar screen, allowing it to pinpoint the location of the distressed vessel. This transponder is highly reliable, compact, and rugged, making it suitable for harsh marine environments. It is ideal for use in both commercial and recreational maritime activities.
