SmartFind S20 SART

The McMurdo SmartFind S20 is a radar‑activated Search and Rescue Transponder (SART) that automatically responds to X‑band radar signals, providing a distinctive ‘dot’ pattern on rescuers' screens; its defining feature is a 96‑hour standby battery life. The supplied category identifies the equipment as Radar SART, and it is normally installed on the bridge, radio station or survival-craft equipment position appropriate to the listed type. In that listed role, its primary purpose is to provide distress, safety, operational communication or search-and-rescue locating capability. VHF, MF/HF, satellite terminals, EPIRBs and SARTs use different communication paths and emergency roles, so testing must follow the specific approved procedure. The model designation identifies the listed configuration, but no additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. The source metadata also states capacity: 9 GHz / 96 hrs. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
