Maritime search and rescue transponder - mandatory equipment Global Maritime Distress System (GMDSS).This product can be both life-saving means of the ship and boat rescue tool.According to the rules of the GMDSS, radar transponder is required to be installed on ships with a total tonnage of 500 register tons, in the amount of RLS, and more than 500 reg. in an amount of two tons.Devices on the requirements of the register must be located one - in the wheelhouse of the vessel and the second should be in the main lifeboat.
McMurdo S4 Rescue SART
Designed to be stored in a survival craft or as a carry off device,
the rugged S4 Rescue SART is buoyant and waterproof to a depth of 10m.
When it detects a radar signal from another vessel or aircraft, the S4
Rescue SART’s 9GHz X-band Radar transceiver will automatically transmit a
response signal which will appear on the other vessel’s radar display
as a series of 12 dots, pinpointing your location. An LED and buzzer
indicates when the S4 has detected a radar signal and transmitted a
Once activated the S4 Rescue SART may be suspended inside the
survival craft or mounted in an elevated position using the integrated
The S4 will only transmit when it detects an incoming radar
pulse - after 15 seconds it will drop to standby mode, conserving
battery life and ensuring operation in excess of 96hrs.
