Difference between SART and EPIRB
SART 
SEARCH AND RESCUE TRANSPONDER
It is a vital machine during distress for it helps in locating the position of the vessel in case it goes off-track.
They are the most supportive machines in case of an unprecedented emergency.
It operates on the 9GHz frequency band (9.2 to 9.5 GHz) and generates a series of blips on the radar it is interrogated by (3 cm/X Band radar)
Battery Requirements
In standby condition, operational for 96 hours
In working condition, operational for 08 hours
Battery should be replaced every 2 to 5 years
Operable in temperature between -20 deg to 55 degrees.
The AIS-SART is a self-contained radio device used to locate a survival craft or distressed vessel by sending updated position reports using a standard Automatic Identification System class-A position report.
  EPIRB
EMERGENCY POSITION INDICATING RADIO BEACON
  A device to alert search and rescue services (sar) in case of an emergency out at sea. It is tracking equipment that transmits a signal on a specified band to locate a lifeboat, life raft, ship or people in distress.
It is mandatory to carry one EPIRB on every ship and two EPIRBS for all Registered ships (and other types of vessels.)
The device contains two radio transmitters, a 5-watt one and a 0.25-watt one, each operating at 406 MHz, the standard international frequency typically signalling distress, 406MHz.
Battery
12 Volt battery
48 hours of transmitting capacity
Normally replaced every 2 to 5 years
