Features

The SEP-500 EPIRB complies with CCIR, RTCM, COSPAS-SARSAT and GMDSS performance standards of IMO with transmitting frequencies of 406MHz/121.5MHz.
The SEP-500 receives GPS information and it transmits more accurate distress position than the EPIRB without GPS. This makes RCC(Rescue Coordination Center) perform prompt search & rescue operation. 

• Fully GMDSS compliant
• Global alert via COSPAS-SARSAT satellites
• Exact location faster than standard
• Next generation in marin safty electronics
• Internal GPS allows position updates
