Thrane & Thrane introduces the new SAILOR RT5022 VHF DSC, fulfilling and even exceeding GMDSS requirements. The SAILOR RT5022 includes a very powerful transmitter, a very sensitive and accurate receiver and a built-in loudspeaker. As the first VHF ever, the SAILOR RT5022 can store and replay incoming calls. This facility increases the safety at sea as a missed message just can be heard again.
