A new set of Flip Cards covering the recent (and developing) GMDSS systems which are becoming universal. The cards show equipment and procedures for HF, VHF and MF, including Digital Selective Calling. Seamen preparing for the General Operators Certificate or the Long Range Certificate will find the cards particularly useful, while yachtsmen should also be prepared to acquire the appropriate certificate for future use. Without doubt, the coming system.

50 cards in total.
