Very good to practice the operation of DSC controller and Funkkgerät. For each incident on board there are 2-3 small exercises. In addition, free practice is also possible. Very useful is the function to record his own radio messages and play it back while the solution is displayed. This is not imm textbook for the voice patterns, but realistic. Even the practice dictates you can practice very well with the program, it contains all 27 radio messages, one of which comes off in the test. It is rounded to the test with the questionnaire.
