The set, the picture, the plot — the decision stays yours.

20 lessons across five study days, a ten-question check closing every lesson — 200 questions over the radar surface end to end: radar as a piece of equipment (how it sees, the controls, the limitations and errors), reading the picture and the manual relative-motion plot (CPA/TCPA and the OAW triangle), ARPA as a system (acquisition, vectors, the trial manoeuvre and its errors), and AIS with radar for collision avoidance under the COLREGS. Pass a check (8 of 10) to mark a lesson complete; progress is saved on this device. The radar-plot trainer is built into the plotting lessons.
