I was interested in electronics but found it difficult to work 8 hours, go to school 8 hours, and study at least 4 hours a day, and I burnt out. I researched all the services and found the Coast Guard electronic technicians trained on everything, and they only specialized between aircraft and all others.
So I joined to get electronics school where I could work on everything from small boats to large cutters, buoy tenders, ice breakers, Loran (long-range aids to navigation), lighthouses, shore stations, communication stations, and remote aids/high sites.
