I'm going to be attending EMT academy in a couple of months and wanted to get some advice on what blood pressure cuff and stethoscope to buy. I don't want to buy cheap ones just to train with and have to buy others for when I'm on scene. I was looking at the Littman Cardiologist Stethoscopes, but I'm not really sure about blood pressure cuff brands. Any help you can give me will be greatly appreciated. Much respect and thanks, Jared Mix
