Vorfreude manufactured this cardiology stethoscope. It comes with a lifetime warranty, four replacement earpieces, and 1 extra diaphragm. It also comes with a pen light and batteries. The stethoscope is latex free, PBA free, and is stainless steel. It has been sterilized at the factory.
I had never used a cardiology stethoscope before, as I worked in in-patient acute care. This is by far the clearest stethoscope I have ever heard. If you are looking for one for your bug out bag, I definitely recommend this.
