Stethoscope, which is the better? Littman Cardiology III or Littman Cardiology STC?

The Cardiology STC and the Master Cardiology Stethoscope are both great. It takes some practice to the the hang of the pressure to apply to the head to change frequency, but these are both great. I had a Cardiology III for many years. They are rugged old work horses. You can’t go wrong with either of the new designs if you can afford them. Most places that sell them will let you test drive them before you buy. You should go try them and see which you prefer. There are minor differences between the Cardiology STC and the Master Cardiology. If you are doing a lot of Peds, stick with the STC, as the Master has Peds adapters. If you are just doing general medicine and don’t need the precision of the STC, you can save a couple hundred by getting the Cardio III. It’s getting almost like buying shoes, you need to go try them on and see. If you will be auscultation of heart sounds and need to hear grade 1 murmurs, you will want the STC.
