The STC cardiology stethoscope and the matrix are both large cardiology. It takes some practice to apply the pressure drop at the head of a frequency change, but these are both great. I have had for many years a cardiology III. They are sturdy old horses in work. You can 't go wrong with either one of the new designs if you can afford. Most places that sell them will leave the test before they determine them to buy. You should go try them and see which you prefer. There are minor differences between the STC and cardiology cardiology matrix. If you are doing a lot peds, stick with the STC, as the Lord has adapters peds. If you're just doing general medicine and don 't need the precision of STC, you can save one hundred a couple getting the cardio III. It 's that gets almost like buying shoes, you have to go try them on and see. If you are the auscultation of heart sounds and need to hear the grade 1 murmurs, like the STC.
