3M Littmann Master Cardiology Stethoscope, Purple Tube, 27 inch 2167, 1 Ct

The Master Cardiology exceeded expectations when I used my first one more than twenty-five years ago. Working as a trauma surgeon and an ERP in both civilian and tactical environments I have been impressed with the ability to discern subtle auscultatory findings within a loud ambient noise environment. The craftsmanship and durability of the Littmann, in my opinion, are without parallel. The Master series remains high on my list of recommended equipment. Thanks for an outstanding product.
