The MDF® ProCardial ERA™ is the very first stethoscope of its kind. We promise, you’ve never seen a stethoscope like this. It is a stethoscope completely reinvented and you won’t believe how light it is. In addition to the redesigned lightweight headset and patented sound-sealing A2X tubing, it features a convertible chestpiece with 3 real bells and 3 separate diaphragms in adult, pediatric, and infant modes. Enhanced by 10 unique patents, the precisely handcrafted ProCardial ERA™ abolishes the age-old dichotomy by proving a true high-performance stethoscope can also be lightweight. The ProCardial ERA™—a true paradigm shift.
