What is the advantage of a two-tube stethoscope?
Two-tube stethoscopes, such as the ADSCOPE 600, 601, 602 and 641 (the 600-602 feature our two tube in one design, while the 641 actually has two separate tubes) provide better stereo separation allowing you to hear the subtle characteristics of heart sounds and murmurs more distinctly. The heavier tubing also filters out the distracting noise typical of a busy medical environment.
