Sprague Rappaport type training stethoscope with double binaurals and tubing for teachers and students. Perfect for anyone who wants to be able to hear the little details of auscultation at exactly the same time as their student/teacher. Dual function chestpiece works well with both children and adults due to its large and small diaphragms situated on each side of the chestpiece. Only one side of the chestpiece works at a given time, reducing outside noise from the side not being used. Simply twist the base of the chestpiece to the desired position to access either the large or small diaphragm.
