The Harvey™ DLX Stethoscope is specifically designed to accentuate important sounds and enable you to hear cardiac, pulmonary, and vascular sounds without relying on difficult variable-pressure techniques. The Harvey DLX is equipped with dual-bore tubing that creates two uninterrupted sound channels and works with the optimally weighted chrome-plated brass chestpieces to transmit a full range of physical sounds. Providing clear, crisp sound, the Harvey DLX helps enhance your auscultation capabilities.
