The 3M Littmann Lightweight II S.E. Stethoscope is an ideal entry-level instrument, with a tunable diaphragm, dual-sided chestpiece, and reliable acoustic performance. Its teardrop shape makes auscultation around blood pressure cuffs easier. The colors shown online are approximations. We have made every effort to show the best possible match to the color of the actual product. However, some variation is expected, due to differences in both lighting and monitor calibration.
