A stethoscope is a diagnostic instrument used by medical professionals used to hear sounds generated from a patients chest cavity, heart, and various pulse points. Stethoscopes are also used by nurses to listen for restored blood flow while measuring blood pressure.

• The patented tunable diaphragm allows you to listen selectively to low or high frequencies without having to turn over the chestpiece.
• For your comfort and control, the stethoscope chestpiece is finger-contoured for a secure hold and has a nonchill rim for the patients comfort.
• The eartubes are set at the proper anatomical angle so they don't need readjusting.
• The patented 3M Littmann Snap-tight Soft-sealing Eartips remain secure, yet may be easily removed for cleaning or replacement.
• A patented double-leaf binaural spring inside the tubing (unlike Sprague Rappaport-type scopes), maintains proper headset tension. You may adjust the headset tension simply by flexing the yoke.
• The single-lumen tubing makes the 3M Littmann Stethoscope very portable and less bulky than many double tube stethoscopes.
• Backed by a two-year warranty.

Tunable technology provides convenience, versatility and enhanced acoustics. Its dual-frequency diaphragm combines both bell (low-frequency) and diaphragm (high-frequency) modes in one chestpiece side. You control bell and diaphragm modes by pressure on the chestpiece rather than turning it over.

Bell Mode low-frequency) Light contact with chestpiece allows you to hear low-frequency sounds.

Diaphragm Mode (high-frequency) Without turning the chestpiece over, use firm pressure to hear high-frequency sounds.
