AMG’s Premier Elite Dual Head Stethoscopes provide health practitioners the flexibility to quickly switch from diaphragm to bell in order to clearly distinguish high and low frequencies. The fine tuning of the bell side can be used for detecting auscultation of smaller or extremely thin patients, for examinations involving bruits and intercostal spaces, as well as for observing low frequency sounds. Applying firm pressure to the chestpiece allows you to monitor high frequency and deeper thoracic sounds.
