The dual-frequency, "tunable" diaphragm allows the user to listen to both low and high frequency sounds by simply altering pressure on the chestpiece. Firm pressure allows the user to hear high frequency sounds. Ease off to light "skin contact" and the diaphragm lets you hear low frequency sounds (previously heard using the traditional bell). Choose from black, grey, navy blue, hunter green, burgundy or caribbean blue.
