Unique design that combines the acoustic response of a traditional bell and diaphragm into a convenient one-sided chestpiece. Bell-type low frequency response is achieved by simply holding the chestpiece in place with light pressure. Firm pressure will produce diaphragm-type high frequency performance. A rubber gasket recessed into the chestpiece alters the diaphragm permitting the scope to achieve multi-frequency response. Chestpiece made from lightweight zinc alloy plated with an attractive satin finish. Non-chill diaphragm retaining rim for patient comfort. Lightweight aluminum binaurals with matching satin finish. Double leaf internal spring fixed at 15 angle for greater comfort. Reinforcing yoke molded into flexible 22" PVC Y tubing. ADSOFT- Child Adscope-Lite, Black
