The new ADC Adscope 658 Electronic Stethoscope offers the opportunity to hear sounds that may have been missed with even the most expensive traditional acoustic instrument. The contact activated microphone filters higher frequency background noises (which typically obscures auscultation) and then amplifies heart and lung sounds up to 18x. Improvements in this third generation model include a user-replaceable diaphragm and a rechargeable Li-ion battery for greater up-time - up to 400 exams on a single charge. Also, at 175 grams, it weighs less than most cardiology scopes. The 658 features: Amplifies sounds up to 18X (24dB) Noise-filtering contact microphone eliminates background interference Eight-step volume control with last-setting memory Cardiology headset with bilumen tubing and stainless-steel binaurals Multi-function button controls the frequency mode (bell or diaphragm) and the volume (eight levels) Backlit LCD display powers down automatically if not in use Rechargeable Li-ion battery, twenty hours of continuous use on a full charge High-impact thermoplastic housing withstands drops, bumps, and other contact Measures 30 inches and weighs 175 grams Contact microphone measures 7 mm in diameter, suitable for use on any size patient Includes three pairs of Adsoft Plus snap-on silicone eartips, two small and one large Micro USB cable and scope ID tag also included Two-year warranty on electronics (chestpiece), lifetime warranty on headset Total Weight: 6 oz Total Weight(gm): 175 g Scope Warranty: Electronics / Headset: 2 Year / Lifetime
