The ProCardial Core Titanium - an unprecedented first for light-weight cardiology stethoscopes. The convertible adult and pediatric stethoscope is handcrafted in premium grade titanium, popularly used in medical implants and aerospace due to its super strength, durability, and ultra-low weight. Truly an innovation for the on-the-go clinician, the ultra-light ProCardial Core provides flexibility in assessment, quickly converting to an adult or pediatric stethoscope with its screw-on convertible chestpiece. At nearly half the weight of stainless steel, you can accurately auscultate heart, lung, and korotkoff sounds for both adult and pediatric patients.
