Key Features and Benefits

• Outstanding Acoustic Sensitivity: More than twice as loud as the next leading stethoscope, making it easier to detect low-frequency heart sounds (below 120 Hz) such as Korotkoff sounds, Mitral Stenosis, and S3 and S4 Gallops.
• Dual Tunable Diaphragms: Single-piece diaphragms on both adult and pediatric sides allow you to hear different frequency sounds by adjusting chestpiece pressure.
• Convertible Pediatric Side: Switch from a tunable diaphragm to an open bell by replacing it with the included non-chill bell sleeve.
• Dual-Lumen Tubing: Two sound paths in one tube eliminate the rubbing noise created by traditional double tubes, ensuring clearer auscultation.
• Durable Next-Generation Tubing: Resistant to skin oils, alcohol, and stains, while maintaining shape and flexibility in clinical use.
• Lightweight Design: Weighs less than comparable high-performance stethoscopes for reduced strain during extended use.
• Comfort-Focused Headset: Easily adjusted for a personalized fit, with angled eartubes that align naturally with the ear canals.
• Hygienic and Easy to Maintain: Removable single-piece diaphragms and non-chill rim enhance cleaning and patient comfort.
