- 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.
