The Graham Field Panascope series offers a lightweight and economical solution for high-quality auscultation. These stethoscopes feature an aluminum dual-head chestpiece with a chrome-plated rotating stem for seamless switching between the bell and diaphragm. The 500 and 500GY models are equipped with adult-sized chestpieces, while the 510 and 510GY are specifically sized for pediatric use to ensure better contact and acoustic clarity on smaller patients. All variants include color-coordinated non-chill rings for patient comfort, adjustable chrome-plated brass binaurals with an internal spring, and 22-inch latex-free tubing. Every set comes complete with an additional diaphragm and spare ear tips.
