Top 5 Digital Stethoscopes for Equine Health in the USA 2025 — Expert-Reviewed Guide to 3M Littmann CORE, Eko DUO, Thinklabs One, eKuore Pro, and HD Medical ViScope MD

The 3M Littmann CORE holds a market-leader position for equine auscultation because it combines trusted Littmann acoustic engineering with digital amplification and recording, delivering clear cardiopulmonary sounds even on large-thorax patients. Compared with smaller specialist devices on this list it provides a more mature accessory ecosystem, broad clinician adoption and stronger resale value, though it is generally priced higher than budget models such as the HD Medical ViScope. For first-aid and field use its proven durability and reliable Bluetooth recording make it a go-to option when clinical-grade fidelity and long-term support matter most.

The Eko DUO stands out for equine health because it uniquely combines a digital stethoscope with single-lead ECG capability, enabling frontline detection of arrhythmias and providing complementary data that purely acoustic devices lack. While it is typically more expensive than single-function stethoscopes like the Thinklabs One or HD Medical ViScope, the added ECG data can materially improve triage and treatment decisions in the field. Compared with Littmann CORE it trades some brand longevity for multifunction diagnostic power, making it especially valuable for ambulatory vets and first-aid responders who need both heart sounds and rhythm information.

Thinklabs One is prized in equine first-aid scenarios for its extremely compact form factor and very high amplification and broad frequency response, which helps reveal subtle pulmonary and cardiac clues in noisy outdoor settings. It is typically more affordable than premium hybrid units and excels when portability and raw acoustic detail matter, though it lacks integrated ECG and the larger accessory network of brands like Littmann or eKuore. For practitioners who prioritize field mobility and maximum sound gain over bundled telemedicine features, the Thinklabs One is a top technical choice.

eKuore Pro occupies a strong position for equine use by offering tunable acoustic/digital modes, reliable Bluetooth streaming and a range of veterinary-compatible chestpiece options at a competitive price point. It balances veterinary-focused accessories and telemedicine-friendly software better than many generalist devices, making it cost-effective for clinics that need multi-user connectivity without paying flagship premiums. Compared with the Eko DUO it lacks integrated ECG but often undercuts Littmann on price while delivering specialized options that suit ambulatory equine practice.
