2025 United States Guide: Top 5 Real-Time Telemetry Equine Heart Rate Monitoring Systems — Expert Review for Vets & Trainers (Polar Equine H10, EQUIMETRE Arioneo, Hylofit, Nightwatch, Estride)

The Polar Equine H10 is a widely adopted, general-purpose chest-strap heart rate sensor known for clinical-grade accuracy, broad Bluetooth/ANT+ compatibility and a mature software ecosystem, making it a cost-effective choice for real-time telemetry in equine settings. Compared with more equine-specific systems on this list, Polar’s financial advantage is lower entry cost and no vendor lock-in — it trades specialized horse mounting and bespoke analytics for proven interoperability and large-scale reliability. For teams that prioritize budget-friendly, easily integrated telemetry over niche features, the H10 often delivers the best value per sensor deployed.

The EQUIMETRE Arioneo system is built specifically for horses and stands out for combining high-resolution cardiac telemetry with gait, GPS and workload analytics, offering trainers actionable, sport-specific metrics in real time. Technically it surpasses general heart-rate-only sensors by fusing multiple biosignals and rider-facing dashboards, although that specialization typically comes with higher device and subscription costs compared with commodity sensors like Polar. For stables seeking rich, equine-centered insights (and willing to pay for them), Arioneo is positioned as the performance-analytics market leader.

Hylofit targets continuous, everyday cardiovascular monitoring with an emphasis on endurance and veterinary use, delivering long-term trend telemetry and automated alerts suitable for both training and health surveillance. Financially and operationally it occupies a middle ground: more equine-tailored than generic chest straps but generally less expensive and simpler than full performance telemetry platforms, making it attractive to riders who want persistent monitoring without enterprise-level cost. Its strength is in continuous remote monitoring and cloud-based trend analysis rather than the in-depth multi-sensor training dashboards of some competitors.

The Nightwatch Smart Halter is engineered around overnight and clinical cardiac monitoring, offering high-sensitivity detection of arrhythmias and respiratory events through an easy-to-fit halter and automated alerting — a clinical-grade complement to performance systems. Compared to race-focused telemetry devices, Nightwatch emphasizes medical detection and early-warning functionality, which can justify higher per-unit cost for owners prioritizing health surveillance over training metrics. Where real-time racing telemetry providers focus on latency and multi-horse broadcasts, Nightwatch differentiates on diagnostic specificity and continuous health safety.
