Description Rechargeable Fingertip Pulse Oximeter Medical-grade, rechargeable fingertip pulse oximeter for accurate oxygen saturation and heart rate monitoring. Small, lightweight, and easy to carry—perfect for freedivers, athletes, and anyone who wants reliable real-time health tracking. 3 Vital Reasons Why You Should Use an Oximeter: 1. You can PERSONALIZE your TRAINING Stop following generic, boring training programs. With an oximeter, you can measure your blood oxygen saturation during dry training, allowing you to adjust the intensity of your workouts based on your body’s adaptation. 2. Perform the VERY EFFECTIVE Interval Hypoxic Training (IHT) Method Boost your hypoxia resistance using the proven IHT method developed by elite freediver Eric Fattah—a technique that requires an oximeter to execute properly. 3. Get MAXIMUM RESULT on Static Apnea Training WITHOUT OVERTRAINING Avoid having a hypoxic seizure (blackout) or samba when knowing the lowest possible oxygen level you can withstand (only for high-level elite competitive freedivers). As your tolerance to hypoxia improves, this critical oxygen level keeps decreasing.
