Magene Chest Strap Heart Rate Monitor ANT+ Bluetooth

The Magene H603 is a split-design chest-strap heart rate monitor that delivers accurate, real-time heart-rate data to ANT+ and Bluetooth devices with long battery life and IP67 protection.

If you want a reliable chest strap that pairs with cycling trainers, fitness apps and gym equipment while resisting sweat and movement noise, the H603 is built for continuous tracking. It uses a proprietary algorithm to filter motion artifacts, offers simultaneous ANT+ and Bluetooth output, and includes a flashing LED for quick connection confirmation. The shell uses durable IML molding and comes in four colors to suit different training environments.

How precise is the heart-rate data during intense workouts?

Magene’s H603 employs a self-research algorithm designed to reduce interference from motion and sweat, producing cleaner data than a basic strap. The split strap design also improves contact stability during vigorous activity so readings remain steady. You’ll still want to ensure snug placement on the chest for best results.

• Real-time heart rate extraction with motion-noise filtering
• Split chest strap for improved contact and comfort
• LED indicator confirms sensor activation and pairing status
• Compatible with trainers and gym machines for consistent input

Which devices and apps can the H603 pair with?

The H603 broadcasts over both ANT+ and Bluetooth, allowing simultaneous connections to two receivers or apps. ANT+ compatibility covers popular bike computers and cycle trainers, while Bluetooth works with phones and many training apps. This makes it easy to record the session on multiple platforms at once.

• ANT+: Magene, Wahoo, IGPSPORT, Bryton, Black Bird
• Bluetooth: Zwift, Strava, Wahoo Fitness, TrainerRoad and more
• Works with fitness machines like Peloton and Concept2 for studio use
• Can stream to phone apps and bike computers concurrently

How durable is the strap and what’s the battery life?

The sensor housing uses IML injection molding to resist wear and prevent fading in sweaty environments, and the unit meets IP67 for dust and water protection. A single battery supports up to an estimated 1,000 hours under laboratory conditions, giving long service between battery changes. The unit includes a one-year warranty against manufacturing defects.

• IML shell: scratch- and fade-resistant for long-term use
• IP67 rating for water and dust resistance during workouts
• Estimated 1,000 hours battery life (lab-tested; varies with use)
• 1-year warranty (excludes man-made damage)

How easy is it to use and check connection status?

Once the sensor is fitted correctly on the chest, the H603’s LED flashes automatically to indicate it’s active and ready to pair. The red LED confirms the monitor is operational; it flashes a set number of times after a proper fit. Pairing is straightforward through ANT+ devices or Bluetooth-enabled apps, and simultaneous output lets you log data on more than one platform.

• Automatic LED activation on correct placement
• Red flashing light confirms ready-to-use status
• Simple pairing with ANT+ and Bluetooth receivers/apps
• Split strap design makes fitting quick and secure

Who is this for: The Magene H603 is aimed at cyclists, triathletes, indoor-trainer users and gym-goers who need dependable chest-based heart rate data across multiple devices and apps. It’s also suitable for anyone who prefers a strap sensor for accuracy over wrist-based monitors, who trains in sweaty conditions, or who wants simultaneous ANT+ and Bluetooth streams to record and analyze workouts.
