Chest strap Core CORE 1 by Core — wireless heart rate monitor chest strap

The Core CORE 1 chest strap is a wearable wireless heart rate monitor designed to be worn around the chest for direct, continuous pulse measurement during exercise and daily activity. It transmits heart rate data in real time to compatible devices, enabling accurate monitoring for training sessions, fitness tracking and general health awareness. The strap is intended to deliver reliable heart rate readings with minimal motion artefacts and stable wireless connection during running, cycling and gym workouts.

Advantages

The chest-worn sensor provides direct ECG-based pulse detection for improved accuracy compared with wrist-based monitors. Wireless transmission ensures data is sent in real time to smartphones, sports watches or bike computers that support standard heart rate protocols. The strap is lightweight and adjustable to fit different body sizes, and its design emphasises skin contact stability to reduce signal loss during vigorous activity. Battery life and simple connectivity contribute to uninterrupted heart rate tracking during typical training sessions.

Suitable for

• Running and interval training where continuous heart rate monitoring is required
• Cycling and indoor trainer sessions that use external heart rate data
• Gym workouts including cardio and circuit training with heart rate zones
• Fitness tracking and health monitoring for accurate pulse records

Key specifications

• Form factor: chest-worn strap with detachable sensor pod
• Measurement: continuous heart rate (ECG-based sensing)
• Connectivity: wireless transmission to compatible devices using standard heart rate protocols
• Fit: adjustable elastic strap to accommodate various chest sizes
• Durability: water-resistant construction suitable for sweat and light exposure
• Power: replaceable or rechargeable battery with operation time appropriate for multiple training sessions

How to use

Place the strap around the chest so the sensor pod sits flat against the skin beneath the sternum. Adjust the elastic band for a snug but comfortable fit to ensure consistent skin contact. Activate the sensor according to the device instructions and pair it with your smartphone, sports watch or bike computer using the device’s heart rate sensor search. Start your training app or device to begin receiving live heart rate data; disconnect and remove the strap after cooling down, and follow care instructions for washing and storage.

Usage recommendations

For best results, dampen the electrode areas slightly before putting on the strap to improve signal quality. Ensure the strap is not overly tight and check device compatibility with standard heart rate profiles. Clean and dry the strap after use, and replace or recharge the battery as indicated to maintain reliable performance.
