The CAROL H3 Heart Rate Armband

Discover CAROL's Heart Rate Armband, offering reliable heart rate measurement and comfort for your REHIT workouts.

At CAROL Bike, we understand the importance of reliable heart rate monitoring for achieving the best results from your workouts. That’s why we’re excited to announce the launch of our latest accessory, the CAROL H3 Heart Rate Armband. 

Why a heart rate armband?

When you purchase a CAROL Bike, you will receive a complimentary CAROL H1 Chest Belt Heart Rate Monitor, the gold standard for accurate heart rate measurement. However, we recognize that chest belts may not be ideal for everyone. For some users, particularly those with dry skin or significant body hair, establishing a good connection between the skin and the chest belt electrodes can be challenging. Additionally, some women might find placing the chest belt inconvenient, especially when wearing a bra. In gyms or public spaces, lifting one’s shirt to put on a chest belt can feel awkward and intrusive.

 

In these circumstances, a heart rate armband with an optical sensor can provide a convenient alternative. However, after testing every available heart rate armband on the market, we found that none were accurate or responsive enough for our unique Reduced Exertion HIIT (REHIT) rides. The rapid heart rate increases during sprints were often missed, leaving the monitors “lost” for extended periods. 

Introducing the CAROL H3 Heart Rate Armband

We are proud to present the CAROL H3 Heart Rate Armband, which for the first time, offers the accuracy and responsiveness required for REHIT rides. This new accessory addresses the inconveniences of a chest belt, ensuring comfortability alongside reliable heart rate data. 

Key Features of the CAROL H3 Heart Rate Armband

High-quality optical sensor

 

The CAROL H3 Armband features the highest-quality optical sensor. This ensures that your heart rate is measured accurately, even during the most intense workouts. 

 

Reliability during maximum intensity sprints

 

The CAROL H3 Armband runs its optical sensor at maximum intensity, ensuring reliable measurements during REHIT sprints. 

 

Highly responsive algorithm

 

 The CAROL H3 Armband deploys a responsive algorithm with less data averaging than is common in other armbands. This means that it can more quickly detect and respond to rapid changes in your heart rate, providing you with meaningful feedback during your rides. 

 

Personalized heart rate zone indication

 

When used with your CAROL Bike, the armband will indicate your personalized heart rate zone through a colored LED signal. 

Battery Life Trade-off

One important trade-off with the CAROL H3 Armband is battery life. While many competitors prioritize battery life over accuracy and responsiveness, often offering up to 40 hours of continuous use, the CAROL H3 focuses on delivering the most precise data possible. As a result, its rechargeable battery allows for 11 hours of continuous use before needing to be recharged. 

Pricing and Availability

The CAROL H3 Heart Rate Armband is now available for purchase at $139. Given its reliability, responsiveness, and convenience, it’s a valuable alternative to the CAROL H1 Chest Belt.
