Review: 凄く安定して使えてます 手首の計測とは雲泥の差です ポラールペーサーと同期して 使っています。

## Features

- Designed for High Accuracy: The COROS optical heart rate sensor provides a heart rate that rivals the heart rate sensor in the chest It breaks the limits of wrist measurement and provides accurate data for about 38 hours continuously for all activities such as cycling, running, climbing, high-intensity interval training, etc
- (Why Arms? While the heart rate sensor that wraps around the wrist is convenient, there are still challenges with accuracy across all brands and products However, the upper arm has the optimal blood flow, and by attaching the heart rate sensor to the arm, more reliable data can be obtained
- 【Comfort that lasts】The chest heart rate sensor is highly accurate, but the wearing comfort is not quite there The COROS heart rate sensor uses soft fabric and a thin band to prevent snagging Therefore, it can be comfortably worn securely on the wrist The buckle is adjustable for a secure fit on the skin Also, the Velcro closure makes it easy to remove when washing
- 【No buttons, no frustration】The COROS heart rate sensor features automatic wear detection, which automatically turns the power on/off based on the wear status Can be connected simultaneously with other sports watches or Bluetooth-enabled devices (e.g., indoor trainers, cycle computers, etc.) Note: The heart rate sensor alone cannot be connected to the COROS app for measurements Must be used in conjunction with the watch The COROS heart rate sensor only supports Bluetooth connection (NOT ANT+ compatible )
- 【Excellent Band】The high-precision measurement function is activated by securely fixing the optical heart rate sensor to the skin COROS bands are designed with sensors that fit snugly against the arm to prevent external light from entering

ランニングで使用。胸バンドは使いづらく、手元のスマートウォッチだと心拍の追随が不安定なため購入。しっかりと表示されるし安定している。バッテリーも長持ちするので良くできていると思います。

### ⭐⭐⭐⭐⭐ Review
*by A***ー on January 3, 2026*

これまで手首のスマートウォッチで心拍数を測定をしていましたが、精度に対して疑うようなケースがあり、トレーニングが正しく負荷がかかっているのか疑うことがありました。 いつもと違う心拍数が測定されると本当にいつもと違う状態なのか、誤検知による異常値なのか疑い、トレーニングに集中できていませんでした。 今回アームバンド型のセンサーを購入したこで、測定精度に対する安心感があり、トレーニングに集中することができるようになりました。購入して本当に良かったです。 スマートウォッチは別ブランドのものであっても接続できるため、わざわざスマートウォッチを購入し直す必要が無かったというのも、とても良い点でした。 これがあれば今後も精度の高いモデルが新たに発売されたとしても、そこまで必要ないかなと感じてます。
