The Hammerhead 2.0 heart rate monitor is one of the most lightweight heart rate monitors on the market, providing you with real time heart rate data on your exercise machine. Its patented honeycomb pattern maximises the skin contact area and improves moisture wicking, which minimises the chance of the heart rate band sliding around.
Accurate
The heart rate monitor can easily be fitted around your chest using a strap. The monitor measures the electrical activity of your heartbeat, which results in an accurate heart rate measurement. The Hammerhead heart rate monitor is equipped with a conductive rubber material, which is highly sensitive and capable of measuring your heartbeat in all circumstances. This material is resistant against ageing, temperatures and moisture.
Waterproof
With the waterproof Hammerhead heart rate band, you won't have to worry about sweat or water interfering with your sensor. You can remove the sensor in order to wash the heart rate band.
R-R variability
One of the improvements compared to its predecessor is the ability to track the intervals between heartbeats. That means this heart rate monitor will also provide you with information about your heart rate variability (HRV) while you're exercising!
ANT+
You can use ANT+ connectivity to pair this device with other devices which support ANT+, so you can connect devices from different manufacturers without any problems. Many bike computers and compatible sensors come equipped with this wireless technology. This means all your sensors and devices can easily share data with one another. You'll have all your data in the right place.
Dual Bluetooth
Easily pair this device with most smartphones using Bluetooth connectivity. In this way, you can get insights into your training data in all your favourite fitness apps, including Strava, Runkeeper, Endomondo or Wahoo Fitness. You can even connect your heart rate monitor to two devices at the same time using Dual Bluetooth.

Cheap but does not work properly
- Simon 5 January 2026
The Hrm is really not working properly. It does not connect automatically and it only seems to work if I reset it, i.e. by disassembling it and putting the battery back in. This is also all pretty loose and definitely not sturdy.
Pros & Cons
Battery is fairly loose in the device
Does not connect automatically. Must reset every time
