The Polar H7 Heart Rate Sensor is one of the best and most accurate HRMs for sports and fitness you can buy.

Accurate; Soft and flexible; Easily adjustable; Compatible with both fitness devices and smartphones; Good price; Machine washable strap; Uses Bluetooth

Slightly bulky sensor; Only works with a few mobile apps

Blutooth HR strap linked to my iPhone without problems and now can use it with apps like Stava to add HR data when training

The current trend may be to move heart-rate monitoring away from the chest and over to the wrist but accuracy at these new locations is still questionable. The Polar H7 heart-rate monitor takes the traditional chest strap and adds Bluetooth Smart support giving you heart rate data on sports watches,...

Light and comfortable; Accurate readings; Works with smartphones and third party apps; Great companion app

Slightly difficult to unscrew back to access battery

Love it! Paired easily with my lezyne bike computer and I use it all the time in the gym and use the Polar app along side it. Easily pairs with gym equipment

I was looking for a heart rate monitor that worked with my erg/rowing machine. I didn't want to have to wear a watch. The heart rate monitor works with an app on my smart phone or the machine. The strap is comfortable and I have no complaints. Does exactly what I need.

Good Value

What can you say It's a solid Polar heart rate monitor that is pretty accurate if not spot on. Needed this older model to connect with my Northern Lights ARC-102 rower over Gymlink, which can be used at the same time as Bluetooth to my phone. Better price than in local stores.
