There's no denying the H10 offers superior features over the H7 for anyone looking to get into shape. It's almost a complete update and it only costs $40 more. Still, if you're new to heart rate sensors for your chest, there's nothing wrong with selecting the older model. Your wallet might thank you.

Unfair comparison

In the H10, Polar has brought chest-based heart rate sensors to a new level. As such, on numerous points, it's a step up from the older model.

Do you already own the H7 but are looking to upgrade? The H10's new pod and strap are interchangeable with the previous strap and pod.

In doing so, the strap handles sweat much better and also attaches to the body better.

Both the H7 and H10 connect to smartphones using Bluetooth SMART, so there's no difference here, although you'll have to confirm whether the H10 works with your smartwatch — it might not work with older ones.

By contrast, the H7 can't be updated and the

Despite these upgrades, the H7 still packs a punch and on the more significant points, does the same things as the newer model. This includes third-party app integration, 5kHz transmission of data, and more. Plus, it costs $40 less than the H10 and it still lasts 200 hours between charges. The bottom line: If you want to save some cash or aren't fully committed to this heart tracking thing, stick with the older product and spend less.
