Garmin’s latest flagship – the Forerunner is not geared for the average fitness enthusiasts, unless of course you can’t take any chances with your fitness results. Add to this, if you’re looking for a fitness tracking wearable that literally comes with all the bells and whistles, the Garmin Forerunner 630 is inarguably a solid choice. A successor to the Forerunner 620, the Forerunner 630 brings to the table a whole new round of features, most notably a few design tweaks to enhance its aesthetic appeal and phone notifications.
Unlike other fitness wearables that offer sleep tracking and running metrics only, the Garmin Forerunner pushes the envelope with the addition of GPS. The only pitfall of the Forerunner 630 is it doesn’t come with an onsite heart rate monitor, but Garmin’s addresses this issue quite well by providing a bundle package as well that includes a class leading HRM-Run monitor. With a lack of an onsite heart rate monitor, Garmin hasn’t skimped out in any way, but instead has justified that the Forerunner 630 renders near absolute accuracy in heart rate tracking.
Although a chest strap and wrist based optical heart rate sensor use the same technologies and algorithms, the difference in accuracy results from the fact that the latter reads your blood flow further from the source so its accuracy can be compromised by the light leaking and affecting the sensor. Contrariwise, chest heart rate straps just like the name suggests are located and track closer to the heart hence they tend to render a more accurate reading.
