Introduction To Fitbit Blaze and Fitbit Surge

Fitbit may not be the first brand that comes to mind when people think about smartwatch, but the company has strong consumer base for its sport-centric wearables including running watch and activity trackers.

The Blaze and Surge are among the brand’s advanced multi-sport watches featuring optical heart rate monitor, touchscreen, smartphone connectivity and auto exercise recognition. Currently sitting at the top of the range in Fitbit’s trackers lineup, Blaze and Surge also offer everyday-watch form factor rather than sport-inspired design.

Fitbit Blaze

Unlike most sport watches, Fitbit Blaze is not entirely cased in plastic. It has a stainless steel frame attached to the band; there are 5 colors available including Black, Black/Silver, Blue/Silver, Plum Silver, and Pink/Gold.

Built-In Optical Heart Rate Monitor

The frame on the Black version is PVD coated. There is built-in optical heart rate monitor for 24/7 monitoring, even when you are sleeping. The color LCD screen is small, but it is touch sensitive. It has accelerometer, gyroscope, altimeter, vibration motor, and ambient light sensor as well. Despite its multiple features, the watch can last for about 5 days before it needs a recharge.

FitStar

Intended mainly as an activity tracker, Fitbit Blaze actually does more than just counting steps and calories. One thing that makes the Blaze stand out from the crowd is the FitStar. Once activated, the screen displays simple workout regimen completed with step-by-step instruction and visual guidance.

There is an animation depicting the movements of a fitness trainer; the idea behind FitStar is that you can follow the guidance, do simple yet effective exercise, and see the results directly on your wrist.

Statistics For Other Exercise

Although the Blaze fall under Tracker category in Fitbit products line, this watch is capable of measuring statistics for other exercises as well, for examples running, biking, and weights.

However, to use GPS–based functions on the Blaze (such as distance and speed – Blaze does not have built-in GPS), you must rely on your smartphone GPS. In case you forget to switch modes, the watch can automatically recognize the current exercise and do the computing accordingly.

Because it has accelerometer, you can wear this during indoor running on a treadmill, too. The on-board optical heart rate monitor analyzes your pulse and generates calorie computation data even when you are not moving, thanks to PurePulse technology. It divides training intensity into three heart rate zones including:

– Fat Burn: this is a moderate intensity zone in which your heart beat indicates that your body converts fat into energy. You can enter the zone simply by walking for few minutes.

– Cardio: commonly active during running or elliptical training, the zone represents medium intensity exercise that increases muscle and cardio strength.

– Peak: during interval or endurance training, Fitbit Blaze will display Peak heart rate zone. It means you are doing intense exercise to improve performance.

Because calorie computation is based on heart rate, you can do stationary training (such as with elliptical exercise equipment or weight lifting) without losing measurement accuracy.

PurePulse helps you achieve fitness goal or weight loss target by providing information about the correlation between certain physical activities and the amount of calories you burn.

When used as an activity tracker, Fitbit Blaze has a good range of features to help you stay healthy every day. It measures steps, calories, distance, and inactivity time. To prevent you from being inactive, the watch sends reminder for you to take at least 250 steps every hour.

Thanks to the altimeter, it also measures the number of stairs you climb. With Auto Sleep Tracking, Blaze monitors your sleep to figure out the total time you spend in deep sleep and restlessness.

Another important feature is smartphone connectivity. If you pair the watch with a compatible smartphone, you can check alerts for texts, emails, incoming calls, and calendar alerts directly on your wrists. While the screen is small, the texts are readable under most lighting conditions. You can also control your smartphone’s music player using the watch.

Fitbit Surge

Unlike the Blaze, Fitbit Surge is not modular but it comes in three sizes: small, large, and extra large. In terms of functionality, both devices are basically the same. In fact, you can find almost all the features available from Blaze in Surge, except FitStar.

With Built-In GPS

As a multi-sport watch, Surge is better with built-in GPS and a battery life that lasts for about 7 days between recharge. Another big difference comes from the screen department as the Surge is equipped only with touchscreen monochrome LCD.

Without differences in FitStar, GPS and screen specification, Blaze and Surge have the same functions as activity tracker and running watch. Form factor is also different, with the Surge leans toward sport-inspired design while the Blaze tends to be casual/formal everyday wearable.
