There's good reason for that label. The final version I tested has built-in GPS, a heart-rate monitor and real-time workout data, all fan-requested capabilities that raise the price.
Yes, its specs make it the most powerful Fitbit yet, but is it ahead of this stepped-up competition or gym class-awkward among its brawnier peers? Time to put it through my paces.
Design and display
Designed for workout performance, the Fitbit Surge fastens a noticeably larger LCD display to your wrist, and it's able to easily cycle through multiple stats. Gone is the single-line OLED.
This backlit, always-on interface allows you to keep tabs on your steps, miles, active minutes and heart rate on a black-and-white, 1.25-inch screen.
Fitbit Surge upgrades to a touchscreen, and puts three physical buttons at your fingertips. It's just more control to set everything from workout timers to GPS tracking to music controls.
The display is not in color and doesn't fit as much information on one screen like the Garmin Forerunner 920XT, but now there's no need to cycle through by pressing a single, tiny button.
I do wish that the Fitbit Surge included an option to cycle back to the current time after a while – and came with additional faces besides the four preinstalled watch faces to make the watch portion more relevant. An update could easily fix these oversights.
Tucked underneath the watch band is an optical heart-rate monitor and at ends of the straps is a strong wristwatch clasp that is easier to fasten than Fitbit's usual two-pronged approach.
I nearly lost my Fitbit Force in a parking garage before driving 30 minutes away and then 30 minutes back to fetch it – all because of that previous ill-conceived design.
The new watch clasp is two Fitbit-sized steps in the right direction. It's also available on the Fitbit Charge HR, but not the Fitbit Charge, so avoid that version if you tend to lose things.
While the Fitbit Surge functionality is more advanced, the square look and bigger size is akin to a dated, '80s digital watch. It's not fashionable, yet stands out more than previous Fitbits. It doesn't help that it comes in only black, with blue and tangerine "coming soon."
At its thickest point, the watch case is half an inch thick off the wrist and its strap is an inch wide. That's about 1.5 times wider than the Fitbit Charge HR band and tough to hide.
The large, rubber-coated lugs at the top and bottom of the Fitbit Surge make tucking it into a shirt sleeve an extra workout Fitbit failed to advertise.
Fitbit Surge now has a total of eight sensors crammed into its large frame, which, along with the LCD touchscreen, accounts for its expanded size.
This means it can track all sort of movements beyond a fitness gadgets' routine metrics of steps, distance traveled and calories burned.
An altimeter, for example, is here to monitor how many floors you've climb in a day. That's a stat that's not available in all Fitbits, including the popular Fitbit Flex.
GPS is a completely new sensor to the Fitbit family. It can map your runs using Google Maps while generating step-by-step graphs for elevation, pace, heart rate and calories burned.
The best part is that Fitbit Surge's satellite tracking works without your phone. You can leave that at home, a feature that's not available in the new Apple Watch.
There's something motiativing about reviewing your entire run laid out on a familiar overhead map and trying to best it the next time. You know you need to push it at certain landmarks.
Fitbit Surge's GPS tracking isn't the most accurate I've tested, with noticeable smoothing around corners and, at times, off-track routes that are a street and a half over.
All is not lost, however, as these GPS errors are few and far between. More often, I found Fitbit's always-inflated step counts to push me to my 1,000 steps goal faster than expected.
My higher-than-normal step count did stay consistent. That made day-to-day goal-beating just as important and at least kept me consistent with my friends and family wearing older Fitbits.
Run tracking, without or without GPS, can be initiated right from the watch, so there's no need to go to the app screen or press a secret pattern of buttons to get started.
The full list of exercise shortcuts are weights, elliptical, spinning, yoga, workout, stair climber, circuit training, bootcamp, kickboxing, tennis golf, walking and, yes, even martial arts.
A post-launch Fitbit Surge firmware update has been announced in order to bring bike tracking to that list. The new software will also bring Multi-Tracker Support so you can wear as many Fitbits as you want.
Needless to say, I never felt robbed of fitness tracking modes with the Fitbit Surge. The app also has a menu for food planning, but it remain cumbersome to track and is worthless.
All of the collected data syncs to the Fitbit app as well as an easier-to-study web interface, a bonus that the mobile-only Jawbone Up products don't offer.
