First of all, during the course of the day it counts how many steps you've taken using it's built in pedometer, it also measures your heart rate, calories burnt and how many flights of stairs you've walked up. All of this adds up to a substantial amount that you can use together with a workout which can then be uploaded to the Discovery Health website where you can earn up to 150 points / day.
Secondly, when you do a workout e.g. a run, it will not only track your route (using it's built in GPRS) but it will also give you a summary of the run itself:
Once synced via Bluetooth to your smartphone and using the Fitbit App, it'll then show you the map of your route as well as the KM splits.
Oh, and in case you run with your iPhone because you like listening to music, you can use your Surge as the control. It will also in turn show you who's calling or who's just sent you a text message. Nifty, hey?
Also, just like the Charge HR, wearing the Surge at night will allow it to track your sleep so that when you wake up in the morning and download the data to your phone, you can see how well you slept. Am still unsure of what to make of this info though...
I can't actually think of one thing I don't like about the Surge. Even the price isn't that bad at around R4,000 and they come in a variety of colours.
There is, however, one small pain - charging. Look, you can do it overnight every week or so, so it's not bad. Stop Whining!
It's been ages since I've worn a watch that I truly have enjoyed wearing. Am wondering what's next on the Fitbit agenda...
