Tom. Tom Spark 3 Design. We wont dwell too much on what the Spark 3 looks like because theres not a lot to report if youre familiar with the first Spark. It still has the same removable watch module and screen with the optical heart rate sensor built into the back. That does mean you can slip it easily into any other Spark straps you already own. It also uses the same charger, which were not the greatest fans off, but its not going to budge from that cradle when you need to power it up. Now use it better Tom. Tom Spark 3 tips and tricks. Tom. Tom has changed the strap though. The look is the same with a few colours thrown into the mix, but now the inner side of the strap is softer and more textured to help wick away sweat. If youre planning to wear it 2. Having worn the Spark all day, we know that it can get quite sticky underneath the strap and theres been a noticeable difference on that front. Youll also get a less of a strap imprint on your wrist as well. The strap design tweak along with a few more colours to choose from still makes this every bit a sports watch, but it certainly feels a lot more svelte than what you can get from Garmin or Polar. It doesnt try to masquerade as something more stylish, and thats fine with us. For now. Its light, comfortable, still has a really intuitive user interface and is very easy to use. Tom. Tom Spark 3 Sports tracking. I Lost My Drivers License Now What. As far as tracking is concerned, its more of the same. There are seven sports modes along with a stopwatch option offering the very same metrics as its predecessor. Theres also activity and sleep tracking although it still feels very secondary to the whole experience and very easy to ignore. Press left on the big physical button and you can see a daily or weekly breakdown of steps, calories, distance covered and active minutes. Data is in the same ballpark as the Jawbone UP3 weve worn alongside it for the past few weeks. But as weve said, it still feels very much of an afterthought. GPS tracking compared Tom. Tom My. Sport v Runkeeper. In terms of sports tracking, we focused our attention on outdoor running, but also put treadmill running, swimming and gym modes through their paces as well. For running, its still a fantastic performer. From the training modes to the quick GPS signal pick up, it still impresses. That GPS pick up on average takes about a minute to a minute and half on average, and while its not as rapid as most Garmin running watches, it was quicker than the Polar V8. Read this Best GPS watches for cycling ranked and rated. Crucially, its still just very easy to set up and get out running. If theres one slight niggle we still have, its that inability to view a workout summary without having to jump into tracking mode again. Its worse still if the battery is low and youre only using it in watch mode and cant check in on your last run. There are notable improvements for treadmill run tracking, something that wasnt all that great on the first Spark. Its still accelerometer based but on the few runs we put it to the test, its a lot more consistent with tracking distance covered on the treadmill. It makes a great swimming companion too, once you correctly configure the pool size. The original Spark won silver in our big swim tracking test, and its more of the same from the Spark 3. Tom. Tom Spark 3 Route exploration. The main reason youd consider upgrading from the Spark to the Spark 3 is the new route exploration feature. This basically means you can now go out on a big run and the route will be mapped out on the watch screen, helping you navigate your way home a little easier. You can now add routes to the watch as well, which is handy if you want to run an approximate distance or just freshen up your running routes. Its a feature that usually crops up on more expensive sports watches, so its definitely a positive to see it appear on the Spark 3. The reason you can do this on the Spark 3 is because Tom. Tom has now included a compass, which means unfortunately youre not going to see this feature crop up on the older Spark. If you just want to get out running and view your route, youll need to calibrate the compass first, which is done in the sensors section inside the watch settings. It requires rotating the module in different directions, and wed suggest taking the module out of the strap to do this as it didnt calibrate when we left it in. Then you can start tracking a run as normal and youll now be able to skip to a screen where you can an overview screen and a zoomed in screen to view your route. After a few runs and doing my best to get lost, it did get me back to my starting point. The more interesting application is the ability to upload routes. Tom. Tom supports the ability to upload GPX files, the most common GPS data file format. To get one uploaded to the Spark 3, a quick Google search will quickly find you what you need, but a good place to start is Map. My. Run. Here you can easily create routes or search routes and download them to your computer. Then youll need to upload them through the Tom. Tom My. Sport web app. Its a pretty painless process and then youre good to go exploring. When you start to track a run, you can now select a trail. Its as easy as that and its worked perfectly fine for us on the few runs weve tried it with. According to Tom. Tom, youre not required to calibrate the compass before activity but the Spark 3 will offer to calibrate if it considers its needed. You can still calibrate whenever you wish as well. Will it be enough to convince Spark owners to upgrade That really depends on how much you value the option to mix up your running routes. We certainly enjoyed having it and itd definitely come in handy taking the watch abroad or into unknown territory. We think its a great addition, and it works well. Tom. Tom Spark 3 Heart rate training. Optical heart rate sensors get a rough ride especially from us and we think rightfully so. Weve seen a handful of devices that provide accurate date. An exception to that rule was the Tom. Tom Spark. Since the company moved from using the same technology used in the Mio Alpha 2 and Fuse, its proved to us that optical heart rate tracking can be good. Heart rate tracking compared Tom. Tom My. Sport v Polar H7 Thankfully its more of the same with the Spark 3. Heart rate data is recorded as youre tracking but you can also take part in heart rate zone based training, letting you work in Sprint, Speed, Endure, Fat Burn, Easy or Custom zones. Its a nice addition to the overall setup, but crucially, accuracy is still great. We put it up against a Polar H7 heart rate monitor chest strap for several runs and the sample below of the data compared to the H7 paired with Runkeeper shows its still a reliable monitor. Mixing things up with some high intensity training yields similarly good results. The Spark 3, like the original Spark, houses one of the best optical heart rate monitors weve tested. Its not 1. 00 perfect.
