COROS Heart Rate Monitor review: A seamless band I didn’t know I needed

    Before I started carrying health watches, I ran with Runtastic or Strava and my cellphone’s GPS, which had no correct coronary heart fee information. I knew of chest coronary heart fee displays, however the discomfort and inconvenience — to not point out the excessive costs — made them unappealing. I solely want I’d had one thing just like the COROS Heart Rate Monitor throughout these years, as an alternative.Arm-based coronary heart fee displays fall between chest and wrist-based HRMs in accuracy however arguably win for consolation. It’s one thing you strap on and neglect about, particularly handy for gym-goers who do not desire a wristwatch interfering with workouts and weights. And even when you put on a watch, a strap provides you the understanding of correct information with out worrying a few completely tight, flat-on-wrist match. There are a couple of common arm-based straps already, just like the Polar Verity Sense or Wahoo TICKR Fit, however I’ve discovered the COROS HRM provides them a run for his or her cash, albeit with some limitations. I began utilizing the COROS Heart Rate Monitor on and off after its July launch, so I’ve had months to check it out. Its options are very specialised and arguably considerably restricted; I selected to attend on my evaluate to see the way it held up for accuracy, consolation, and battery throughout months of use. On each entrance, it greater than lived as much as my expectations and the take a look at of time. What else must be stated?Today’s finest Coros Heart Rate Monitor dealsHow the COROS Heart Rate Monitor works(Image credit score: Michael Hicks / Android Central)To arrange the COROS Heart Rate Monitor, you want the COROS app for iOS or Android. I already had it from my COROS PACE 3 evaluate, amongst others, however you may resent having to put in an app simply to arrange an adjunct — most different coronary heart fee monitor straps do not require this step. Non-COROS customers needn’t fear: as soon as it is arrange, you will by no means should open up the app once more until you need to.The strap connects over Bluetooth, which prompts the second that the built-in put on detection prompts. Simply slide it in your arm or maintain your finger over the photodetectors, and your machine ought to detect it. Take it off, and it goes dormant, so it will not by accident connect with your watch as you allow your own home to run. It pairs mechanically together with your COROS watch in case you have one; in any other case, you will merely must put your smartwatch, cellphone, app, health club gear, or biking machine in Bluetooth pairing mode, assuming it helps equipment. The message that pops up when beginning a Run exercise, as soon as the COROS HRM is synced to your watch. (Image credit score: Michael Hicks / Android Central)For instance, watch manufacturers like Garmin, Apple, and Amazfit work seamlessly with straps, whereas Fitbit does not, and Wear OS watches want Google Fit for them to work. For your cellphone, a couple of apps like Strava or MyFitnessPal allow you to join the strap immediately. Most train gear lately helps Bluetooth; you are solely out of luck if you have to connect with an ANT+ machine.Once linked, the COROS Heart Rate Monitor will keep in mind that machine, as much as three in whole. Compared to the Verity Sense (two remembered units) and TICKR FIT (just one), this can be a very nice perk! Plus, in my expertise, when you begin an exercise on a linked machine, the COROS HRM by no means takes greater than two seconds to sync.Swipe to scroll horizontallyCategoryCOROS Heart Rate MonitorMaterialsPolyester fiber, nylon, spandexSensors5 LED lights with 4 photodetectorsConnectivityBluetooth; Up to 3 units directly; connects as much as 120 toes from deviceBattery life55mAh: 38 hours (lively); 80 days (standby)ChargingProprietary USB-A; 2 hours to 100%Water resistance3 ATMWorking temperature-4°F to 122°F (-20°C to 50°C)Size & weight42.5 x 28.4 x 9.1mm; 19g / 0.67ozArm dimension fit7.09–12.6 inches (18–32cm)The headliner function of the COROS Heart Rate Monitor is its battery life. It lasts 38 hours per cost, with an 80-day standby mode. There’s no button to activate it, merely the wear and tear detection; as lengthy you are not carrying it, the COROS HRM will retain its juice for months at a time. Essentially, when you cost your COROS HRM after which throw it in a drawer for 2 months, you will discover it most likely has about 10 hours left if you discover it. Day by day, the drain is minimal. Its longevity is absurdly helpful. The COROS HRM battery standby mode means by no means having to show it “on” or “off,” understanding it has the battery life to final for dozens of exercises or months of idling. You can examine its battery life on the COROS app profile web page or else examine the LED indicator on the sensor’s aspect if you put it on. It’s usually inexperienced however switches to orange with 5% battery or much less. If it goes orange proper earlier than a exercise, don’t be concerned: it takes two hours to cost absolutely, however you possibly can add a couple of hours’ value of battery in minutes.The solely actual design “flaw” the COROS HRM has is its 3ATM water resistance. While you may assume meaning it may go 30 meters underwater, that actually implies that it is sweat, rain, and splashproof, however not meant to be submerged underwater. Unlike the Polar Verity Sense, you possibly can’t go swimming with this on. Comfort and accuracy(Image credit score: Michael Hicks / Android Central)At 19g, the COROS Heart Rate Monitor weighs lower than half as a lot as your typical health smartwatch, with a nylon strap that feels tender and clean in your pores and skin, together with spandex that offers it its stretchy high quality. The solely tough a part of carrying this strap is correct initially. You want to regulate its dimension in order that it stays securely in your arm with none sliding, however not so tight that it is uncomfortable or cuts off circulation. Once you have set it to the best dimension, although, it stays there, full cease. You’ll stretch it out so it settles on the best bicep top, after which you possibly can slide the precise sensor round so it sits on the outer portion. But when you let go, it will keep at the very same match as your final exercise. I have not seen any give or fraying develop over the course of months. The COROS HRM balances between consolation and a safe match very properly.My expertise with the COROS Heart Rate Monitor match is that it is at all times “noticeable” at first; it must be since you need it securely mounted. But as soon as I begin operating, my consciousness of it fades rapidly as I get into the zone, the identical approach you neglect you are carrying a smartwatch — solely extra so as a result of it is lighter and does not make your wrists really feel lopsided. By the time I sink right into a zone playlist over my new Shokz OpenFit earbuds, I not discover it.Unless you may have Arnold Schwarzenegger arms, the COROS HRM strap ought to match pretty simply. That stated, I’m undecided the way it’ll deal with workouts with precise bicep curling since I haven’t got a lot bicep muscle to talk of. That might make the strap really feel tight for sure health club conditions. You’d get the identical concern with a chest strap or wristwatch, simply with totally different workouts, so it is merely one thing to bear in mind. (Image credit score: Michael Hicks / Android Central)As for the COROS Heart Rate Monitor’s accuracy, I’ll crib from my very own Garmin Venu 3 evaluate, the place I in contrast the smartwatch’s revamped Elevate v5 sensor in opposition to the COROS sensor linked to the Forerunner 965. Essentially, the smartwatch did very properly at following the strap, however you possibly can see how the Venu 3 graph (gentle purple) lags barely behind the COROS HRM (purple), not at all times registering each rapid-fire change and tending to point out extra straight, averaged-out traces whereas COROS’ strap captured adjustments extra rapidly at once. Overall, the watch was just one bpm off from the strap, on common, throughout a 60-minute run. I assure that will not apply to loads of different watches, particularly finances fashions with fewer LEDs. For high-end smartwatches, although, the upside is extra restricted until you are a professional athlete who wants true precision information. Otherwise, the COROS Heart Rate Monitor provides you information that is extra correct than $400+ watches designed for health and at an $80 worth level. That’s nothing to sneeze at. I’ve solely proven one instance above, however all of my different COROS-based coronary heart fee graphs have held as much as scrutiny with no odd drop-offs or delays.Should you purchase the COROS Heart Rate Monitor?(Image credit score: Michael Hicks / Android Central)The COROS Heart Rate Monitor is excellent at one particular factor: coronary heart fee monitoring throughout exercises. Compared to a smartwatch that measures SpO2, temperature, AFib, HRV, GPS, and total sleep information, it is a restricted use case, one which matches the cheap worth. If you purchase the Polar Verity Sense as an alternative, you may get a strap with full water resistance, connectivity with ANT+ gear, and the flexibility to trace and retailer exercises themselves (although this will depend on the Polar app to trace them). So when you’re a aggressive swimmer, have gear that does not join with Bluetooth Smart tech, or prefer to work out and not using a cellphone or watch available, the Verity Sense may be a greater buy.None of that applies to me, although, and I doubt it will apply to many individuals trying to purchase this. They’re area of interest considerations, and COROS acquired the core stuff proper. I like that the 38-hour COROS HRM beats the competitors for longevity — Polar and Wahoo solely hit 30 — and that it depends on a standby mode as an alternative of an on-off button that you will very doubtless neglect to press when you’re again house and simply need to bathe and chill out. Unless you want waterproofing, ANT+ help, impartial exercise monitoring, or the larger accuracy of a chest strap, the COROS HRM is the strap for you.I do not take into account myself a severe sufficient runner to topic myself to carrying a chest strap frequently, no less than outdoors of evaluations. But with the COROS Heart Rate Monitor, it looks like I’m taking my operating metrics extra severely whereas additionally having fun with the comfort of a light-weight, sweat-resistant strap that just about by no means dies on you and takes ten seconds to placed on and alter.Even if this HRM does not match the “Perfection” label etched onto the band, it is about as shut as I might need. I am unable to let you know whether or not you “need” a coronary heart fee monitor strap or not, however as a semi-serious runner, I need it on my arm to reinforce my smartwatch. 

    The COROS HRM targets athletes who need higher than a smartwatch’s optical HRM can ship however cannot pressure themselves to put on a chest strap. This seamless machine merely works as quickly as you set it on and goes on standby for as much as 80 days as soon as you’re taking it off. It’s snug, safe, and reliably correct.
