. They both have the same optical heart rate sensor on the back, which is a different variant. Different diode colors than the grit x and the polar vantage v2, and it looks very much like the similar to the original ignite original m. So we’re going to test the accuracy across a number of crossfit workouts we’re, going to look at how the diodes look compared to the technology on the vantage v2, which is the same color diode scheme as the grit x. So we want to test and see the accuracy i can’t say if this is the polar precision prime 1.0, but i think that’s probably what it is, but either way we’re just going to test the accuracy and we’ll take it for what it’s worth. So you know what the accuracy is for doing a crossfit workout wearing it on the wrist and seeing what it gets. Now, as we do the accuracy testing for crossfit workouts, we always track it across a number of things, so number one. The average heart rate for the beats over 100 beats per minute, so we don’t care about the first 100 beats per minute. So we assume every optical heart rate. Tracker in the universe will probably get that probably right. What we care about is how accurate is it above, 100 beats per minute just on the average heart rate for the workout. Secondly, we want to track the zone five, which is from your maximum heart rate, based on your age or whatever calculation metrics.

You use the 90 to 100 percent of exertion, so the absolute peak level of heart rate exertion in the middle of a workout, as we know, with crossfit and high intensity interval training whenever you’re doing the workouts, you’re, typically spiking your heart up for a period of Time maybe you’re doing an intense and ramp for a period of time, taking a rest and 10 sam wrap taking a rest, but either way we want to track that most intense to see. Can the optical heart rate keep up with the intensity of a crossfit or high intensity interval workout behind that we’re testing, the percent to a hundred percent, so the zone four and five? So, obviously, again, just the high high upper echelon of your maximum heart rate to see if it can keep up and then last because it’s a polar device and i’m testing it against an h10 chest strap when linked to polar beat. We want to test to see what the evaluation is for cardio load now for polar users. The cardio load is what’s tracking the intensity of your workouts over the last seven days versus the last 28 days to see if you’re pushing your fitness to new levels, because the intensity of workouts is getting higher and higher. So it gives you a score: a cardio load score at the end of every workout, so we can test it with the chest, strap and get a score there and with the watch itself, just on the wrist and get a score there and see how much accuracy Is actually going to flow into your load tracking over time so that you can evaluate your fitness and your fitness growth so with that let’s, look at the sensor, if you like the video, please give it a thumbs up.

Please consider subscribing for more on what’s. Coming up next, obviously, and maybe more implied, it’s just a review for the m2 is a review for the ignite 2, as well as a review or a comparison just of those devices versus some of the other devices that are on the market today. So let’s look at the hardware and then look at the overall results of tracking the workouts and come back together. Okay, so there we can see the optical heart rate sensor, flashing in red it’s flashing, like a million times faster than the video is going to pick up. You can see both of them still flashing here and if you were to compare it to the polar vantage v, you see a different color scheme, so we’ll see if we can get both of these to fire at the same time. But you have red green and red on this one, and then you have orange red with one green in the middle on the original precision prime 2.0, on the vantage v2, as well as the grid x, so that’s the differences that you’ll see. Does it affect much? You know, one thing i will note is that the the reason we only tested it on one watch only tested on the vantage m2 versus testing it on both the ignite 2 and the vantage m2 is it’s. Really the same. It’S got the same elevation the same sensor. Everything about it is just the same, so no need to test both devices to get an accuracy for both devices.

So with that let’s look at the software all right, so we can see you know just a whole bunch of workouts so i’m not going to go through all these. You know you can see the average heart rate versus the cardio load score on the m2 versus the heart rate. So 137 was the average and 108 and you can look at the charts. I think the biggest thing to see is just the chart differences. So you get this, you know, sort of scattered line on the m2 versus a clean line on a chest. Strap scattered line were a little bit cleaner lines that wasn’t as intense. That was more of a heavy lifting session. You can see differences here. It missed the middle gap, so obviously it did not keep up with the intensity. The m2 versus the intensity sort of staying continuous on the chest, strap m2 higher level and consistency on the chest. Strap this one is just a low workout, but also just wasn’t as higher levels. Again, a heavy lifting workout and you can see. Well, you see a metcon at the end, so it totally missed that altogether, plus it didn’t pick up the intensity of the lifting portion um and if you get to this workout for today, this was a brutal workout was um like a filthy 50 with a partner Wad, so lots of intensity. It did actually pick up a lot of intensity, but it didn’t pick up enough of it, so like 30 minutes in the peak highest level zone.

So what does that mean for the results? So we can see the results here. You know. I sort of color code things so that it comes in um sort, a b, c d f as far as like a rating, so the red is like failure um. This is taking out the bottom two performances. So if i just assume there’s a couple workouts where i was using uh wrist wraps as well as i mean hand, wraps hand, grips and um, i think there might have been some disturbance on the watch. So i just dropped the bottom two, but you can see a lot of red when it comes to picking up the zone. Five on the cardio load, like with what’s gon na, have value to help you track your workouts and training over time. It’S getting sort of mid 70s, it had one good one from today, so that was great, because that was a long, intense workout. But what do the averages all total up to be? We can see that’s about 85 percent, accurate for just the average heart rate and that’s, not a great number, because typically that’s closer to more accurate, 90 or above the load tracking, so it’s going to miss 18 of your load. So your load is going to be falling short from what it really is. The zone 5 is obviously where the big failure point is and zone four and five. You know still just getting a missing 25 percent of the max heart rate across the top 80 to 100 percent of your peak heart rate.

So what is this and so again in these numbers? I dropped out the bottom two performances so i’m, going to show you all the results. So if i look at this, you know if we drop the bottom two 72.8 percent, so i mean it’s missing 28 of the workout exertion, the highest level workout highest level. Exertion points if you drop the worst, the one worst workout at 68, accurate and if none of the workouts were dropped – 64 accurate. But if you just take the top two numbers and you sort of assume that that’s relatively in the accuracy range i’m going to say. It’S 70, accurate 30 inaccurate, so it’s missing 30 of your highest level exertion, so i think that’s sort of the bottom line to take away from it. So let’s come back together. So what do we see in the results? You know if you take out the bottom. Two outliers and again i was wearing wrist straps or hand wraps, and you know so it could have disrupted a couple of the workouts. So i first dropped the worst one out and then i dropped the second two worst ones out to get average scores and as we saw on the results you know we take, you know the let you know take the two worst scores out. It got a 72 percent accuracy when you take the one worst score out. It got a 68 accuracy, so in general i would say: it’s 70 accurate now that’s that’s fair when it comes to crossfit, workout, tracking, that’s, sort of on par with what a lot of devices are doing and it’s a little bit better than i actually got in The accuracy testing of the polar precision prime 2.

0, which is on the grit x’s on the vantage v2, so again, it’s medium. What does all this say? Number one? It says that it’s missing the top 30 percent, the most the the highest and most intense exertion on your heart. It is not capturing so that is a that’s, an important metric, so as you’re doing crossfit and high intensity interval training, the ability to capture that peak, most rigorous zone and most highest level exertion on your heart is super fundamentally important, so um the other thing that It helps us to see is just use a chest. Strap, you know polar is known for their linking to chest straps. Obviously they have a whole line of chest. They have the polar verity sense, which came back at 99.3 percent, accurate when doing on a crossfit workout across 10 workouts. So we see a lot of accuracy there, so don’t risk it just connect it to a chest, strap if you’re doing crossfit or high intensity interval. Training, you just want to have something that’s going to give you accuracy because, as we all know, with the watches that flows into your load tracking, which helps you evaluate your fitness.
