hi everybody welcome back to Wesknows tech news and reviews today we'll be doing an accuracy test
of the gps and heart rate accuracy between the coros pace 2 and the amazfit gtr 2e so
without further ado let's get into it if you're new to wesknows tech news and reviews we talk
about the latest tech news we do brutally honest reviews and share hacks and tricks along the way
now let me tell you about the test rules so basically i was walking down from hammersmith
bridge all the way down to putney bridge the distance there is about 2.6 2.7 kilometers
somewhere around there but i was actually tracking the distance with my samsung
s10 plus on the polar beat app and it has shown me a distance of 2.61 kilometers now the heart
rate benchmark will be performed by the polar h10 ecg chest strap which was across my chest
all the time during this walk so let me quickly tell you about the two sport and smart watches
we've got in front of us today and why i've chosen them in particular so first of all the core space
2 this is a full-on sport watch it's got training guides it's got training program it's got dual
inbuilt gps it's got an always-on display this is a sport watch from the chorus brand and it's
actually the only sport watch under 200 bucks and this is a true competitor to garmin sport watches
now i actually brought along the amazfit gtr 2e for a reason so this is a smartwatch but we've
had a lot of problems with gps accuracy as well as heart rate accuracy from the optical heart
rate sensor on the back of the gtr 2e previously but we've been told that a mass fit has actually
updated its firmware on the gtr 2e as well as the gts2i and it has improved the gps accuracy as well
as the heart rate measurement accuracy and we are going to check that so the amazfit gtr 2e this is
a 1.39 inch amoled display looks absolutely amazing a 30-day battery inbuilt gps water
resistant it's got it all apparently but let's see if it's got the accuracy so first let's look
at the gps so as we can see on the screen right now we can see that the samsung s10 has actually
measured a distance of 2.61 kilometers let's have a look what the chorus pace 2 came up with we can
see that it shows us a distance of 2.51 kilometers so that is off by just under 4 by just 3.8 percent
now let's take a look at what the gts2e has come up with 2.95 kilometers that's off by 12
well just under 12 but that is absolutely massive so of course if previously the differences were
as much as twenty percent now we're down to twelve percent in improvement definitely but
is the result spot on no not yet but that's fine let's take a look at the heart rate accuracy next
okay so with heart rate accuracy we can also see that the polar h10 ecg chest strap has actually
come up with two values so the average was 102 beats per minute over the wall while the max was
registered at 115 beats per minute let's take a look at what the core space 2 has actually
come up with so this is the optical heart rate sensor on the back of the chorus pace 2 and we
can see that the average was spot on also 102 beats per minute while the max was understated
by two beats per minute at 113. so this is quite amazing so at one point the max was not registered
so the peak was off slightly but the average is spot on and this is over 35 minutes of walking
so there are quite a few data points on there let's take a look at what the amass for gto2e
has come up with so this particular test is actually quite easy for the optical heart
rate sensor on the back of the smartwatch because this is a low intensity activity
so this is where the heart rate is rather stable across a period of time it's just walking it's not
running and let's look at the result so the result shows us that the average heart rate was measured
at 105 beats per minute while the max was registered at 121 beats per minute that is
off so we are saying it's not massively off but it's three beats per minute high on the average
and it's six beats per minute higher on the max showing us that yes even though the heart
rate accuracy was improved gps accuracy has also been improved we can still see that it's still
out quite significantly anyways thank you for watching this gps and heart rate accuracy test
