Polar Grit X ‘all black’ at LEFT.
My Garmin Fenix 6 has the Titanium Bezel.
When in ‘smartwatch’ mode they are very DIFFERENT.
Like chalk & cheese.
As you can see from the top 3 pictures the distance & time were on par with my Garmin Fenix 6.
I can’t say which one is more accurate, but I know that the Garmin Fenix 6 is ‘OK’ — in that I have tested it against multiple other watches, including the new Fitbit Charge 4 (just a couple of weeks ago).
If the Grit X readings had differed widely I would have been concerned. They did not. They stayed within ‘spec’.
This was also true for the elevation & Heart Rate (HR) data. The Polar & Garmin were pretty close to each other.
So, that is good. That is a start.
I will publish more pictures and data soon.
This was a first cut after having the Grit X for 2.5-days.
As soon as I saw the headline in the U.K. ‘Daily Mail’ I knew it was going to be amusing. To be fair, and to their credit, they did make a decent enough fist of trying to explain the ‘dilemma’.
And what is that ‘dilemma’. When we are talking about stars, including our own Sun, we have to factor in the delay it takes for light from it to reach us. In the case of the Sun it takes 8 minutes and 20 seconds. Has to do with the enormous distances involved and the speed of light (which, though very fast, is only ‘that’ fast). So, if something was to happen to the Sun it would be 8 minutes and 20 seconds before we saw anything. Just the laws of physics.
Betelgeuse is ~640 light years away. That means it takes light from Betelgeuse ~640 years to arrive to us, on Earth.
So, we are seeing Betelgeuse as it was ~640 years ago!
Think about that.
When looking at stars we are always looking way back … into history.
We just have NO, NO, NO WAY of knowing what is happening at Betelgeuse right now.
All we see is what happened ~640 years ago.
So, it is difficult to write about ‘future’ events involving stars. The event might have already happened! We just don’t know.
That is the problem with this article. Betelgeuse could have already exploded — without us knowing.
Think about it. It is cool. SMILE.
P.S., All the stars that make up Orion are not the same distance away from us!
Betelgeuse is much closer than most of the others in that constellation! Something else to think about.
Garmin’s ‘Vivomove Luxe/3’ & Vivosmart 4 Now Get ‘Connected GPS’ — Provided You Have Your Smartphone Handy.

What I find here is that these watches did NOT have ‘Connected GPS’ from the get-go.
I have only ever bought Garmin, Fitbit or Amazfit watches with GPS so I have never required ‘Connected GPShttps://www.garmin.com/en-US/blog/fitness/connected-gps-now-on-vivosmart-4/‘.
I know that it has been available with Fitbit for a number of years. I have heard people talk about it. Thus, I had just assumed (incorrectly, of course) that Garmin must also have this capability by default.
The ‘Vivosmart’ is a $130 band. I can just about fathom why it doesn’t have GPS. For $40 more, you can get a ‘Vivosport‘, with GPS and a color display. That is what I got my wife.
The hybride ‘Vivomove’ with fixed hands and hidden color touchscreen is a $350 to $550 watch. You would think Garmin would offer GPS — maybe even as a $50 option. Guess not.
I love GPS on my watch. I use GPS, near daily, if I am doing a serious walk/run or hike. I do it to get (hopefully) a better distance measurement, i.e., GPS rather than accelerometer and gyroscope. Yes, GPS still leaves much to be desired, especially if you double back on yourself or walk in circles. But, I convince myself that the milage it shows is within +/- 5%. Yes, I have tested distnace with multiple watches (given that I have had at least 12 over the last 2-years) and vehicles.
Using the phone GPS is not the same. Yikes. I feel bad.
Very frustrating. And I am a Garmin shareholder to boot. Yikes.
This article held no surprises for I. I knew the Garmin Vivoactive 3 GPS was pretty accurate. I had clocked it against a car odometer — albeit in the 3.5-mile range, rather than at the marathon distance.
That the Garmin Vivosmart 4 was inaccurate should not be a earth-shattering. It doesn’t have GPS.
That most of the other watches were quite inaccurate too is more of a concern. I owned a Samsung S3 Frontier. That, at the 2-3 mile range, was pretty accurate.
But, this is sobering.
I tested a low-end Fitbit recently and could not believe how inaccurate it was. It was a joke.

Today for the first time I had ‘Auto Pause’ enabled on my Garmin Fenix 5 Plus. I went for one of my usual runs — with my two dogs (Golden & Harrier) who do like to stop OFTEN. So, yes, auto pause was kicking in and off — quite often.
This is a run I do, on average twice a week, and have done so for nearly a year. I have run it while wearing: Garmin Vivoactive 3, Fitbit Ionic, Garmin Fenix 5, Garmin Fenix 5 Plus & Polar Vantage V. So, I know what the distances are and do so across multiple watches. I also do this run most of the times with the dogs.
Thus, the only change today was ‘auto pause’. I get to the driveway of my friends’ — and you can see the little squille (top right) when I detoured to see them on a prior run. The GPS reading should have been around 1.6 miles. Today, it was not. Close to 1.5. That was wrong. I ran to my usual 1.75 point. It read 1.6! I ran further. This was further than I have ever run on this route before. I got to 1.65 miles. I gave up. Turned around. I knew I had done 1.75+ miles.
Came home. Didn’t make any detours. Straight back and you can see that. When I got home it read 3.53 miles!
I had turned around 1.65 miles. 1.65 x 2 is 3.3 NOT 3.53.
So, obviously GPS was catching up on the way back.
NOT AMUSED. Turned auto pause off. Screw that for a game of checkers.

It has been BLOODY cold in New Hampshire for the last 2 days — and those that know me, and know that I will still go running in 5°F weather, will know that IF I complain of it being cold, it is pretty serious.
This, my friend, is NOT right and there is no damn, frigging Global Warming in sight — at least not in frigid New Hampshire. I would LOVE some Global bloody Warming. I need to renew and top up my tan. Relying just on tanning creams becomes and expensive and messy hobby.
Yes, of course, we have seen Climate Change BUT that is because the DISTANCE of the Earth’s orbit, from the Sun, has changed! You did NOT know that did you? Most people don’t. Why, the Earth is getting lighter despite the increase in obese folks, worldwide. Yes, I need to write about this in detail — but I don’t have the time. It is the Earth’s weight, of MASS if you want to be pedantic and scientific, that is changing. Greenhouse Effect is NOTHING. It is the distance from the Sun that counts. Remember I do know my astronomy.
Check these out. It is June 2nd and I am forced to wear sweats — though sweating is the last thing that is happening around here.

**** Check my ISON blog.
Comet ISON prospects, quite literally, are getting brighter by the day.
It is intact and is becoming more ‘active’, i.e., spewing out more gas and dust which is what leads to the coma and tail, by the minute.
Right now it is travelling at more than 10 miles PER SECOND. That is in excess of 38,000 miles per hours. So it is getting closer to the Sun at a very fast clip.
Ameteur astronomers using backyard telescopes are capturing some amazing pictures. Check this one from October 5, from Austria (that is in Europe).
On November 2, 2013, i.e., next week, it will cross Earth’s orbit for the first time, i.e., inbound (towards Sun) crossing. Check this post for orbital diagram.
But, on that day Earth is way off to the right — 112 MILLION miles away, that is 1.2 x the Earth-Sun distance.
So, we will not be able to see Comet ISON, naked eye, on November 2.
The EARLIEST possibility for a potential glimpse is November 17 — some of this also having to do with moonlight getting in the way.
Closer to the 17th, as things become more clear, I will post an update.
It might not be the ‘Comet of the Century’, but it is still on track to be one heck of a comet.
Russian Meteor Fireball Explosion: The Conspiracy Theory. I Think It Was Manmade, Intentional Or Otherwise.

As I have intimated of late, I have been spending most of time studying and writing about Near Earth Objects (NEOs): asteroids, comets and man made objects [e.g., satellites, spacecraft and debris].
As soon as I saw the news about the Russian meteor a thought crossed my mind. This could have been man made!
Yes, it could have been space debris, probably Russian, given that they were notorious for their littering of space (some due to all of their many spacecrafts that blew up). But, could it have been intentional. A drone? The U.S. checking out Russia’s much speculated space defense.
Bottom line: I am not convinced that this was a chunk of an asteroid or comet. It could have been. Just something tells me that this just didn’t seem right.

This is Way Cool.
A dynamic orbit tracker from NASA’s JPL.
Try it out if you have Java installed.
It was discovered last year, on February 23, 2012, by a Spanish observatory.
It is an Earth-crosser asteroid that orbits the Sun every 366.2 days. Since it furthest point from the Sun, aphelion is beyond Earth’s orbit, crosses Earth’s orbital path twice a year. It has been probably been doing this for millions of years, though we now have precise data going back to August 1913.
It is not very big, about 160 ft across and weighing about 180,000 tons. It would do a fair amount of damage if it were to hit the Earth. It will not do so this year! But this is a record close approach. So much so that Earth’s gravity will perturb its orbital path reducing its orbital period by 51 days. That is a big deal.
There is an increasing chance that it might actually get around to hitting the Earth post 2080 — so 67 years from now. So our kids will have to keep an eye out. Asteroids of this size do hit the Earth every 1200 years or so. We are due. DA14 would not be the end of the World. It is too small. It could destroy a city. There was smaller asteroid that entered Earth’s atmosphere, above Russia, in 1908 and exploded in the sky before hitting the ground. It destroyed about 80 million trees over a 830 square mile area,
