Garmin Activity/Fitness Trackers — Issue With ‘Pool Swim’ vs ‘Open Water Swim’.

This issue as to the difference between ‘Pool Swim‘ vs. ‘Open Water Swim‘ comes up repeatedly in the context of Garmin activity/fitness trackers/watches such as the Vivoactive 3 and Forerunner 645.

The Vivoactive 3 and Forerunner 645, in particular, do NOT support ‘Open Water Swim’ though they do support ‘Pool Swim’.

This distinction and restriction drives folks nuts, so, I decided to get to the bottom of it.

It has all to do with GPS/Glonass support — or lack thereof IN WATER.

GPS does not work very well when the sensor is submerged in water. THAT IS THE CRUX OF THE ISSUE.

If you just want a GPS distance and track while you swim in open water you could try putting your watch into running mode and having it attached to a swim cap. That is supposed to work.

‘Pool Swim’, by definition, means that GPS is DISABLED. Pool swim data is measured using the ACCELEROMETER. Got that? No GPS … just accelerometer.


So, how do the more expensive watches like the Garmin Forerunner 935 and Fenix 5 support open water swimming? They use the GYROSCOPE.

With the gyroscope you only need occasional GPS fixes. The gyroscopes fills in the gaps between the GPS readings. The Vivoactive 3 does NOT have a gyroscope. Hence why open water swim is not available.

But, alas, a gyroscope alone is also NOT enough. For open water swim you ALSO need a powerful enough CPU to continually calculate the data. Got that?

Hence why open water swim is not supported on the Forerunner 645 though it has a gyroscope. The CPU in it is not as powerful as that in a FR935. Got that.


So, that is the deal.

To get open water swim support you need a gyroscope and a big enough CPU. Without that you only get pool swim which only uses the accelerometer.

You can TRY and use running or pool swim in open water — though the results will be mixed and most likely inaccurate.

So, that is the story. Now you know.

Google Chrome Unbeknownst To YOU Is Hogging A Ton Of Your Computer Power — Apply This Simple, Safe Fix.

IF you use Chrome, and you really should, since it is the BEST Web browser, by far, around, you right now are losing a LOT of computer power because of a bug between Chrome and Adobe Flash.

You won’t see it. It just results in HUGE unwarranted PC CPU usage — which will slow down other work, generate lots of unnecessary (and always damaging) heat and if you are using an unplugged laptop SAP your battery life.

If you want to get technical it has to do with the Flash ‘Shockwave’ plugin used by Chrome to display Adobe Flash content … and many, many, many Websites still use Flash for their animation.

This Plugin (or a part of it) is going into a loop.

There is a NEW Flash version floating around. Install that. Not sure whether that will fix this problem.

But, this easy, safe fix that I am going to tell you WILL. I applied it, without any problems hence, 2 nights ago.

CPU usage is NOT a problem on this PC. I have 4 genuine Intel i7 cores that run 8 threads. So, I only noticed this bug BECAUSE the CPUs were generating excess heat because of the tight loop. As I have mentioned earlier, this PC has 7 fans — the speed of the four chassis fans controlled by the Motherboard based on CPU temperature. Most of the times these fans run ‘quiet’. BUT, if I hear them speed up and the PC sounding like a jet revving up for take off I know that my CPUs are running hot — even though ‘hot’ in this case means that there is still 40% MORE heat capacity left! Yes, I over-engineered this PC.

Chrome has its OWN Task Manager.
Very safe and easy to USE.
Just hit SHIFT + ESC.

Here take a look at what the Chrome Task Manager looks like.

Notice the Plug-ins at the bottom. IF you see that the ‘Shockwave Flash’ has MORE than ‘1’ against its CPU use … YOU need my fix.

Fix is very simple. I found it on the Web, on a Chrome Forum, after some fast but incisive Googling.

Type in chrome://plugins into the URL (Address) trench. When the Plug-ins display in a Chrome tab, go to the RIGHT HAND top and click ‘+ Display‘.

You will then see the TWO entries, files, for Adobe Flash Player … at the Top.

Just disable the entry that has ‘PepperFlash‘ in its file name. That is it. You are all set. Bob, once again, will be your uncle.

David Nix Of Belmont, NH: Finally A Competent, Credible & Reliable Computer Person In The Lakes Region.

To say that I am fussy about my PCs, especially my main ‘work’ PC, would be beyond an understatement. Lets face it, one way or another, in essentially three shifts, the last ending well past midnight, I spend at least 10 hours a day on my main PC, often more. When I have problems with my PC I am not a happy camper. It ruins my day. Yes, I have two backup computers, but they are not as brawny as my main PC.

PC hardware is not my thing. All the wires, connectors and setup is way too tight and delicate for my liking. So I always have somebody, somebody good, do my hardware. Once Windows is up I can do the rest, but I won’t touch the hardware (other than cleaning it out with compressed air once a month). Suffice to say I am always in the look out for competent, reliable hardware folks that are reliable and trustworthy. In my experience this has been a scarce commodity in the Lakes Region. A couple of folks I have used in the past have moved on. Over the last 3 years or so I have had real troubles finding anyone.

I have given up on those that now advertise on Craigslist. I don’t know why they bother. You contact them and they are basically not interested. They say they will call or that they will come, but you never hear from them. Maybe they are just waiting to get calls from ol’ ladies that they can rip off.

I had ended up using somebody I had met at BestBuy, who lives in Hillsborough, to do my hardware. But, it is a 90 drive for him and he works crazy hours.

A couple of weeks ago, when I was crazy busy with the sede vacante, I started getting funny noises coming from one or more of my fans in the PC case — and the case alone has 4 fans, not counting the ones on the i7 chip, the video card and the power supply. I really needed somebody to come and look at the fans.

Tim Croes, of ‘The Baysider’, had just interviewed me and he was coming around on election day. I e-mailed him and asked if he, as a local, knew any good PC folks.

He e-mailed me back with David’s name and phone number. I called. He was very pleasant. He said he could come over in 2 days. That was fair. We got talking. I asked him if he was related to Stephen Nix, the Real Estate/Property attorney in Gilford. He was. Steve was his brother. I had used Steve, maybe 11 years ago, when I had a mooring buoy issue when I lived waterfront in Gilford. Steve took care of it for me very efficiently and affordably. I was impressed. This was a good omen.

David came last Wednesday. He cleaned, reseated and checked out all my fans. My rear 140cm fan was not working. I needed a new one. I ordered one. David came again today and put it in.

I like David. He is good. He is in his early 50s. So he is not a ‘kid’ per se. He knows what he is doing. He is careful. He is thorough. He is also very reasonable.

He is a musician, has been a ski instructor at Gunstock for decades and is from a local family. All around good person.

I am impressed. I recommend him.

If you need any computer work contact David. You will be glad you did.

One of the 7 fans in my PC, this the CPU fan on Intel i7 chip.
