More Fenix 6X problems

When last I spoke about the 6X, I mentioned that they’d updated the firmware which vaulted the GPS performance from “utterly crap, I’d rather use a sextant” to “acceptable, but not as good as the 920XT”. Nothing has changed on that front. But I want to mention a few other things:

  1. I tried to use the “Race a previous activity” feature. On the 920Xt, this works pretty well. It shows your expected finish time, as well as how many minutes and seconds before or after that is compared to the activity you’re racing. Very useful for virtually racing yourself. I’ve tried it twice now on the Fenix, and I can’t make head nor tails on it. I’m a little handicapped that I don’t have my reading glasses in the boat, so I can’t read the field labels, but I thought I’d be able to logic them out. The field that I think should be should show the minutes and seconds faster or slower than the target starts off showing a time just a bit more than 2 hours (on a 1:33 activity). It still shows a time a bit more than 2 hours when it suddenly changes from white (meaning you’re that far ahead of the activity) to black (meaning you’re that far behind the activity). It also shows another field that shows your estimated time to completion and another showing distance remaining (which is handy). But without a usable time ahead/behind, I don’t really get information on whether I’m pacing it well, which is what I really want. So today when I did my regular “COVID Bassett” virtual Armond Bassett race, I had my Fenix showing the usual time/distance/heart rate/speed fields, and my 920XT showing the virtual race fields. I’m going to try using both and capturing it on video so maybe I can figure out what’s going wrong, and maybe show it to Garmin.

2. Garmin VIRB Edit, the software than I use for putting overlays on my videos doesn’t automatically pick up activities from my Fenix when it’s plugged into the computer the way it did with all my previous Forerunners (actually, I’m not sure if it did with the Forerunner 305, but definitely with the 310XT, the 910Xt and the 920XT). Instead I have to download the FIT file from Garmin Connect and upload it manually to Garmin VIRB Edit, which is annoying.

3. The Fenix 6 is utterly, 100% completely crap at reconnecting to the phone after they’ve been apart for any length of time. I charge my phone overnight in my office, but don’t take off the watch. In the morning, the 920XT would reconnect 99.9% of the time without any sort of intervention on my part. Just about every day, I will suddenly realize I’m not getting any notifications on my watch and go into the bluetooth menu on the phone to reconnect the Fenix. Today it disconnected while both the watch and the phone were on my surfski, less than 2 feet apart. My activity uploaded to Garmin Connect when I manually reconnected them afterwards, but for some reason it didn’t go to Strava. With the 920Xt, I was used to getting three notifications while I’m carrying my boat back to the car from the water – first one telling me the activity is on Garmin Connect, second one telling me it is on Strava, and third one telling me it is on Relive. I get that with the Fenix 6 more often than not, but certainly not with the certainty I would get it when using the 920XT. I may have to record a video to demonstrate how bad this is, since as I was writing this I realized my phone was in the other room, and when I went to pick it up it didn’t automatically reconnect to my Fenix.

Flow State

It is hard to explain just what an amazing feeling it is to start paddling away off on a long easy paddle. More than the thrill and challenge of a race or the good feeling of accomplishing a hard workout, just the feeling of strength and power and accomplishment, it is what keeps me going out day after day. It’s a very zen state when your technique is good and the boat is moving effortlessly.

You know, there were a few times in my skiing and orienteering lives where I was in a state where everything was coming together effortlessly and it seemed like I was just a sponge for sensations. I’ve heard it described as “flow state”.

I can think of very specific days when it happened, like an orienteering meet at Hilton Falls where I felt like I barely had to look at my map, I just knew where I was and where I had to go. Frank Farfan was taking pictures at one of the controls and he said I was the only one who ran straight in and straight out of that control without a moments hesitation and the whole race was like that. I believe the picture he took of me ended up in the International Orienteering Federation newsletter.

Another time was on the second day of one of the Canadian Ski Marathons I did. It was a gorgeous day and I remember double poling down a gentle incline and passing a guy who said “Il fait beau, eh?” and that just summed up the entire day for me. Perfect skis, perfect wax, perfect snow, perfect day and a real feeling of being one with everything.

I was watching some YouTube videos the other day from a guy who had a v12 surfski with hatches and bulkheads that he was using for kayak tripping. I’d be damn tempted to go travel the waterways of Algonquin Park again like I did 40 years ago if I had hatches and bulkheads in my V8 Pro. They probably have sleeping pads that don’t hurt by now.

More updates on the Fenix 6X front

Garmin replied to my support ticket to say that they were working on a patch to fix my problem and they’d inform me when it was ready. Then yesterday when I plugged my Fenix into the computer it did install an update, but I wasn’t sure if it was “the one” because they didn’t inform me. I decided to take both the Fenix 6X and the Forerunner 920Xt out on the canal to make another comparison.

My impression while paddling is that I didn’t see any ridiculous speeds this time, but the Fenix was reading a little higher than the 920Xt much of the time. Also, by the middle of the paddle the Fenix had the distance about 20 meters further, and by the time I finished it was nearly 40 meters.

I threw both FIT files into DC Rainmaker’s Analyze tool and found a few things.

GPS track comparisons

The first thing you see is that both tracks go a bit wonky around these bridges (and others not shown here). The purple line is the Fenix, and the blue line is the 920Xt. When I paddle downstream I tend to stick towards the middle of the canal (the upper lines) and when I return I tend to hug the inner shore. I can assure you I didn’t make a sudden jog to the left bank at Monroe Avenue as shown in the upper Fenix track or a sudden jog to the right shore as shown on both tracks. Same with the bridge at Schoen Place – the Fenix track shows me way too far north and the 920Xt track shows me making a sudden jog to the south, neither of which are correct. Overall the 920Xt seems to do a better job of showing my actual track, but the Fenix isn’t terrible.

The speed graph comparisons

Overall, it looks like the Fenix speed has been more aggressively smoothed, or maybe it’s not sampled as often. There’s a weird peak at the 16 minute mark where the 920Xt is showing 10.1 km/hr and the Fenix is showing 12.6, but otherwise they’re close. And not surprisingly, the spike occurs while passing under another bridge, State Street, which is also a steel bridge with big trusses.

Speeds zoomed in a bit

When I zoom in you can see that the 920Xt speed is changing much more frequently than the Fenix. Come to think of it, I remember setting my 920Xt to sample every second – that might be something I need to do for the Fenix as well. You see a similar smoothing effect (or lack of sampling frequency effect) on heart rate even though they’re both paired to the same Wahoo TIKR heart rate strap.

One thing everybody should know about GPS watches is that their altitude information is terrible. And these two watches are terrible but different.

Elevation data comparison

The Fenix is consistently higher elevation that the 920Xt, but with similar shape of ups and downs (on a practically flat canal). Only 3 or 4 meters elevation difference between them most of the time. I can’t find any obvious cause for the weird dip at around the 33 minute mark on the 920Xt as I’m nowhere near any bridges nor am I particularly close to the concrete walls of the “Washing Machine”. But that’s ok, I usually remember to click “Elevation corrections” on Garmin Connect and Strava after it’s uploaded. I think what they do is correct your elevation to what a digital elevation map says your elevation should be at each location point.

At this point I’m just about ready to declare myself ready to use the Fenix for normal paddling. I’ll do a few more head to head tests first, though.

Garmin Fenix 6X, a mixed bag

So Garmin is having a big spring sale, so I decided to treat myself to a Garmin Fenix 6X Sapphire. It has some amazing features – too many to list here. I had it in my head that I might be able to use it instead of my Forerunner 920XT, but I might have to hold on to the 920. At first I was thinking it would be a good replacement because the screen is big and clear. But I’ve paddled with it twice, and it has a really annoying bug.

When you’re paddling, every time you paddle under a bridge or too near a concrete wall, the watch would lose GPS satellite signal. Every previous watch I’ve had (Forerunners 301, 320, 910Xt, 920Xt) would show a slow speed for a little bit, then it would show a high speed for a little bit, then would settle down and show the correct speed again. Not this guy – instead it shows a blank screen for a short time, and then it shows some crazy impossible speed. Today at one point it was showing 886,844 km/hr. That’s 30 times as fast as the International Space Station in orbit, by the way. If I really hit that on the canal, I’d probably evaporate all the water from Buffalo to Albany.

The worst thing about these huge spikes is that it makes my speed graph unusable. Two days ago I paddled with the 920XT on my boat and the Fenix on my wrist. This is what my speed graph looks like from the 920XT.

And this is what it looks like from the Fenix.

Useless.

Now I remember from reviews on DC Rainmaker that the Forerunner 945 had some accuracy issues because they’d switched to a Sony GPS chipset to improve battery life. I assume that’s what the difference is here as well. Hopefully there will be a firmware update to fix this.

Interestingly, it appears that Strava has done some sort of smoothing, because my speed graph looks normal on it, with a max speed of 13.7 km/hr instead of 888,000.

Update

Got an email from Garmin saying they’re working on a firmware fix.

Shameful Confession

Several years ago when I was working from home completely, I decided I needed a really good chair. I did a bit of research and bought a chair that was advertising how much they customize it and how ergonomic it was and all that. It cost more than a Herman Miller Aeron Chair, even if you didn’t buy it from a 90s era startup that had gone bust, but I thought if it saved my back it would be worth it.

Ok, first problem was their amazing customization was basically asking you three questions and then picking either a small, medium or large lumbar pad. I was expecting bespoke and I basically got off the rack. And it wasn’t very adjustable after it was delivered. I was lead to believe there would be a call with a consultant on how to set it up or a comprehensive manual, and I got none of that.

Second problem was that they insisted it had to be delivered via an 18 wheeler, like this was a major selling point or something. This chair was no bigger than any other office chair and it could have been delivered by a panel van, but they insisted. And so I get a phone call from a delivery driver who doesn’t know how he’s getting his gigantic rig down our tree covered residential neighborhood streets. I tell him to deliver it with a panel van, he says he can’t and suggests I come out to meet him somewhere and he can give it to me. I say there’s no f-ing way I’m going to do his job for him. So lo and behold a little while later this truck comes down the street, slapping tree branches all the way, and delivers this package that’s no bigger than other things UPS has delivered in the past.

So anybody, I spent way too much on a not very comfortable chair, and I was embarrassed to admit it, so I’ve kept this chair for about 8 years. And if this lockdown continues for much longer, I’m not sure if my back can take it. And I’m not sure I want to order a chair without trying it, and that’s not going to be possible.
