@isazi amazing bike trace this morning in GPS (+Glonass/Qzss) : in the wooden area the track overrides the route , almost like a snap to route :

I add to zoom to see the route :

Did somebody test the route tracking ? Any GPS losses ?

maybe me
I was navigating a route while exercising, and a couple of times i was out of route, but it came back quickly. So i didn’t notice too much.
But once, i was looking at route screen, and GPS was lost at this time.
Is it what you mentionned ?

@ink357 I did. Only once I noticed ETA was displayed as “–” and restored itself after a short time. I’m not sure if is because of a reception problem.

I did notice that the track was incredible close to the route so I don’t think accuracy is an issue in the open field. Didn’t try the forests yet.

@mff73 exactly. I use to trail on routes i don’t know and the route tracking is very important to me (i also take a map and my phone). In the last workout i made with my S9B, there were a lot of GPS losses. It could be boring…

Today I charged the S9P for the first time from 13% to 100% and it took only 52 minutes!

Up to 80% took only 25 minutes. After 90% things slowed down a little bit. In the last 2 minutes, it snapped suddenly from 95 to 100%, probably due to a recalibration of the battery since it was the first time…

I did the same test as you, but like a lazy guy
I let the watch register the data with a non GPS, non HR mode, and let QS show me the result

From 33% to 100% in 43min with same pattern
80% reached in 17min, wow !

@ink357 I have had no losses and did an 11h run on Saturday.

ink357

@brad_olwin sounds good. What do you use ? GPS + ?? Or only GPS ?

pschenn

@mff73 That’s smart to do it like that!

Only GPS, I’ll post some data this evening, been busy.

@isazi today time to compare OHR with polar H10

Run OHR/Polar H10 comparison

Everything started well, but after 5 minutes OHR was continuously +40 over.
Maybe started to sweat ? incorrect placement ?
Not tightened enough ?

Dimitrios Kanellopoulos

@chrisc92 is this running ? Maybe sweat. Just in case next time try to clean the sensor of sweat.

Just saying. No clue though.

chrisc92

@dimitrios-kanellopoulos yes just easy running at Z2 , my Hr is 45-160, my Z2 stops at 130, tomorrow i will tighten the wristband and try the comparison again to understand, because the first minutes were so close.

The sensivity of autopause in openwater swimming is not as good as I remember from the Ambit3peak. During constant movement with higher speed in crawl it automatically stopped, but did not start again. I had to continue very often manually. In the end, about 300m was missing on a known distance of about 1600m. Gps was set in performance mode +Beidou.
I also miss a data field for the number of strokes. Unfortunatly the SA shows no swimming metrics like strokes or strokes per minute.

I am really mixed with this S9P.
Really comfortable, quick charge, 24/7 HR is nice (i come from SSU without OHR )
GPS is not that exceptionnal in my area (tried GPS+Glonass, then GPS alone, then GPS+Beidou). It is good, but…
And fused alti is strange to me.
Latest run, GPS altitude vs recorded altitude

Start and end altitude are GPS OK (385m), but not recorded one (425m).
Max altitude is somehow correct (510m)

During cycling in endurance mode I had very often Gps signal losses partially over 2km long, despite almost clear visible sky, both with Gps only and Gps+Beidou. I had to manually switch to navigation or switch to Gps performance mode so that the signal was found again.
In addition, I can only recommend autopause in Gps performance mode, otherwise it can come to automatic stops during the ride and there may be no automatic start for several kilometers.

Dimitrios Kanellopoulos

@mff73 I don’t see a problem ?

Dimitrios Kanellopoulos

@mff73 oh you refer only to gps altitude right ?

Mff73

@dimitrios-kanellopoulos
Not really, I compare GPS altitude (registered by S9P) with “fusedalti” saved altitude.
And there is quite a “big” of difference.
Isn’t it? Or it seems normal?

Brad_Olwin

@wotus Why are you using Endurance mode? It is not meant for cycling as FusedTrack will not work. Endurance mode is typically for running/hiking.
