@t1sugar I have been using the S7 for ski touring and found the OHR easily gets disturbed when using poles.
If you are waling/hiking without poles you should definitely be fine with the new HR sensor of the S9P

@isazi Thank you, I thought the OH1 was an optical belt, I should have been more specific in my request and asked for a comparison between a standard electrical chest HRM Belt. But nice comparison all the same.

@egika Thank you, I dont use poles much so this is very encouraging.

@t1sugar I do not carry a chest strap with me while traveling. But I have plenty of comparisons also with a chest strap, and results are good.

@egika mine seems to work reasonably well ski touring. It may be related to an individual. Both the S7 and S9P OHR on ski touring has been good but not perfect.

Interval training with S9P and OHR : 4 x 6 minutes R3. Seems perfect ! @Dimitrios-Kanellopoulos good job🤩

I am wondering why the GPX track is wobbling around so much!? (blue is S9P, watch on left wrist, orange is Apex Pro, watch on right wrist)

Trailrun/Speedhike with poles up to 20% gradient:

Hiking slowly with kids without poles. S9P left wrist, Apex Pro right wrist.

This track is really ugly compared to the Apex Pro . Any ideas why this happened? Only on the right end S9P did it better than Apex Pro when we were playing on that little river.

[Dimitrios Kanellopoulos]

@_marcus_ do you use glonass on both?

[Dimitrios Kanellopoulos]

@_marcus_ also right wrist always has better gps. Fyi.

@dimitrios-kanellopoulos same settings on both watches: GPS+QZSS, no GLONASS/GALILEO/BEIDOU

[A Former User]

@dimitrios-kanellopoulos ok, never heard of this. Why is it better on the right wrist?

[Dimitrios Kanellopoulos]

@_marcus_ actually I said it wrong. Left hand is better. That is because imagine you walking at a road. You walk at the right part and right you have trees wts

But if you want to test gnss please use the default setting (gps and glo) and same arm. Keep in mind that the watch that is higher should have a better signal.

[Dimitrios Kanellopoulos]

@_marcus_ regarding the wobble this is very interesting.

I wonder that the apex will record if you do a zig zag on a narrow road vs the s9P.

[A Former User]

@dimitrios-kanellopoulos it is a hiking trail and I did not walk around like a drunk person^^
The conditions on the worst part of the track:

And why is it ok on the way there but gets worse on the way back?

It is similar on hill repeats, more wobbling on the S9P.

[A Former User]

@dimitrios-kanellopoulos It used the same settings on both watches, I did not want to test especially GLONASS. I compared both with the same conditions except S9P on the left and Apex Pro on right arm.

[Dimitrios Kanellopoulos]

@_marcus_ Roger. I won’t argue. Just saying the the s9P is tuned for Glonass according to Sony. That’s why it’s the default. But I don’t argue to test that only. Just saying.

[A Former User]

@dimitrios-kanellopoulos ok, I activate GLONASS now. Did not know that S9P is optimized for that. Let’s see if it records better tracks

[A Former User]

@dimitrios-kanellopoulos

Question: Would it make sense to deactivate the options to only use GPS? Or does it still have any other significant advantages?

[Dimitrios Kanellopoulos]

@_marcus_ I am not so sure what you mean

Interesting. Do you have more (technical) detail?
