Today I hear about continuous resets, having to wait sometime after sync so agps files can do this and that on the watch, plus gps firmware.
Ok, so what is the added value that this new devices bring in order to compensate all the trouble (sincerelly asking)

How many resets did you have? Just curious.

With the ambit 2? None. Ambit 3 one.

@André-Faria with my s9 none. With my s7 none. With my Spartan none.

So the point is not how bad are our watches, the point is about how good are our watches. Let’s put some positive here.

My commentary is not to denegrate any watch.
In fact it is like that in most technology.
You are right, I know our watches are good, what I wanted to know, is what the S9B has better than the A3P in order to people make the switch and still have deal with resets and stuff.
I don’t believe that if the watch wasn’t that good, people wouldn’t get back to A3P for example…

@André-Faria have you try it? Do you know all the people who had done the switch or just the bias of go back to the A3?

In this forum, most of the users of Suunto watches don’t come here to say “Ey guys, I love my watch”.

The A3 is a great watch, but just a watch, like others.

Maybe I am getting misunderstand…I am asking…not making a statement…
I never tried a S9B…and I am curious about it…

Hello Bulkan,
Maybe I am not expressing myself well.
I am curious in a good way about S9B…when I posted this was to know more…so maybe I buy it…

@André-Faria You may not find a convenient summary but read @Brad_Olwin’s longer posts comparing the two (DIY search) if you want a largely happy A3P->S9B* adopter view.

Depends on how you might feel about color touch-screens, Suunto Apps vs SuuntoPlus, structured/complex intervals, crowflight waypoints vs exact route navigation, vibration, looped menus and probably lots more, distributed over the forum.

Also, S9 development doesn’t appear to be done yet. With DigiTrans, it’s hard to see the A3P’s future as anything other than a fairly imminent decline in functionality.

*Apparently there was also a Spartan dalliance but we don’t need to talk about that.

Heloo

can gps find you in some closed space (apartment house tunnel

[piko88]

@piko88

and which is the best gps signal to use

Thanks

In general, no.

sometimes GPS is losing you even outdoors in the middle of an activity

That is right, experienced this once so far. I mean every now and then it gets off a little bit for a moment, but just this once it was bananas

Here is a comparison from my long run through Mohican State Park in Ohio. Ambit3 Peak is in orange, Suunto 9 in green using GPS + BeiDou based on my pre-run recon using Trimble GNSS Planning. The two are of comparable quality IMO (you can see the dotted trail peaking out a bit on both tracks in places). The MTB trail I ran is tree covered throughout. Weather conditions represented by additional photo.

[sky-runner]

@fazel How did distances compare between A3P and S9B?

[freeheeler]

@fazel
@kabzior
yes, in rare situations it is off “a bit”… but I’ve never seen the watch taking a nap in the middle of an activity, like mine did

[fazel]

@sky-runner well, I had the 9 connected to a Stryd so not apples-to-apples. 38.57 km for the 9 and 37.14 km for the Ambit. The trail is officially 24 miles (38.6km) long, so the Stryd performed excellent. I know from experience riding it on the MTB that GPS always measures low.

[Dimitrios Kanellopoulos]

@fazel you can see the distance without stryd for pure GPS points (also ommiting the fused speed that the watch applies ) if you like on QS

[fazel]

@dimitrios-kanellopoulos oh - cool. How do I do this?

[Dimitrios Kanellopoulos]

@fazel on the “detail statistics” look for GNSS distance. That is the distance of point to point calculated via the Vincenty method. Its not perfect and sometimes not better than the watch does.

However: You are comparing apples to bananas if you compare GNSS distance vs Distance. That is because you can have a tunnel for example or a difficult GPS terrain were the watch might draw a straight line , and you were actually ie traversing or a tunnel with turns. Consider a snake tunnel and using stryd. Exit to entry distance would be smaller than stryd. And your watch has similar algos with Stryd when GPS is lost or for instant speed etc. Its called fused speed. The watch can without GPS give you a very good distance estimate. That GNSS distance statistic would not.

So I would compare GNSS distance of Ambit vs S9 GNSS distance to see what their GPS recorded approximately.

[fazel]

@dimitrios-kanellopoulos awesome. @sky-runner here’s what I see, GNSS to GNSS.

9 Baro: 38.15 km
Ambit3: 37.23 km

[freeheeler]

@fazel
and these are awesome numbers! …in many ways!
