It is right that it has no influence on the GPS accuracy

That is specifically what I said in my original comment, with emphasis on GPS accuracy. Yes, it does influence fidelity of the track, but it cannot produce significant inaccuracies like offsetting the track, cutting through houses, etc.

Personally I think that this option should no longer even exist because modern devices have plenty of storage and recording every second is the right choice (that's what I have on my watch). The only purpose it serves is that it probably saves some space on Garmin servers where user data is stored. That's probably why Garmin keeps enabling it by default on all new devices.

So that's fine because we agree. My orignal claim from the page #4, that you reacted to, was as follows. I never claimed the recording mode had an impact on the GPS accuracy. I merely wrote it could improve the path (track) accuracy, and that's true.

BTW, I may be wrong, but it looks like you only use the default "Smart Recording" mode. If you want a more accurate path, enable the "1s Recording".

Not really, it also reduces the CPU processing and the I/O operations, and then the transmission times when syncing to the app, hence slightly reducing the power consumption. That's the main purpose, I bet.

this is on all + multi in my local park on hike. 

however the strange thing is that when I am not in activity I just put the map on , normal map no recording, even in the forest the accuracy is great I’m bang on the lines and paths. It’s a bit slow tho but really good accuracy. At least here locally and on open space. Way better. Can I just buy a watch and that’s it it feels like I’m manufacturing the product

I did not photo the only map accuracy , cannot be bothered anymore with it 

I am sorry to add my own negative experience with the GPS accuracy to the thread. I bought the Enduro 3 solely and exclusively because of the allegedly increased accuracy due to dual band addition to the GPS measurements. 

First thing I tried was a walk to the mail box, all GPS systems plus dual band enabled and it was WORSE than my Enduro 2. Much worse. There are no buildings or trees blocking the view of the sky and I live at 4500' altitude. Even if I screwed up the settings in some way (which I don't think I did, I have owned Garmin devices for 20 years) the readings should be at least as good, not worse. 

I don't care much about shenanigans like estimated VO2max and sleep quality. I want accuracy of actual, measurable data. 

As an aside, the wrist based HRM performance with the Enduro 2 or 3 for me has been abysmal. But that may be just me.

Enduro 3 is going straight back. I am so disappointed that I will probably not ever think about buying Garmin again. The price / performance ratio is way too high. 

submit GPX data with description to support.

Yeah same here .... I wanted to love this watch. I will be testing it soon in the mountains but idk ...

I was been fishing tomorrow and had a litle tests. I was in directly one place (< m^2) and just twitching(periodically turning around to change lure). Mode: Max accuracy. I've run couple of tests about 20min each long.

Mode: Fish (Max accuracy)

Mode: Walk (Max accuracy)

Mode: Fish (Max accuracy + every second recording)

And finaly: the same but I take off the watch and put it on my backpack (not moving all the time)

As we can see that Garmin think I'm moving in all directions while I'm not. So I think it not the hardware issu but software one. I hope they could fix it...
