Suunto Vertical Overstating distance

Elipsus

@Zalupas which custom mode did you use for GPS ? on the Vertical, unless you are in “high performance” GPS mode, you won’t have dual band enabled, which is why the signal was bad under trees or gorge.

In “high GPS performance” the battery life is estimated to 65 hours, for a 50km race i don’t understand why you wouldn’t select it ?

RightNow

@Elipsus If he is using the Stryd footpod then the distance is coming from the pod? Right?

Elipsus

@RightNow I never used a Stryd pod so I don’t know ^^
But let’s be honest, the dude didn’t really bother to answer previous questions and just created an account for this post, so I’m pretty sure we won’t hear back from him (I would love to be wrong tho)

@RightNow That is correct unless you tell the watch not to do that.

Zalupas

@maszop nothing strange on the map…

Zalupas

@RightNow could be the issue but I had no issues on shorter runs… I will run my next ultra without Stryd

Zalupas

@Elipsus do you refer to battery mode? I used custom. By high performance you mean the mode performance? I will try performance next time but I think I read that custom is pretty much the same

@Elipsus sorry for not replying early I thought my post never went through as never got a notification it had done it! Then I could not reply until I found out that my email hadn’t been verified so did not know how to answer until a friend of mine explained me why last week… apologies did not want to waste your time guys!

And yeah I will check with no stryd in my next ultra!

Zalupas

@Brad_Olwin how do I tell the watch not to do so as I am interested in seeing my power but don’t want to mess up my distance…. Thank you!

Elipsus

@Zalupas Yes battery modes
You seemed to be on rough terrains, so probably either lot of tree cover or steep mountain sides, which is no bueno for GPS signal as it has a tendency to either get absorbed by trees or bounce on hard vertical surfaces, so the signal get really bad.
Fortunately, the Vertical has dual band GPS, which allows it to use two GPS frequency at the same time, which is great for signal strengh and excellent for challenging environnements.

I don’t know what you customized in your custom mode, so i can’t tell if you had dual band enabled, but i know that the “performance” preset uses dual band, so i would suggest to stick to it unless you go for 200 km ultras.

Side note, the very last update (from a few days ago) did also slightly improve distance calculation

@Elipsus noted! Will try this! Thanks!
