i normally swim with my Apple Watch, I do 100 lengths of a 25m pool, it counts the lengths perfectly, every time.
Ive been wearing my newish Fenix Pro last few days to start looking at sleep and hrv data so tried it for the first time in the pool just there. I set the pool length to 25m and did my usual swim, front crawl throughout, no tumble turns.
I could see it was going wrong on distance so counted lengths manually and checked on swim time which is usually within a few seconds of the hour, so 100 lengths, 2500m. Garmin connect says 3775m, which is clearly way over.
Any ideas before it hours in the drawer in favour of my Apple Watch ?
Strange. I use a basic Forerunner 55 to record swimming training sessions and it's almost always 100% correct for distance. That's masters training, up to 3 sessions a week, all strokes, tumble turns etc. Only thing it doesn't do well is record kick - not surprising given the watch is on my wrist.
What's the recording interval? That (IME) has been the major cause of inaccuracy in most sports tracking devices.
Also, apple might be using internal sensors to detect change of direction, garmin (i think) defaults to GPS, which doesn't work so well under a tin roof.
Hmm, I wonder if I have something set wrong, the only option I can seem to change is pool length, which I have at 25m. Recording interval ? Not really sure what that means ?
didn't know it used gps, I’m in an outdoor pool, so should have a signal, either way, it seems to think the pool is much longer than the 25m it is, or something else it making it overread the metres.
It's to save memory, some fields only record a data point every three seconds, or if there is a change,
Ah, gotcha. A 25m length takes me a bit over 30 seconds, so would have thought it would be ok at that.
Not sure if mine's using GPS or internal sensors, but I suspect internal sensors - if it was GPS then it'd record my lengths of kick. Neither can I find anything in settings about recording interval.
@iainc, there's an option below Pool Size in my settings for 'Stroke Detection'. Not sure what the default is, but mine's switched on. Worth checking?

just had a look, was on, have also enabled auto rest and countdown start and will give it another go on Wednesday
Hmm, had a bit of a google, seems to be a common issue with this model
Think will just revert to my Apple Watch, anyone want to buy an Epix Pro Gen 2 Sapphire, in white ? Bought new last June and barely used, perfect condition?
That wasn’t a stealth ad, however I have now put it in the classifieds. I use bar mounted Garmins on road and gravel bikes, an 840 and a 1040, so I don’t use the Epix to record rides and if it’s not going to cut the mustard on swims then I really don’t have much use for it, given I have a series 10 apple watch for daily use.
was probably an impulse PSA buy tbh 🙄
Hmmm, my Epix (GEN2) seems to get it bang on, it's recording as "pool swim", you've not selected some outdoor variation have you? It's not AFAIK using any GPS and doesn't generate a path in Strava.
At worst it's out by a length, very occasionally two in 40. And it's usually because I've stopped and faffed so it's probably just thinking I've been moving for that time and therefore must sill be doing a lap every ~40seconds.
Thanks, no, definitely on pool swim. The garmin forums seem to have a lot of examples, the over counting can be reduced by very precise swim techniques, which I clearly don’t have.
The Apple Watch is less fussy for slowish swimmers like me it seems.
Understood you’ve put it up for sale, but did you have auto rest enabled ?
I’ve used two epix’s mostly for swimming and they have consistently tracked super accurately across many different length pools, mostly inside but some outside. The pro even tracked my recovery super slow awful swim the other week which surprised me, as I didn’t expect it to.
but did you have auto rest enabled ?
no, it was switched off, I think I read that having it off reduces chances of overcounting distance?

my experience and it might just be me, is the auto rest feature positively impacts accuracy. I have it always set on for swims and the Epix never misses a beat tracking swim length, I frequently switch stroke and it records that very well too. I’m super impressed with it.
Thanks, will have another go with it on, unless someone buys it before Wednesday 😁
I just started using mine (Epix 2) and it massively over-reads. Going to try the suggestions in this thread. Although a calendar or sundial would probably be sufficient to track my swimming:)
^^ worth a look on the Garmin forums I linked to, there are a few threads, unfortunately they all say pretty much the same. TLDR, use an Apple Watch if you want simple accuracy without thinking about your stroke and glide 🤪
