HRM accuracy

Hi,

I have just compared the HRM data to my previous iWatch, and while playing table tennis, the Swim2 watch indicated a HR of 158! While the iWatch measured a more realistic 88. The Swim2 watch was then worn by my opponent, who also recorded HR of over 160BPM!

Anyone else got wildly increased HR readings? Should I be contacting Grmin directly to see if this watch may be defective?

PG, No. What I mean that as soon as I activate 'Cardio' workout, I see the Timer field at the top, and the current HR at the bottom, which is refreshed quite often. What I see is that by simply looking…

I too have noticed inaccuracy in the measurement of heart rate especially when you are at the beginning of a workout, but after it seems that the measurement of heart rate becomes more reliable. I made a comparison during a workout with my garmin Edge 810, the Swim 2 initially measures beats far above the real ones, after a few kilometers, however it starts to be reliable and HRM are the same as those measured from the Edge 810. Anyway I think it needs a solution on this issue because the avarege heart rate is distorted

Running and Swimming HR seems to be spot on for me . . . BUT . . . Outdoor Cardio with GPS engaged gave a wildly high HR. When I turned off the Cardio workout, the background HR immediately was correct. So . . . Something ODD about Cardio gives inaccurate HR reads?

I have no issues with cardio HR. Yes, sometimes it shows weird values for a while, but it is mostly very reliable for me.

This has been a constant problem with my Swim-2. If I use it in cardio mode while riding a bike with a Polar H10 and chest strap it tracks with the Polar. But in the pool it goes nuts. I have a condition called Chronotropic Incompetence and I have a max HR of around 125. In the pool for the whole 1 1/2 hour masters workout it records over 130, even on the rest intervals. It's like it's counting extra beats. I have tried everything including having it very tight on my wrist.

It does keep track of my laps pretty well except for kicking sets and 75 meter lengths.

Guys can you tell me which is the latest stable firmware version? Thanks so much. also can I receive it with the mobile application or do I have to attach it to the computer to receive the latest update?

I got my Swim2 just the other day and it's doing exactly what you're saying! Bizarrely, my Fitbit Charge 4 also recorded higher heart rates for a logged activity than the exact same activity when not logging... Weird!
