Heart Rate Intermittent

I had the 235 previously and had ok performance for about 2 years. It would be terribly intermittent at times when doing indoor routines eg from treadmill to rower to bike. Predominantly seemed to work better always on the treadmill but on the rower and bike, woeful. I saw the release of the 245 and eventually after some research though this model may be better at HRM. Disappointingly I forked out the money and its the same or at times worse than the 235. At max effort the HR just sits around 90-100 or at best 130 and doesn't move much. For the price of the watch and the age of the technology I think this is very poor. This is a specialist watch that Garmin make for this sole purpose and it doesn't cut it. Due to the intermittent nature I don't know if it's software or hardware. Maybe Garmin needs to go and talk to Apple. My old apple watch series 2 has no such issues and if it wasn't for Apple's crap interface and recording I'd go with them instead. Very disappointing.

    It's a day-1 issue. See topic 'hr accuracy issues', but I dont think anyone from garmin wants to acknowledge or provide more insight.

    I think it's a software bug.  Optical HR works relatively well for Run's, but is flakey for any other type of custom (indoor) workout.

    At some point I got a replacement watch, and the issue is persistent.

    I went for a ride last week and used the watch to broadcast my heart rate to my edge 530. My heart rate barely got above 90 bpm which I didn't think could be correct. Today I wore my chest strap for the edge (which showed an average of 118 and a max of 171) and wore my watch but didn't do anything with it. The watch picked up a max of 118 (I don't know what the average was as move IQ only picked up 20 minutes of the 2 hours). I don't understand why it doesn't work unless you are running or walking? I know it is a running watch but to be quite so wrong...

    My 245's heart rate monitor worked flawlessly since I got it (mid-June). The day the 3.1.0.0 update rolled out, I now have terrible heart rate tracking issues. It drops to the 40-60bpm range halfway through my runs, consistently. I wish I could roll back to 3.0.0.0, but I can't find a way to do that. Does anyone know if it's possible to roll back?

    The first recommendation we would have for anyone experiencing inaccurate HR readings would be a hard reset (holding power button down approximately 15 seconds until display is off). This would mostly apply to users who have seen a change recently or after an update. 

    To address general complaints, our optical heart rate sensor will have a more difficult time getting accurate readings during activities with significantly more wrist flexing. This would include activities like strength training, rowing, boxing, etc. 

    We offer the ability to pair an external HR strap for users who want the highest level of accuracy. All of the variables that can alter optical heart rate readings will be different for each user.

    unfortunately none of that works. I'm fairly confident it's just a software problem that only occurs after X min in a non-running activity. The bad readings persist even when in a seated position.  It's like it has a training algorithm that just went bad.

    You could basically proof the issue by using a non-running workout and do any type of sport, including running. (and keep the watch stable, no wrist flexing whatsoever!)

    And if I were the only person with the problem, then yeah... then I was probably not doing something right. There are just so many people reporting this buggy behavior. Mostly 245 series, few 45.  Haven't seen much of this on 945. I don't have the money to upgrade to a 945 (I wish).

    This is not just about 'highest level of accuracy' , the readings are just way off the chart, and stay off, they don't normalize after a period of time, it never 'catches up' like you'd see when running and doing intervals (where the optical HR needs a bit of time to catch up - and I find that perfectly acceptable)
