Suunto SHRB2 Firmware 3.2.6.8 Update

atoponce

@VoiGAS I gave up on it. Got tired of battling it. Unfortunately, I’m outside of the 30-day return policy, so I’m stuck with it. I’ll wait for a firmware update that hopefully addresses it. Maybe I’ll just sell it. Went back to my Polar Verity Sense which has never let me down. I don’t have ZoneSense, but at least I have reliable HR.

@atoponce Polar Verity Sense is just optical, isn’t it?
You won’t get R-R data from that one at all.

as far as I know, all electrical HR chest belts can suffer from ESD, and all deal with it in the same or a similar way. But I am no expert.

That’s true, @egika, but the noise of SHMR2 (speaking for myself) is definitely higher than, e.g. my Polar H10… I therefore wonder how accurate ZS might be as a result of this

My personal workaround was to apply electrical tape over the metal surface on top of the SHRM2 module. I’ve been using it this way, and the performance has been quite stable so far. The only minor inconsistencies occur during sudden pace increases or high-impact movements.! 1000057561.jpg

afaik module’s surface isn’t conductive. Where did you get that information?

Speed Man

@snow I think it might be metal because it looks and feels quite hard.

atoponce

@Egika Yup. Optical armband, so no R-R data and no ZoneSense.

The SHRM2 is significantly worse than my Polar H10. I purchased it because it promised artifact rejection at the module, but I’m seeing a lot more noise.

same merino tshirt (most recent activities were more or less the same)
I wonder if the skin-contact surfaces (polyurethane according to Suunto’s specs) could improve their contact with the skin over repeated use and washing (only rinse it with warm water and no detergent)

Hello my belt is completely discharged in 3 days I had already mentioned the problem which remained active even without the green led am I the only one?

If you haven’t already done so, I recommend performing a factory reset (press and hold the button for 20 seconds until you see a sequence of blue, red, and green led lights. hope it fixes the issue… btw ofc change the battery before trying this!

Hello I think the battery is there for a lot it was covered with sticky products and there seems to be a micro hole on it

it really does seem I’ve finally found the right setup

VoiGAS

@snow Wow, what is your secret?

@VoiGAS the merino wool tshirt and a very light layer of gel (a water-soluble electrolyte solution) covering the entire conductive area of the strap, which means I no longer have to soak the strap completely as I used to. Well to be honest this one was with a 100% poly tshirt

Egika

Crosstrainer. Long sleeve shirt, I spit a little on both contact pads before putting the belt on. No need to soak it or so…

This is the only sensible method. If we had to resort to wardrobe changes or gels regularly there’s a design floor. (Based on two decades of licking so, so many chest straps!)
