@fleshymutant @Brad_Olwin My problems with the Suunto belts were history once i started to clean them as described here.

Basically, after each excercise you put the belt in a sink, fill the sink with warm water while washing your hands and let the belt soak for a while. Rinse it off and let it dry.

Cleaning the belt in the washing machine worns it out. Killed one in roughly six month doing this…

This is absolutely true.
I leave it overnight in a small bucket with 2 drops of dish washing detergent and just leave it to dry when I wake up.
Washing in the washing machine has mixed results due to stronger detergent and potential use of softener.

Somehow I am happy to hear this article has contributed finally.

I agree cleaning them works but…i noticed that the new belt had a much stronger snap connection to the sensor. I think that removing and snapping the sensor in many times can loosen the snap connectors. No matter how I washed mine it wasn’t working well. The new belt is flawless so I think the belts do wear out as well. I put a lot of hours on mine.

@brad_olwin are we supposed to remove the connector after each move?
Does it use energy when connected?

From my observation it can but not always. For that I always remove it when I remember todo so

I’m confused. New belt? Is there any new Suunto Smart Sensor?

[Brad_Olwin]

@yannis-belouris I remove it to wash the belt. But I have heard it can use some energy when connected.

@suzzlo

A “new belt” is just after purchase

you can buy it separately

No, the sensor is the same, but I replace my belt every 9 months on average, they just don’t last more than that for me.

@Frédéric-Fiandino @brad_olwin ahhh men… I’m a bit slow today…
Thanks!

Hello, I am writing through the translator googel, sorry for mistakes. I bought Suunto 9 with the hope that the problem with the HR sensor will disappear. Unfortunately, the problem still exists. I replaced the elastic strap with a new one, I used it for 7 days and now erroneous readings have appeared during running. The heart rate jumps as if it’s twisted. Tomorrow I am sending the HR sensor to Suunto with the complaint. We’ll see what they’ll do. I will be using the HR sensor from Decatlon for 30 USD with my new Sunnto 9. I am tired of this situation, I swim in the pool and the lake irritates me that the HR sensor is defective and other sensors do not work while swimming.

Hi Michał: I swim with my 9 and the Suunto Smart sensor and it’s fine, as long as I don’t drive incredibly hard at the beginning of the length (all belts have this problem). I wet the strap before I put it on, as they stretch by ~30% when wet, and just before I start swimming it feels very tight. After that, it’s fine, and I get good, clean HR data. I blogged about it a bit here: https://t.co/KOJhi6CQlb

Regarding the optical sensor, the consensus is that if one is serious about HR data, one uses a chest strap. Optical isn’t good for applications where there’s movement, and the water buffeting the watch with each stroke definitely counts as movement. I really like optical for background monitoring - sleeping, for example, or perhaps hiking - but for everything else I always use a chest strap, or an optical that’s not on my wrist (Wahoo TICKR FIT, or the Schosche (sp?) Rhythm 24, or the Polar OH1, for example).

Smooth swimming!

@Ze-Stuart but your hr looks really funky if it is belt…

It corresponds to when I’m swimming front crawl, which for me is a lot like trying not to drown, and when I’m swimming breast stroke, which is a lot more comfortable. The big gap is when I’ve decided to stop drowning simulations, and take in the view of the pool… Here’s today’s swim, which I think is easier to interpret:

I think the initial drop is the mammalian reflex (drop in HR upon face immersion), and then I swam 6 lengths of crawl, 6 or so of breast stroke, then alternated for the rest of the swim, until the end when I did two of crawl. I was using a PowerBreather snorkel today, so no drowning simulation!

[SlaSh]

@Ze-Stuart below graph is from SA and looks terrible, I don’t see value from Powerbreather when doing breaststroke as breathing is quite easy in that style, but in freestyle it would benefit.

[Brad_Olwin]

@Michał-Muszyński Suunto has acknowledged a software issue with the sensor. I am not having issues but some are. Fix hopefully soon

[Niko Hämäläinen]

Is there a way of telling Spartan Wrist HR to disconnect the Smart Sensor after a workout? Other than unpairing it? Seems like mine stays on for a good while even after unplugging it from the belt and placing the sensor on a table. While the connection is active, the watch refuses to measure HR with the optics. Optimal solution would be to have an option to select which HR sensor to use, or if any.

[Ze Stuart]

@SlaSh that bug is also present in the watch; there’s a thread about it… somewhere!
