How do you prevent your HRM Pro from recording false heartrates (200 and beyond) during transport?

I don't want it to mess up my statistics but I already have multiple days in my history with a max heart rate of 220.

The problem is, the HRM Pro activates when it's moving and apparently it can measure fictitious values by just being rolled up in the bag.

Then there is the Fenix 7 that connects to sensors when using glances, being in the app menu or not leaving an activities summary after being done (usually I just hit save and then clean up, talk to people and do stuff until I check back with my watch, but the chest strap is already tugged away).

So later I have this messed up statistics with wrong max heart values before and after my activity.

What is the easiest way to prevent that? Not using the watches features (apps, glances) when traveling with the strap is out of the questions. Unpairing and repairing the strap every time I want to use it or not is also too annoying.

I have to put mine in a Faraday bag. I was having this issue when I walk home, with the HRM in the backpack(wet), after running in Central Park. You can also use a metal box(like a small metal lunch box).

But wont that just sync the data next time? The device is able to store data on it's own.

Currently I'm using a breathable fabric case from an old Casio watch. Strap can dry nicely but also send data.

Easiest way is go to watch menu and disable this sensor when you don't use it.
You don't need to pair it every time after, just need to remember to enable it again before you start new activity.

Still annoying and not a good option (and could easily been overseen) as I stated in my initial post.

Not using a function because it does not work correctly is not a fix.

I think the easiest thing would be some material to wrap around (sind I do that anyway) that prevents it from creating false readings when storing it away.

You were mention unpairing and pairing back, not simple sensor disable in watch menu.
For me it is easiest way to avoid situations you mentioned.

It doesn't record the data when I do this.

Guess I have to find a good compact metal box and remember to take it out when I'm home.

Ideally it would be a soft anti NFC bag, but I only can find wallets or boxes for car keys and nothing that would fit the strap.

Another scenario would be, I have my HRM Pro in the bag because I later want to record an activity with it. But before I just want to record a simple walk without putting the strap on, but it will still be connected because I have it with me, so I have to put it on, or accept completely wrong HR readings (or disconnect it and later forget to reconnect).

Yes this is a known problem. Try using a towel to dry off the contracts thoroughly. The device only activates when there is some electrical conductivity between the contracts.

Also don't use the phone with the Connect software, as this will also connect and sync with the strap providing wrong data.
