Disappointed with Jacket Mode – Missing Key Data from HRM with Running Dynamics

I’m quite disappointed with how poorly Jacket Mode works. I primarily wanted to use my HRM with running dynamics, but I discovered that several key metrics don’t work in this mode: distance doesn’t register, power is unavailable, and vertical metrics are missing.

I’ve tested the regular mode, but I noticed that heart rate data disappears when the watch isn’t worn—for example, when it’s placed in front of me on a treadmill. I prefer to have the watch in front of me while running on a treadmill since it’s easier to monitor my data that way.

How can I get all the data from my HRM (including distance) while having the watch placed in front of me during treadmill runs? Any solutions or workarounds would be greatly appreciated.

    Which watch and HRM model?
    I was using my Fenix 7 with HMR-PRO for outside and treadmill runs, with Jacket Mode enabled and never had problems with data.
    Now I'm doing the same on Descent MK3 and HRM-PRO+ and again, no issues.

    One thing, watch is always on my wrist.

    I am using Garmin HRM-run (that with a red color) and Epix 2. It also work perfectly for me, when the watch is one my wrist.

    What are your settings for the HRM , Pace and distance?

    And dynamic source switching setting?

    Are you sure the HRM is staying connected? 

    Why do you have to use jacket mode? Have you tried it normally with dynamic source switching off?

    My FR965 continues to show HR form HRM when it is off my wrist.

    I just tried it on my 965.

    I put on my HRM Pro

    I took watch off and lay on desk I started a treadmill activity.

    I ran around the apartment a few times

    I got all the metrics fine incl the RD and HR, pace etc

    I have no jacket mode on FR965

    Dynamic source switching is off

    My HRM is set as Pace and Distance indoor only

    Alos try unpair and re-pair your HRM , there was a FW change recently which affected the type of connections due to soem legal regulations. Ive seen a few reports of items not connecting properly,

    There is really something not right.
    I've just checked my girlfriend stats from couple last runs and ground contact balance is missing, all other stats are there.
    She uses Descent MK3i with HRM-Run.

    And it is for both, indoor and outdoor runs.
