Two HRM's interfering with each other?

Does anyone know if two heart rate monitors that are the same make and model will interfere with each other?

Let's say I'm hiking with a friend and we are both wearing our HRM's. Is it possible that we will pick up on each other's rates or cause interference in any way?

    No. Wrist sensors are obviously in contact with your body or use accelerometers tha respond to movement. Chest strap monitors are coded so they do not interact.

    This could be possible. I study fitness health and exercise. A group of us went out running using HRM's and there was an interference with some individuals HRM's due to use being in close proximity of one another, so yes it is possible.

    Millions of cyclists do group rides every day and millions of runners do their thing in groups, too, most of them using HRMs. This is not a complaint that comes up.

    most a locked (paired) in to particular receiver.
    I've been in spin classes where peope next to me that were not wearing chest strap transmitters saw my heart rate on their bike display. Keiser spin bikes.

    When I first got a Polar HRM 20+ years ago there was some interference. They very quickly started marketing devices that were paired, to avoid it happening.

    I've seen my HRM showing up on the treadmill next to me at the gym, it confused the guy on the treadmill because he wasn't wearing a HRM.

    But if he was wearing a transmitter his tread mill would pick up his because it would be the stronger signal.

    I own a good number of different HRM's and for a vlog a whole back comparing a load of different ones on the same run - I wore around 6, none of them interfered with the other.
    They're encoded. :)

    But, assuming everyone uses ANT+, you can read everyone else's HRM (and cadence, power, etc) if you want to.

    Just for fun, you can stand in a peleton or triathlon transition and search and find hundreds of ANT+ transmitters.

    Now there is a slight chance ( we're talking 1:10^6) that two HR are using the same channel and the head unit would try to read both HR at the same time.

    There was an issue with Polar monitors about 10-15 years ago--when they were one of the few names in the game and were ubiquitous on treadmills and ellipticals... I imagine that technology has come a long way since then, but it's still a possibility, especially at the low end of the price range.

    Can it happen? Yes. Is it going to happen by accident? No. At least not assuming both were properly setup initially.
