do all beacons work with each other

Yes, all beacons work with one another, however if you use some beacons like the Pieps, you can tell that different beacons come through with different sounds, because they are each on slightly different frequenciesWhoa, the above is a little off...ALL beacons operate on the EXACT same frequency, that is how they all work together...they transmit and receive on that frequency. The different sounds are just the different characteristics of the pulse rate of each beacon.I've got to add to this.. the pulse rate of the beacons are different, but only the Barryvox Pulse actually measures pulse of av victims (just to clear that up cuz i misread that the first time). Also not all transceivers work internationally because different countries allocate different frequencies for beacons. So a beacon built for Switzerland may or may not work with a beacon built for the US. but within the US all beacons work together, also within the swiss land all beacons work together. But it's easy to check, either make sure the frequencies are the same or just turn them on before you go out, then you have time to return it.
