The problem for the teams isn’t necessarily finding the party, we’ve had these beacons for years. Rather they have to climb into the mountains in the first place to solve what could have, ostensibly, been readily prevented.
Thus taxing a limited resource even further.
What should temper that is now there perhaps may be signs posted telling folks about the service, and that help is available (or not) but it’s likely going to be rather expensive if they have to come get you. It’s never been suggested that while the S&R teams maybe volunteer, as I understand the rescued party incurs costs of the operation.
Usually it's the ambulance / helicopter ride. But even then, there are helicopter operators (like the U.S. military, which responds to many SAR calls where I live) that don't charge.
I don't have data to support this, but I guess that at least 40% of Americans would agree with the statement, "I take cost into consideration when I make a call to emergency services."
You'll get the local 911 response units, and it might be a Sheriff's deputy, fire, or EMS.
If you're in California you're also likely to get a rescue helicopter operated by CHP, and if they pluck you out of a ravine, the bill is $zero. Really, it's taxpayer funded. We operate with them quite often.
Rather, my concern is with the volume. Lots of "I'm Cold, Please Help" calls could take resources away from rarer but far more resource-intensive "My leg is broken, and I"m 10 miles out" calls.
