I hear you; good point.

Here's where I'm coming from: I'm trying to come up with some priorities, just things to think about in advance for common wilderness survival/emergency situations. The idea behind putting electronic signalling so high on the list is that it's so fast.

TAKE THE FOLLOWING SCENARIO:
Let's say someone in my group falls and breaks a leg on a hike and it's hot out (90's - 100's). First thing I want to do is to check out if there is anything I need to do immediately (stop bleeding, immobilize head to prevent spinal injury, etc.). Second thing I want to do is STOP, take a deep breath, and start thinking/planning. Third thing I want to do is make a call (or activate the PLB) which only takes a minute or two whereas finding shade/erecting a shelter can take time. That's why my 1, 2, and 3 are what they are.

Given an injury, shade/shelter makes a lot of sense as next on the list.

In an environment similar to the one described above, but absent an injury, I might want to move to a place where I could get water, and then do the shelter/shade thing.

The situation dictates the response a lot more than any list will, which is why I've got STOP only second to immediate medical emergency.
