I see nurses using the tiny battery-powered versions quite a bit now. Sometimes they even have colour-coded cases.

They seem like a great addition to the toolkit and they're so quick to use that they don't get left behind like more complicated tools would.

I've been taught in Sports Injury Management that these are useful but can be off as much as +/- 5%. Just something to keep in mind.
