With new technology must come caution
As I know, the new guy's opinion means absolutely squat here, as in most places, so I'll try to tread lightly.
Eaglesrule1024 is obviously one of us who seeks to be the best at what we do ( or in my case, did ), by looking for ways to improve on tools, techniques and tactics. More of us should do that. The idea of incorporating a thermal imagine device viewer into the facepiece of an SCBA is simply brilliant, and ( with apologies ) has been around for awhile. We sci-fi fans probably started thinking about it after the film Predator was released. However, at that time, there was not any practical means by which to accomplish it. And, it was put aside, like those flying cars they said we would have in the 21st century ( Still waiting! ).
But, be that as it may, it is a great idea whose time may have, or soon will, come. With enough pushing on the part of the guys (and girls) in the trenches the powers that be will start harping for it and it will happen.
My one concern with the entire premise, however, is something which the military has encountered in the past when adding insturmentation to aircraft, sensory overload. Pilots would spend to much time studying their insturments ( and, who doesn't, I ask you? ) that they would simply forget to look out of the cockpit and fly right into the ground.
I would worry that too many displays in front of a firefighters eyes, particularly one who is stressed, could lead to disorientation, "tunnel vision" or "brain lock". The other problem, which I am sure we have all seen at some time, is overdependence on the technology and atrophy of the skills and techniques used prior to the arrival of the next greatest thing.
Just my two cents and, yeah, you probably owe me some change.
Stay safe and watch eachothers' backs.
