There are a few reasons:

3. An imager with a display facing skyward is almost impossible to use outside in daylight...the reflection from the sun is overwhelming on the display.
The rotating handle addresses some of that, but as firefighters should know, hinges are generally weak points and more prone to breaking. The single-body imagers are far more popular for that reason.
Beat to the punch. Out of all the cameras I've used for day to day ops, the T3/T4 series are hard to beat.I DON'T crawl looking at the camera.I take a "snapshot"of the room at three levels,pick a reference point,move to it and do it again.And again.And again. Maintaining reference to the wall so if the camera fails,I still know where I am and where the exits are. T.C.

That is the reason we chose Scott SCBA because of the non swivel back frame plus it is T-69 aluminum and not plastic.
