Projector Used in Chillian Miner Rescue

This is from the Chile Mining Rescue this last year. A projector was sent down and I took the time to evaluate which one it is below.

There are rumors on Engadget that the projector used was a Samsung Beam. This is obviously not true (or only one of several used) if you look at the video below and this picture of the Samsung Beam. The Beam has the focus wheel on the side not the front.






I apologize for the poor quality/advertisements in this, it was the best one I could find. Look at 36-38 seconds to see the projector used. It was a 3M MPRO 120 or 3M MPRO 150.




@ 24 seconds:
Note the focus wheel










From 3M Website

Note the similar curves of the sides, the focus wheel on the front.
