[SML] Projector dowser redux

[Keith Arsenault]

i have a 5.5k lumen SANYO . . . one of the features that made this particular projector my choice was the remote shutter built into the unit

the remote works both WIRED and WIRELESS ( wired via a 3.5 mm connector ) 

those two features . . the built in shutter AND the ability to use the remote WIRED ( the booth and the projector are not in a good wireless line ) have been invaluable
