Hi Gang
A reminder. The Butterfly polarizer which is an integral part of any LCD display is orientated so that the Butterfly Display can only be viewed in the portrait (vertical) mode if you use polarized sunglasses whereas the portable PowerFlarm display requires a landscape (horizontal) mounting. Why? You figure that out.
My DG1001M came with the 2 Butterfly Displays mounted in the landscape mode so I purchased a pair of articulating arms to mount the Butterfly Displays. These arms can be rotated through at least 180 degrees and fixed the polarizer problems. If I had to do it all again there is no way I would purchase PowerFlarms. Instead for the DG 1001M a couple of MRX PCAS units is so clearly the best solution to collision avoidance. My 2 cents worth after battling the PowerFlarms for more than a couple of years.
