This is just something extra you have to carry. It does not have to be glass, just shiny metal

I've mentioned this in other discussions, I hold my Phantom during warm up making it really easy to see the LEDs. This method is totally unapproved and not recommended, but it works for me. I hold the Phantom at eye level at a safe distance from my face. Facing the direction I want course lock, the left hand skid rests on my left hand. My right hand is holding the right rear prop arm below the props. Thumb on one side, two fingers on the other side of the arm and two below. The LED is clearly visible holding it this way. It's like cupping the LED in a shadow.
For the first battery of a series at a new location, I push the battery button and hold as still as possible and wait for start-up, warm-up and satellite search. I get the two green sequences and then perform the compass calibration. Then turn off the Phantom, turn on the camera, start recording and then holding the Phantom again at eye level again, push the battery button and watch for a full sequence. Set the Phantom down somewhere I want to be home point, perform control stick combination and fly away.
The second, third, etc, batteries at a location the compass calibration is not needed, but I follow the same holding method each time I power up.
It works for me and I always see the LED sequence. Warm up is so short, it rarely takes any time with a Phantom 2 Non-vision version 1. Quite the opposite, the Phantom 1 version 1 took minutes.
