When I performed outdoors in the Florida Keys, I always insisted on either a three sided tent/canopy. If they could not provide it, I refused to do the job. Oh, and it must be a dark color. White tents/canopies allowed too much light and made it nearly impossible to see the screen/display.
The only other options were to bring a large, black, beach umbrella, or construct black cardboard hood that shades the screen. However, the hood does nothing for seeing the button lights.
Good luck,
Gary
