i'm kind of ignorant, but what is "low gun with a hold like one uses for live pidgeon or fitasc"?

i live in BFE, and there is no fitasc around here. i don't even know what fitasc is. the skeet range is powered by a portable gasoline generator. we keep it in the high house. in the summer time we run a long extension cord to run a fan in the clubhouse behind station 4. in the winter time we have some propane space heaters to keep us warm.

is the gun kept at waist level, or ready to be shouldered, or in a semi-shouldered postion?
