be systematic... scan your surroundings horizontally a foot at a time (Remember Tommy Lee Jones when he was hunting Wesley Snipes in the movie "The Fugitive"?) Better yet, refresh your memory, you might have remembered where was the last echo you heard that sear spring went. Your disappointment is the one clouding your mind right now. Regulate your breathing... be aware of your breathing... then when you have regained your senses go and grab that flashlight again and start looking. As TJK said, we have faith in you bro'!
