I've flown (behind) into trees twice early on because I thought I was closer than I was. It made me realize I was further out than I thought, and made me consciously think about how far out it might actually be.
This could also apply to a plane that has crashed into a non-visible area like an Indiana corn field. (don't ask me how I know about this).

If you think you have an idea how far out it is..... go out further. It is usually further out than expected. I was out with just my son and I crashed. We looked for an hour in corn over our heads. He had to leave... I went out on my own and found it in 15 minutes. I simply went over in my mind the direction it went down. I followed that straight out into the corn about 100 yards. This is about the distance my son and I stopped on the first search. I kept my same straight out line but went out about 50 yard further, kept moving the sticks, and heard my "wounded" bird rattling the control surfaces!!
The 2 tips mentioned... moving the sticks and going out further was told to me about a week before and boy did it help me!!! ..lownslo..
