I think the best thing to use is a compass or a GPS. It will guide you right to it. What we do at our club also,is have someone take their plane and fly in the area it was last seen. That usually gets you close to it. The corn around our field get a good 8'+. The first few steps into it and your lost!!

The good news is the corn isnt goin to be there this year!! Just soy!!

Cya..
