Ive dropped more than a few knives in the brush. As long as I can narrow it down to a relatively smallish area, I have a big magnet I tie to a line and just drag it around. Pretty amazing how well it works. Primitive I know but metal detectors are about buried treasure, yours is likely on the surface!
I can just picture that scene. People out walking there dogs saying to each other, whats that strange person doing??? Do you think we should call somebody??? Brilliant:thumbup:
