What is a recommended technique for locating footprints in the field?

Utilizing a raking light held close to the ground is an effective technique for locating footprints in the field because it casts shadows that highlight the contours and indentations of the ground where footprints may exist. This method enhances the visibility of subtle changes in texture or elevation, which may otherwise be overlooked in natural lighting conditions. By directing the light at a low angle across the ground, it accentuates details like the edges of a footprint, making them easier to identify.

In contrast, methods like wearing specialized footwear for tracking may enhance a person's ability to navigate but do not directly aid in the detection of footprints. High-held raking lights may not provide the same clarity for ground-level details and focusing on bright colors in the environment does not relate to identifying footprints directly. Thus, using a raking light effectively in close proximity to the ground can significantly enhance tracking efforts by making footprints more visible to searchers.
