How is Average Maximum Detection Range (AMDR) determined?

Average Maximum Detection Range (AMDR) is determined through repeated distance measurements from a clue. This process involves systematically assessing the environment and detecting the maximum distance at which a search team can locate an object, clue, or individual under various conditions. By conducting multiple measurements from the same point of origin in relation to the clue, the team can establish the average distance at which detection is successful.

This method provides quantitative data that takes into account the variability of terrain, visibility, and other environmental factors. The systematic approach ensures the determination of AMDR is rooted in empirical evidence rather than subjective judgments.

In contrast, estimating based on terrain, making calculated guesses, or using GPS equipment might provide insights but lack the precise and validated criteria needed for establishing AMDR. While terrain and technology like GPS can assist in the search process, they do not establish detection capacity directly as repeated measurements do.
