  1. Critical Separation, 2003

    This is an extract from the handbook that accompanies The Centre for Search Research search skills training course. It deals with searcher spacing and critical separation. There is a discussion about searching in different phases of an incident.

  2. Establishing the Search Area, 1998

    The paper considers some misunderstandings in the use of distance travelled data from missing person statistics. By examining the original work done by Syrotuck in the 1970's, the paper develops an alternative method.

  3. Lateral Range Curves, Search Probabilities and Grid Searching, 2008

    This paper explains how an understanding of lateral range curves is a good starting point for understanding the application of search theory to land SAR. Co-authored with David Lovelock

  4. Observations From UK Dog Training Data, 2001

    The assessment of air scenting search dogs in the UK generates a great amount of numerical data. This paper looks at some of the statistics that can be derived from this data.

  5. Searching at night, 2003

    This is an extract from the field skills course run by The Centre for Search Research. It deals with the principles of night vision, suitable lighting and suggested tactics.

  6. Sector Ladder, 2005

    The original Sector Ladder document was published in 1994. This is a re-presentation of the original; the only changes made have been to tidy up the language in places.

  7. The Critical Distance Method, 2008

    This paper describes a procedure that gives land SAR planners the ability to use search theory to estimate grid search PODs, using a value for sweep width that is found by the field team

  8. The critical distance POD curve, 2008

    This is a full page version of the graph for the critical distance method, together with a table of the values on which it is based for users who prefer to use a table of values rather than graph.

  9. Use of Scenarios in Search Management, 2004

    This document discusses the use of scenarios in search management. Note that the PowerPoint slide show that originally accompanied this document is no longer available.
