Searching in the Dark
You may remember a long while back me writing a short news article introducing a Specialist Night / Low Light Search Technician Certification Course from Gary Foo. Several comments were made at the time, with Jennie Webster making the valid point that; Maybe explicit courses such as this would make it more obvious that ALSAR teams can [...]

Elements of the Optimal Search Problem
Lawrence Stone defined the elements of the optimal search problem in his 1986 book, Theory of Optimal Search. This was paraphrased extremely well by Cooper, Frost and Robe in their 2003 report – Compatibility of Land SAR Procedures with Search Theory as quoted below; A probability density distribution on search object location and state (so [...]

SAR Dictionary
I have decided to start an online SAR dictionary that I will add to every week. Hopefully it will help those looking for more information and/or definitions of various SAR terms. So far I have added; Probability of Area (POA) Probability of Detection (POD) and Probability of Success (POS) More will be added week on week.

Probability of Success (POS)
Probability of Success is the likelihood of finding the misper or search object given the search area and search resource. It is calculated as below; POS = POA x POD It is the role of the Search Management Team to maximise the POS of the search. [Find the missing person or object as quickly as possible!] This [...]

The Use of Mountain Bikes for Search and Rescue
On Friday I posted a news item on the First National Search and Rescue Mountain Bike Instructor Scheme being run by Black Badge. This sparked a debate; on whether it actually was the first but also on the use of mountain bikes for lowland search and rescue. A number of ALSAR Units now run mountain bike [...]
