This is part two of a two part event. The complete event has a three hour time limit.
The first part on a different map has 8 controls which have to be taken in order choosing your own route.
After completing part one, this map at a different scale is provided and the remaining objective
is to locate as many controls as possible in whatever time remains of the overall three hours.
Each control visited (including the first eight) scores 10 points.
There is a penalty for each minute (or part minute) taken over the allocated three hours.
1 point per minute for the first 5 minutes then 2 points per minute for the next 5 minutes etc.
