You are looking for the Bonus cache for the Ad Lab in Holbrook, Derbyshire, placed by Sooseeker.
You don't need to attend the Virtual Stage - though you might be ready to at the end!
The Ad Lab is intended to be a short(ish) walk, though the first stage is a little bit further out and may, for some if not all, necessitate some driving to the First Stage and then relocating more centrally to the older part of the village. Though we have given a terrain rating to suit the walk, a wheelchair user may equally be able to access this cache, upon completion of the Ad Lab.
The Bonus Info will be available on completion of each of the stages and then you'll have the required numbers which need to be inputted to fit the following format.
N53 00.ABC W001 2D.EFG
The cache you are looking for is a small, narrow disguised tube, magnetically attached to its host.
We hope you enjoy the Ad Lab, which has been quite some time in the making, due to the location of "Southwood House" now a school, without having to physically get there, as the footpath runs out some 200m away which is the final stage, we have ensured that you can obtain the necessary info, by use of a Multiple Choice answer to get you the final bonus answer from at least that distance.
***Please park considerately for the resident population - there is usually some space somewhere.
Happy Hunting.
