  1. Hi In the UK you don't always have to have the actual OS map because the OS web site has a Get-a-Map button which enables you to find a 1km square centred on the SW corner of the 6 figure part of the Cache reference. Once you get there, you are at the SW corner of a 100m square, you can then estimate the amount of Northing and Easting to get to the SW corner of the 8 figure reference (a 10m square). A Silva Romer helps with this but you have to make sure you have printed the map at 100%, to do that save it as a jpeg insert it in to something like Word or a picture editor which has ruler guides and shrink it to 7.5cm across.
