A free grid reference reader, the size and thickness of a credit card. This product is useful in helping to read more accurately the grid reference of a site. It comes with two scales, the bigger for the 1:25,000 OS maps and the smaller for the 1:50,000 OS maps. To use it just place the reader on relevant 1km square, taking care to align the border of the reader's grid with the blue line of the square - and the exact 6 figure reference becomes obvious. Remember to read the 'east-ing' before the 'north-ings'.

We do not have any in stock at the present, but if there is a demand we may consider getting some more manufactured.
