I wanted to use SI units and Autodownload with the Cloostermans ZigZag 3 exercises. Our SI Boxes were numbered 201 upwards.
So, I’ve created a new Master Map, with the SI numbers instead of those on the original. You can download this here.
I have also created an Autodownload file for use with this. I have put a copy of the backup file of this here.
We use this with a projector and live results with the UVHS kids and my NavNight group. It is a bit of a faff to set it all up, but is good fun. It takes reasonably competent orienteers more than 20 minutes to get through all 12!
