Slightly related to all of this – does anyone know of a meter, or alternative testing method, that works at lower temperatures? My Nano is recommended to only be used above 6 degrees (like the Three Degrees but twice as good?).
I’m comtemplating a three peaks challenge next year and on previous, less well-controlled, long walks I’ve managed to blag it with a pre-walk test and calculations along the way. However, It would be useful to have an accurate guide when around freezing as to where I actually am.
