Odp: [Nature Recordists] Keeping recording system warm in cold temps

["Krystian Zwolinski" krystianzwolinski]

Hello,

Maybe try to use chemical warmers. I've never used it but I think, that
it should keep the "high" temperature for some time, especially if You
make some isolation for the tupperware box.
