Can you please tell me the dimensions of this case? And can you confirm it is waterproof and can uphold and protect in extreme cold and excruciating winds? Thank you kindly.

I don’t have the inside dimensions for the case, but it’s designed to be used exclusively with the LogTag standard loggers which are 86mm x 54.5mm x 8.6mm (3.39” x 2.14” x 0.33”). The case itself is rated IP67 which means it’s dust tight and will protect against the effects of immersion from 15cm to 1 meter for up to 30 minutes. It’s not designed to be submerged long term.
