iPod sent (dark) video for about 1.75 hours from inside the closed freezer then went offline due to low battery. Non-contact IR thermometer reading was 41-degrees for the iPod's face. Recharged it, then put it in sleep mode and back into the freezer in a sealed plastic sandwich bag. Freezer is set for zero. Will check it again in the morning and see if it powers on at or near zero. This is a good test for the worst conditions inside a boat (or a car for that matter) in winter.
