Freezer Safe, minding the box

Here’s a useful and inexpensive gadget that was just introduced by the good folks at SetSail.com. Just a little bigger than a pack of gum, it will apparently “record and store high and low temperature for 100 days, 100 hours, or 100 minutes”, thus helping a boater “optimize box temperature for best trade-off in food longevity vs. temperature” (not to mention power consumption).
