How cool is your boat's frig?

Jun 12, 2007
Ever wondered how cold your boat’s frig or freezer gets? Who hasn’t? Is the frig too cold and is it freezing items, or is it too warm and not getting items cool enough? Now you can lay those fears and concerns to rest with a nifty gadget from SetSail.com called Freezer Safe. No bigger than a large stick of gum, you put Freezer Safe in your frig and it will not only give you the instantaneous reading, but will track temps using a built-in graphing section of its LCD screen. You can track date, time, high and low temperatures for 100 days, 100 hours or 100 minutes.

You can also use it to monitor temps in other parts of the boat as well, such as your engine room or your bilge. It will display temps from –5° F to 122° F (-20°C to 50°C). It is powered by two AAA batteries.
