Actually I am more concerned about how to keep the Transmitter dry in misty wet weather
than warming my hands. Sometimes here in Canada we can be sailing
our boats when a sudden squall will pop up. How to keep my transmitter
dry under those conditions is my main concern.
In Canada we have hand warmers to put in our gloves that work very well.
Shrug off the coldest days with these "pocket furnaces."
Slip warmers into gloves, pockets, hard hats or between layers of clothing.
Shake to use, air-activated. Heats up to 55°C (130°F).
Safe, odorless and disposable.
Heats up to 10 hours.
