I was wondering if anyone uses those disposable hand warmers that activate when you open the sealed plastic bag and rub the 'charcoal' together.

I know they work Ok, and I can't smell anything coming from them, but wondered if they put out any scent that a deer, or hog could pick up.

By the way, a friend had battery operated warmers for hands and feet, but quit using them after discovering that they emitted a very high pitch that he had to listen very hard to hear.

Thanks,

Randy
