With temps well below zero, time to remind
binocular users to take some simple precautions on these frigid days. Biggest problem in sub-zero weather with a binocular is frosting on the eyepieces caused by condensation of your breath on the eyepieces, which quickly freezes when you lower the binocular away from your face. Try to direct your breath away from the binocular when raised to your face. Keeping the
binocular tucked inside your coat where things are nice and warm and then bringing it out into the cold can also cause problems with condensation. I usually just keep the binocular outside my coat. Lastly, I always carry a zip-lock bag. I put the bino in the bag before I bring it inside the house and wait a half-hour or more for the binocular to come to room temp before removing it from the bag. That way moisture condenses on the outside of the bag, not on the binocular. Stay warm.
