Thread: Misting up scopes

  1. #1

    Misting up scopes

    Nothing worse than spotting something , bringing the rifle up, and finding the eye piece is misted up by your breath. Well last night, whilst out with the old night vision, I put one of them disposable, chemical hand warmers just inside the rubber eye piece. Just pulled it out when needed to, and was very surprised how warm it kept the lens. Ok it works out at about 50p a go,but it does keep your spotting hand warm as well.

    I treat mine with 'Rain-x' and have no issues with misting - but don't find my breath affects the glass anyway. Going from an extended stay on the back of the landy to the warmth of the cab is the most common misting problem I see.

    No reason why it should - it's just a hydro-static layer. It's designed for treated glass and I have had no ill effects on my scopes.

    During the 2011/12 winter I found that my work scope was steaming during training to go away. Recently went away to a very hot country and found that sweat was a real problem at steaming up the protective eye wear we use. Sooo... some american friends suggested Cat Crap. Sounds mad, but thats the actual trading name of the product.

    Google it, works a treat, I can see clearly now the steam has gone

    my local B&Q sell it - never thought of using it on my scopes but it was truly awesome on the landy's windscreen. I used the yellow and white bottle ones a cleaner and ones a treatment not sure the cleaner would be suitable for optics though
