I think that they are pretty worthless in the field. I have them but I use them to keep the dust off in storage. They are too noisy, they catch on brush, they break and if it is raining and you put them down they will fog. I think that while hunting you are better off without them. If you are worried about rain just wipe the rain off every once in awhile, you can still use the scope with rain on the lens but you can't when they are fogged.
