last year i muffed a shot because i breathed into scope...i followed a deer up and down hills for an hour and caught him side hilling me down low.. it was cold and wet and my breath fogged the scope. i was breathing very heavy and was overheating from the chase. i know bushnell has rainguard and have heard of people putting rain x on there lenses...hate those caps theyre noisy.. anybody this happened to and how did you fix it..my gun doesnt have fixed sights.
