Take a proper care of your binoculars or a spotting scope. Buy a cleaning set to maintain your optics. Remove fingerprints, smudges and dust from the lenses and be always sure of a clean image. Are you traveling a lot with your spotting scope? Buy a comfortable field kit. Using your binoculars at dawn or in humid areas? A fog free lens would come in handy. Buy an anti-fog spray from Vortex!
