Congratulations on selecting your new Carson binoculars!

With reasonable care, your binoculars will provide you with years of enjoyment.

In order to achieve optimum performance, please read the instructions

carefully on the proper use and care of your binoculars.

Instructions for Care

Like any fine optical instrument, your binoculars should be 

given sensible care.   Keep the lens covers (not included with 

some models) on the lenses when binoculars are not in use.

Do not drop or violently jar your binoculars.  This may cause the internal 

optical components of your binoculars to become misaligned resulting 

in a double image when looking through them. Non-waterproof models 

should not be exposed to excessive moisture.
