Moisture in my 3x9 Bushnell Banner Scope

I was hunting Elk in Colorado this year and had it rain several times and found that my scope fogged up and couldn't complete the hunt. Now I see that there is moisture in the scope. Is this scope repairable or do I discard it and purchase another?

Note Here is Bushnells contact information if you would like to ask them for suggested methods

Note most scope manufacturers offer a mail in repair service, this has to be cheaper than discarding your scope and buying a new one :)

In the past, I have successfully dried out scopes and binoculars by them in a warm oven.NO MORE than 150 degrees and monitor them closely.Many plastic parts will melt at high temps and then you have an expensive paperweight.I have dried out my Pentax 12x50s ($300) several times.I should know enough to come in out of the rain but will probably never learn.Good Luck!

I would say the gas in the scope has leaked out. You probably have a bad seal in it. Send it back to the manufacturer and they will warranty it. All scope companies have really good warranties. TP

Rifle scope fogging

You can try to clear this your self. You will need a good sized clear plastic bag, say kitchen trashed can size. You will need to get your hands on some nitrogen or you can also use carbon dioxide. You will need some good electrical contact grease or Vaseline will also work. Take the focus lens off your scope, let it dry out. Now ck for any o-rings and try to find new if you can, put the grease on the screw threads.Put all the scope parts in the bag and pump up the bag with your nitrogen and tie off the bag but leave room so you can screw the lens back on once it has set for a little bit in the gas. This should let gas stay inside the scope so no moisture can get back inside to fog it up. Try that, sounds crazy but it will work.

My bushnel is fogging up in side of scope it is a banner 3-9x40 what to do?

if the scope is fogging up its leaking water into it, witch means its lost the "o" rings that seal this scope, dont try to fix it as it needs a full strip down and all the glass cleand then a re-seal and a re-gas,
to be honest all you could do it leave it in a warm place to dry out but as soon as you go out with the scope in the cold air it will frost up on you it may be a lot cheaper to just buy a new scope

Scope fogged up on the inside and i cant see out of it. while hunting in the winter the scope fogged up. now that it is getting warm out it cleared up.

The gas inside the scope has leaked out. Moisture condenses in the cold weather and fogs up your optics when this happens. Send the scope to the manufacturer and they will warranty it. All scope manufacturers have real good competitive warranties. TP

Bushnell Banner .22 scope with loose part inside.

It would be better to replace the minute you disassemble a scope unless resealed with special equipment it will never function as well nor will it be reliable and for a bushnell by time you payed for shipping to and from a repair place you'd be at cost of new so might as get new one which has newer glass types that are vastly better than 20 yrs ago
