Binocular Frequently Asked Questions

A: All Tasco binoculars come with a cleaning cloth but we recommend the use of our special Lens-Pen which is specially designed for cleaning camera and binocular lenses. Otherwise use a soft lint free cloth.

Remove any dust or dirt by brushing or blowing with a soft lens brush. Do not use window cleaning solutions as they may damage the lens coatings. Then clean across the lens (not in circles) with your Lens-Pen or cloth. Do not rub hard or you may damage the coatings in time.

Q:  How should I store my binoculars?

A: We recommend that you clean your binoculars and then store them in their case with the Lens Caps OFF. This allows air to circulate around the lens and prevents mildew from building up on the lenses which can happen if any moisture is trapped between the lens and the lens cap. Lens caps are really only needed when your binoculars are outside their case.

Q: When I look through my binoculars one side is sharp but the other side isn't?

A: Because our eyes aren't exactly the same you can (and have to) “set “ your binoculars to suit your eyes. The procedure is quite quick and simple for all binoculars:

1 Close your right eye (or cover the right objective lens) and focus the binocular only using your left eye and the main central focus wheel.

2 Now swap eyes by either closing your left eye or covering the left objective lens (don't forget to uncover the other one) so you are only using your right eye. The right eyepiece is separately adjustable so now adjust the focus by adjusting the right eyepiece without adjusting the central focus control.

3 Your binoculars are now “set” for you. If you look at the right eyepiece on the binocular you will see a “scale”. By noting your setting you will always be able to return quickly to your setting after someone else has used them.

Q: My binoculars have a double-image and I get a head-ache when I use them. Why?

A: Your binoculars are “out of collimation” which means that they have been dropped or knocked hard and the prisms aren't aligned anymore. If you return them to us we can usually fix them for you for a small charge (unless they are covered by our famous “No-Fault Limited Lifetime Warranty” in which case they will be fixed or replaced for free!)
