Binoculars for Spectator Events
Field of view matters on the field
Low magnifications such as 6–8x work well for most spectator events because they have wide fields of view. Binoculars with higher magnifications have more narrow fields of view. With a wide field of view, you can see more action on the court or stage.
The field of view is the distance seen from left to right when looking through binoculars. This distance is measured in one of two ways: linear feet at a distance of 1000 yards or angular degrees.
Waterproofing for outdoor events
Use a waterproof and fogproof binocular for protection of the optics in any weather. Waterproof binoculars are sealed to prevent moisture, dust, and debris from getting inside the optics. Fogproof binoculars are filled with nitrogen or argon gas to inhibit internal fogging caused by temperature extremes.
