I use to repair/collimate binoculars professionally, but working on all plastic Chinese binoculars always scares me.

The mechanism is a bit complex to describe, but essentially it's a combo focus and lateral displacement for collimation, with a locking ring. Any deliveries scheduled to arrive on the Saturday or Bank Holiday will be delivered the following working day. My pair have excellent views with good collimation, but the focus seems to be skewed to slightly beyond infinity for my eyes. But the fact that the changeover to use them with and without glasses opens up some interest in binoculars with mirrors and prisms. If the weather’s unusually cold, just wrap your camera in a plastic bag that has silica desiccant packets for the reduction of moisture.In fact, with the Bushnell 4x30mm Xtra-Wide compacts, the action is always in frame, and you won't even have to take your hand out of the peanut bag to follow it. Ideal for applications when optimum holding force is required such as hinges, brackets and high load environments.

You can keep an eye on the drummer and the lead guitarist at the same time, see the whole stage at a play, or follow a bullet pass as it rockets down the sideline.

It’s also a smart idea to have a soft towel with you to wipe off any moisture, just in case it should get on your camera.
