30-Second Fieldcraft: How to Clean Your Optics

Whether it’s a riflescope or binoculars, clean optics make all the difference when it counts. The following guide explains the best tools, techniques, and habits for keeping your lenses in top condition.

How to clean your optics

Start by removing dust and grit from the surface of the lens and the surrounding area. A blower bulb or soft lens brush should be used for this task, as a cloth may drag fine particles across the glass and damage the lens.

Next, apply a small amount of lens cleaner (water-based, alcohol-free) to a clean microfibre cloth and gently wipe the glass in small circular motions, moving from the centre outward. Never apply cleaning solution directly to the glass. Instead, spray it on your cloth. This will allow the cleaner to spread evenly and lubricate the surface of the glass, preventing scratches while breaking down oils and smudges.

Avoid using compressed air cans, alcohol-based cleaners, tissues, or shirt sleeves. If you’re passionate about hunting, its likely that you’ve invested a significant amount of money on high-end optics. These items should be treated like precision instruments, not a disposable objects.

The NSW State Forest Hunting Ballot

Each year, deer enter their peak breeding season between March and May. During this time, their natural defence mechanisms are relaxed as they focus more of their attention towards finding a mate, and less on self-preservation. This period is commonly known in Australia as the rut, or the roar. As a result of these behavioural changes, deer become easier to hunt, making it a popular time of year for hunters to book into NSW state forests.

If you’re planning a trip during the rut, you’ll need to understand how access works. The three most popular NSW state forests switch from normal bookings to a ballot system. This article breaks down how it works, why it exists, and what you need to know before entering.

Two Classes of Australians: Culture-Based Discrimination and Government Hypocrisy

Politicians claim to place equal value on each of their constituents, regardless of where they come from or who they are. In reality, they pick and choose who to discriminate against, guided by political optics and personal agendas. Their most common targets are hunters, anglers, and law-abiding firearm owners.

In this article, I outline the prevalence of culture-based discrimination in Australia and question why our recreational pursuits are constantly threatened with extinction—despite having deep roots in every corner of our multicultural society.
