Binoculars and monoculars

There are hundreds of binoculars across very different price points and uses, so choosing can feel overwhelming. Our team of astronomers and nature lovers can help you find the right pair for your needs and budget. Browse by use below, try a few pairs side by side in our Brisbane showroom, or give us a call.

How to choose binoculars

What do the numbers mean?

In 8x42 or 10x50, the first number is the magnification and the second is the objective lens diameter in millimetres. Zoom binoculars show a range, such as 10-30x50. Bigger lenses gather more light for a brighter view at dawn, dusk or night, but are heavier. For handheld use, 42 mm is a popular balance of brightness and portability. Most modern binoculars are also waterproof and fogproof.

General purpose binoculars

Great all-rounders for travel, sport, nature walks and everyday use. Choose a compact pair for your bag, a waterproof pair for the outdoors, or a full-sized pair for the brightest view.

Birding binoculars

Sharp, bright optics with a wide field of view and close focus, so you can follow birds in flight and pick out fine detail in feathers. Lightweight models are comfortable to carry all day.

Large and heavy duty binoculars

High magnification and big objective lenses for long-range viewing and low light. Most are best used on a tripod, which keeps the view steady and comfortable.

Astronomy binoculars

Binoculars are a great way to explore the night sky. Large apertures gather the light you need for star clusters, the Moon and the Milky Way, and tripod adapters keep the view steady.

Marine binoculars
Waterproof 7x50 marine binoculars

Built for life on the water. Most marine binoculars are 7x because the lower magnification keeps the view steadier and wider on a moving boat. A 10x gives more reach from the shore or in calmer water.

Zoom binoculars

Change the magnification to suit what you are looking at: start wide to find your subject, then zoom in for detail. Higher zoom settings work best on a tripod.

Monoculars

A compact, single-eye alternative to binoculars that fits in a pocket. Some include smartphone adapters for photos and video, making them handy for travel, hiking and wildlife.
