How to Choose Binoculars

What do the numbers (specs) on binoculars mean? 

Binocular specs (e.g. 8x42) tell you their strength (the 8) and the diameter of the objective lens, or lens closest to the object you’re observing (the 42, in millimeters). 

Magnification is typically 8, with a wider field of view, or 10, with a closer, more detailed look. A larger objective lens means more entering light and, a therefore, a brighter image. 

What to look for in binoculars if you’re:  

Backpacking and hiking 

• Magnification of 8 or 10 and objective lens diameter less than about 28: (8x25, 10x25, 8x28 or 10x28)

• Water resistant or waterproof

Birding 

• Midsize and full-size models (8x32 and 8x42) binoculars are popular with birders. 

• Magnification of 8 will have a wider field of view. 

• Water resistant and antifog

Whale watching, wildlife viewing, safaris 

• The most popular types are 8x32, 8x42, 10x32 and 10x42. Go with a higher magnification (10 rather than 8) when likely to be far from the animals. 

• Waterproof if whale watching from a boat 

Paddling 

• Higher (10-power) magnification can make steady viewing challenging, so choose 8-power magnification: 8x32 is a popular size. 

• Waterproof model

Stargazing 

• Choose full-size binoculars to maximize magnification and light-gathering ability. 

• Consider 10x42 or 10x50, but know higher magnification options will require a tripod for steadiness.

Is portability a priority? 

• Pocket knives: Space-saving when the blade is not in use. Ideal for hiking, backpacking and everyday tasks. 
• Fixed-blade knives: Stronger, heftier and more comfortable in hand. Weigh more, take up more space and require a sheath for safe carrying. 

Which knife blade shape is best for you?  

Drop-point: Strong and versatile for a wide variety of heavy tasks and general knife work. 

Clip-point: Ideal for puncturing and detailed work, but not as strong as drop-point blades. 

Tanto: Extra strength for prying, scraping and piercing tough materials. 

Needle-point and spear-point: Ideal for survival situations, puncturing and throwing. 

Sheepsfoot and Santuko: Ideal for food preparation, like cutting, chopping and slicing. 

Choosing a multi-tool 

• Consider which activities you do where a multi-tool might be useful. Some multi-tools activity-specific gadgets, like a bit for adjusting bike disc brakes.  

• Common implements include one or more blades, standard and Phillips screwdrivers, scissors, wire cutter, saw, file, bottle opener and can opener.  

• Multi-tools come in small keychain-friendly and pocket sizes for backpacking and other activities where weight matters. Larger tools are for car camping.
