The Nikon 10x42 Monarch ATB binoculars are lightweight and easy to carry. The Monarch series is targeted toward hunting and birding, but it is also good for general-purpose use.

The Monarch uses a standard roof-prism design that is highly regarded for better light transmission and brighter viewing. Even with this design, the Monarch is relatively small and lightweight, making it a good choice for children. Adults will find that the lightweight design makes focusing and viewing at 10X much easier than with heavier binoculars.

The Nikon 10x42 Monarch features an armored rubber coating that is comfortable and easy to grip. The rubber coating adds to the Monarch's shockproof and waterproof rating, so it's a good choice for use in inclement weather, by the seashore, or when boating.

A smallish eye relief of 15.5mm may be awkward for some individuals who wear glasses. The central focusing wheel is ridged for no-slip control. Full focus requires only 1-1/4 turns to go from infinity to the close focusing distance of 8.2 feet. Ocular adjustment is provided, and the eyepiece that rotates is stiff enough to eliminate any worries about slippage during normal use.

The lens and prisms are fully multi-coated to improve optical performance. The multi-coating helps with apparent brightness and also cuts down on internal reflections that can cause viewing problems. We did, however, notice a very slight blurring at the edges of the field of view, which while sometimes common, was disappointing to find in Nikon's well-regarded optic systems.

Bundled accessories include a case and strap, as well as lens and eyepiece covers. The lens caps rely on the texture of the rubber binocular coating to hold them in place; we found them to be very easy to dislodge. The rubber eyepiece covers, however, were held snugly in place. The strap is a simple affair that serves its purpose, although you may want to replace it with a wider, more comfortable strap.

Through its warranty program, Nikon will repair or replace the binoculars for $10 plus shipping.

The Nikon 10x42 Monarch are good all-around binoculars that can find service with birders, hunters, boaters or just about any outdoor activity.
