Pros / The Nikon ACULON T11 is both a high- and low-powered pair of binoculars, with four magnifications to choose from.

Cons / Many of our survey participants were confused about the zoom and focus features and needed more instruction.

 Verdict / The Nikon ACULON T11 is good for beginners who aren't sure which magnification is best for their needs, but it lacks the durability and crystal-clear images of the best binoculars.

The Nikon ACULON T11 offers good optical quality, and images usually appear crisp and clean through its lenses. In our tests, though, many participants found them hard to adjust and focus, and some found that images weren't very clear.

The magnification options on this set of binoculars is unique. You can choose 8x, 12x, 16x or 24x magnification. This zoom function provides versatility, as you can use the 8x magnification for outdoor activities like sports and boating, and switch to the higher magnifications for viewing landscapes and long ranges when hunting.

This pair of binoculars has the smallest objective lenses at 25 millimeters, so it's best used in well-lit areas. It uses BAK-4 prisms, which direct more light toward your eyes, producing higher-quality images than you get with prisms made out of other materials. The lenses are also multicoated, which makes images clearer by allowing more light to pass through them.

Although these binoculars have a central focusing knob to allow you to focus both lenses at the same time, our survey participants found them hard to focus. Many participants also confused the zoom feature, which changes the magnification, with the focus feature, so these functions are not very intuitive.

These binoculars aren't waterproof. This means water could leak into the housing and permanently damage the optics if you use them in wet conditions. The Nikon ACULON T11 isn't fogproof either, so you could experience blurry images when looking through it in cloudy conditions.

At 10.8 ounces, the Nikon ACULON T11 is the lightest pair of binoculars we reviewed. The lighter weight is a good feature, as you can't use these binoculars with a tripod. Still, with the ability to use these binoculars with a high 24x magnification, you might miss the stabilizing effect of using a tripod.

Like the other binocular manufacturers we reviewed, Nikon offers a limited lifetime warranty that protects you from defects in material and workmanship. If you need to contact the company, you can reach it by phone. You can also email Nikon, but you need to create a free online account first. The Nikon support page for the United States doesn't offer live chat support. To access live chat and ask questions directly, you can change your country setting to the United Kingdom.

The Nikon ACULON T11 is a good pair of beginner birdwatching or hunting binoculars, as it allows you to test different magnification settings and have a set of both low- and high-powered binoculars. The very light weight of just 10.2 ounces allows you to use the binoculars for longer without your arms becoming tired. Many of our survey participants did find the zoom and the focus feature confusing, so there might be a learning curve in using them.
