About the Product
Magnification exceeding of equal weight: A convincing feature precisely for the comments from Great Distance. In addition, the 10 x 42 model is always the first choice for a particularly precise observation of detail. The Terra ED 10 x 42 model is available in Black, Black/Grey and Black/Green.
Even with an uncontested heritage of all-conditions optical performance, the all-new MONARCH 5 further elevates its game with improved agility and advanced low light brilliance.

What customers say about "Key Specs"
Zeiss Terra ED 10x42 Binoculars (Black)
  • Great bird watching binos. Just what we needed.
  • The image quality is superb and they are light enough to allow long periods of use without getting tired.
  • Expensive, but these are the best binoculars I’ve ever used.
  • That model is my favourite, quality is perfect
  • I bought these for long range coastal viewing and distance countryside viewing they are good but i suspect that they do like lots of sunshine.
Nikon Monarch 5 (7577) 10x42 Binocular
  • They are very clear and show good color of the birds and butterflies that I like to study and enjoy!
  • The lens cap deal is really a non issue, they were designed that way as others have pointed out. I enthusiastically recommend them!
  • Good light gathering allows for viewing in dim light. Used in light rain with no problem.
  • The Monarch can focus much closer. Even at 10X, the Aculon couldn't focus on anything within about 40'. At 22X it was much worse. The Monarch could focus as close as about 9'
  • Excellent for bird and nature watching. Excellent optical clarity and easy focusing. No complaints.

What customers say about "Features"
Zeiss Terra ED 10x42 Binoculars (Black)
  • That model delivers bright, crisp images, even in low light.
  • The Zeiss Terra ED delivers razor-sharp images of far-away objects.
  • The large focusing wheel provides easy handling and optimum grip. 10/10
  • Images in low light seems bad
Nikon Monarch 5 (7577) 10x42 Binocular
  • Very lightweight - needed a pair of light bino's for my bad neck and when I walk long distances on trails in parks, refuges and wildlife areas.
  • Focus works well. It did take a day or two to get use to using the focus knob quickly on active feeding warblers but thats normal for any new binoculars.
  • Eye relief is great! I wear glasses and I haven't had any strain on my eyes while using these on close or far away objects of interest!
  • They are comfortable to hold. I plan to get a harness because I find it uncomfortable to have anything hanging around my neck, but the strap that comes with them is a really nice one.
  • I like that you can't lose lens covers( see previous sentence ).I have some less expensive Tasco binos and there really is a big difference in quality and features.
