Frequently Asked Questions

Yes, the 20mm eye relief is very generous, allowing comfortable viewing with glasses on. The twist-up eyecups adjust to accommodate both eyeglass and non-eyeglass users.
They are rated JIS Protection Class 7, which means they can withstand temporary immersion in water up to 1 meter deep for 30 minutes — more than enough for rain, splashes, and wet outdoor conditions.
The close focus distance is 16.4 feet (5 meters), which is adequate for general nature observation but not ideal for very close-range subjects like nearby butterflies or flowers.
The 6x magnification provides a very wide 459-foot field of view, making it easier to locate and track moving subjects like birds. Lower magnification also means a steadier image when hand-holding, with less shake than higher-power binoculars.
