[Model number] CB-020 [About effective diameter] Effective diameter is an index that indicates the ability of binoculars to gather light. The higher this number, the more light can be collected. However, binoculars with a large effective diameter tend to be heavy, so 20-25mm ones are best for general concerts. Furthermore, when observing a dark place rather than a stage, an effective diameter of 30 mm or more is desirable. [About magnification] It is wrong to think that "the higher the magnification, the better you can see." The appropriate magnification will depend on the purpose. In particular, too high a magnification narrows the field of view and darkens it, so it may not be suitable for concerts. The recommended magnification for each venue is listed below. Budokan: 8x arena seats, 10x stand seats, Tokyo Dome: 8x arena seats, 10-12x stand seats, Osaka Dome: 8-10x arena seats, 10x stand seats, Sapporo Dome: 10x arena seats, Tandoori seats 10 to 12 times, Nagoya Dome: arena seats 10 times, stand seats 10 to 12 times, Fukuoka Dome: arena seats 8 times, stand seats 10 times, Saitama Super Arena: arena seats 8 times, stand seats 10 times. Please note that these are just a guideline and the magnification that is more suitable for your field of vision may change. [About weight] Considering long-term use, we recommend binoculars that weigh less than 300g. However, binoculars weighing less than 150g may have problems with the quality of the material or the thickness of the lenses. High-quality, lightweight binoculars usually cost more than 10,000 yen, so be careful when choosing inexpensive lightweight binoculars. Preime binoculars are designed to maximize the enjoyment of live performances. Please enjoy the live performance 100%.
