Field glasses
arena® D+ 10 x 50
Art. Nr. 4254150
Powerful starter model for an unspoilt far view of nature.
Product Properties
- High image quality thanks to top quality BaK-4 prisms.
- Exceptionally bright due to a 50 mm diameter lens and additional silvering of the prisms thereby increases their light transmitting capacity.
- Eye-friendly observation since the silvering coincidentally reduces harmful UV radiation .
- Absolutely watertight and thus suitable for any kind of weather.
- Nitrogen filling prevents misting of the internal optics if the temperature fluctuates.
- Spectacle eyepieces afford an optimal field of view even when wearing (sun) glasses.
- Stable tripod thread ensures shake-free viewing pleasure at all times.
- Accessories: Comfortable carrying strap, bag, protective dust caps.
