The easily exchangeable metal eyecups have 4 clearly defined levels. For cleaning, the eyecups can be unscrewed counterclockwise and removed.
Non-slip focusing wheel
The focus point can be set perfectly, not too easily and not too stiffly. The adjustment path is deliberately chosen to be slightly wider so that the absolute visual acuity can always be set successfully.
The housing of the HDs series is made of aluminium, so the binoculars survive a fall from a great height unscathed. The newly developed armouring allows the binoculars of the HDs series to "stick" to your hands, so that slipping or slipping out of your hand is almost impossible, even in the rain.
Newly developed coating & nano-coating
A multiple coating of all glass surfaces ensures optimal, loss-free light entry. The nano-coating lets water simply roll off - lotus effect.
