The Expert 8x40 fully meets the requirements of enthusiasts (hunters, fishermen, gamekeepers, zoologists, ornithologists and nature conservation specialists) who use optics for professional purposes i.e. for those whose daily contact with wildlife, often in inclement and even extreme conditions, is an everyday experience. The Expert's unique design immediately attracts attention. The progressive optical system, based on an innovative Porro prism design, is encased in a solid durable body and lies at the core of the Expert 8x40 binocular. The distinctive feature of the binocular Expert VM 8x40 Marine is the yellow inserts of the lens caps and eyepiece areas. This special coloring makes the binoculars more visible.

The non-axial construction (both optical channels are in a single body) is very reliable: the binocular is highly resistant to shock loadings and vibration. The Expert’s carbon body is light whilst at the same time being made from one of the strongest composite materials.

Service durability of the binocular is excellent being IEC60529 IPX7 rated. The hermetically sealed body protects the binocular from rain, the ingression of a large body of water, such as a wave breaking over them, or even total immersion - accidental immersion in 1 m of water for up to 30 minutes. The nitrogen purged optical system prevents lenses from fogging in case of a sudden temperature drop.
Exterior flat protective filters, installed in front of the objective lenses, shield the optics from sand, dust and moisture.

The Expert VM 8x40 has an optimum magnification for mobile field use; its light-gathering power ensures troublefree operation both in the daytime and in twilight. This variant of the Expert 8x40 offers viewing modes that can be changed by means of two switchable internal filters. The Contrast Mode is used in twilight conditions for enhanced image contrast and for visual fog reduction. Operation in the Reflection Mode minimizes, or neutralizes, the dazzling effect of light reflected from non-metallic surfaces (water, snow, ice and glass).

Every thing has been thoughtfully designed in this model: the eyepieces are adjustable allowing a comfortable interpupillary setting; the ergonomic eyecups protect the eye against lateral ambient light; the Eclipse-M lens caps are permanently connected to the binocular body so cannot be lost and they also protect the front optics from raindrops; the neck strap is attached to the binocular and can be immediately removed if necessary.
