Part Number:  30778

NEW improved Opticron Oregon-4 monocular with Oasis multi-layer optical coatings.

Opticron's Oasis coating enhances light transmission, colour and contrast.

Otherwise, the monocular looks and feels the same as the original Oregon-4 and retains the features that made it so popular: nitrogen-purged waterproof / fog proof construction, twist-up eyecups, long eye-relief and tactile rubber armour.

Fits nicely in a jacket pocket or car glove compartment.

An excellent monocular for birdwatching and nature observation.
