Clear, bright, built to last.

Low cost, high performance

From woodland birds to distant mammals, the Tremarctos 8×42 delivers bright, natural views in a tough, field-ready design you can rely on all day.

See wildlife clearly

See nature as it should be. The Tremarctos delivers a clear, bright view with natural colour and contrast.

Its balanced build stays comfortable during long days in the field, whether you’re birdwatching, surveying habitats or exploring outdoors.

Precision optics

ED glass lenses and premium prism coatings ensure the image you see has accurate colours and crisp details.

The 8x magnification and bright 42mm objective lenses give you clear views and the wide field of view makes it easy to follow movement.

Field-ready

The robust magnesium alloy body is waterproof to IPX7 and nitrogen-filled to prevent internal fogging.

Textured rubber armouring provides a secure grip while smooth focusing and a lockable dioptre help you fine-tune the view.

Ergonomic design

Long eye relief and twist-up eyecups make the Tremarctos comfortable for glasses wearers.

The included padded strap and protective case keep everything secure on the move. A concealed tripod mount thread gives added stability when needed.
