The Endeavor ED IVs offer incredible low light performance and bright, high definition viewing is delivered through the innovative pairing of Premium HOYA ED (Extra-low Dispersion) glass and SK-15 Prisms, allowing you to experience nature in a totally new dimension. This winning combination provides optimal image quality, excellent light transmission and colour fidelity for a remarkable viewing experience.

In addition to the Premium HOYA glass and new SK-15 prism, Endeavor ED IV has been upgraded with advanced MultiGuard Coatings that provide even better light transmission, especially when viewing in low light conditions.

Beyond the optical performance, the Endeavor ED IV was designed for comfort. With an incredibly light magnesium housing and excellent balance, these are binoculars that you can use all day. Convenience of use extends further to our newly integrated central dioptre and three stage adjustable locking eyecups for setting the perfect eye relief. A tripod socket is incorporated in the front hinge for those wishing to use a binocular tripod adapter, (such as the Vanguard BA-185), for enhanced stability or for long periods of use.

The binoculars are nitrogen purged to be completely fog proof. Combined with the hydrophobic properties of the lens coatings and a rugged build that includes a fully waterproof rubber armoured body, the Endeavor ED IV is equipped for any conditions that you find yourself in.

Available in the popular sizes of 8x42 and 10x42 with a refreshed, modern design that provides enhanced ergonomics and the enhanced optical performance means the Endeavor ED IV has reset the standard of quality in the Endeavor binocular series.
