The Delta Optical Titanium 10×56 ROH binoculars are binoculars with a 10x magnification, allowing to obtain better image detail at the cost of lower brightness. These types of binoculars prove to be the basic night equipment adapted to the eyes of older hunters whose eyes do not fully use the possibilities of the large exit pupil of the Titanium 8×56 ROH model. Regardless of the observer’s age, the Titanium 10×56 ROH binoculars may prove to be helpful in better recognition of the game, especially under the conditions of a full moon and during daytime observations.

The Delta Optical Titanium ROH series binoculars combine elegance and style with modern technical solutions. The abbreviation ROH stands for a series of hunting binoculars with a modern roof prism construction and lenses with a diameter of 56 mm. Thanks to special prisms and a well-thought-out internal structure, the Delta Optical Titanium ROH binoculars are probably the smallest and lightest binoculars with 56 mm lenses in the world. With a weight not exceeding 950 g the Delta Optical Titanium ROH binoculars have dimensions similar to binoculars with 50 mm lenses and overcome them with the possibilities of a slightly more than 25% larger surface of the lenses.

All lenses of the Titanium ROH series binoculars are coated with specially selected, multi-layer antireflection FMC coatings with an efficiency of 99%. As a result, the total light transmission is maintained at 90%, which was confirmed by the German DEVA institute. This is a better result than in other binoculars – the image in our binoculars is brighter and cleaner, despite the identical lens diameter and the same magnification.

The durable bodies of the Titanium ROH binoculars, made entirely of light aluminum alloys, are covered with a nice-to-the-touch, textured rubber. The internal focusing system with a centrally located adjustment knob makes focusing quick and easy, with a small range of rotation of the knob. The right eyepiece is equipped with an additional diopter correction for people with visual impairment. All the Titanium ROH series binoculars are completely waterproof and nitrogen-filled, which prevents them from vaporizing from the inside. Adjustable twist-up eyecups allow comfortable observation with glasses.

These binoculars are not only modern technology. The design and style of the Delta Optical Titanium ROH binoculars comes from Poland, because the binoculars have been entirely designed and developed in Poland. Their exceptional elegance and high quality of workmanship were appreciated in the industrial design competition “Dobry Design” 2013, in which the ROH series binoculars reached the finals. Each pair of binoculars comes with a practical case and a convenient carrying strap.
