Delta Optical company is on the market already for a good decade, and it has already become very well established in Eastern and Central Europe as a provider of products with a very good price/quality ratio. The Titanium series of rifle scopes are the perfect example of high-quality products for an affordable price.
Delta Optical Titanium rifle scopes are also the cheapest rifle scopes on the market that have optical fiber in the reticle, for best reticle illumination possible. Thanks to the optical fiber, the red dot in the reticle is very crisp and sharp. The illumination is very fine adjustable, with 11 intensity settings (Titanium 2.5-10x56 HD Di has digital illumination adjustment), that is usable in daytime hunting applications and even in the night. Except for three models (4.5-14x44 FFP, 6-24x42, and 4-16x42), all have reticle illumination.
These rifle scopes are mostly meant for hunting use, but some models are also usable for sports shooting. All rifle scopes from the Titanium series have fully multi-coated lenses for s brighter image and contrast, and some models with ED abbreviation have also Extra Low Dispersion glass inside for even better image quality and no color dispersion.
The housing of these rifle scopes is made from a single piece aluminum, so these rifle scopes can withstand the strongest calibers, the 1-inch main tube rifle scopes up to 4000 Joules, and the bigger tube models all the way till 6500 Joules. This means you can use them on any caliber, even on big magnums. The tube is nitrogen filled for fogproof use at low temperatures, and the rifle scopes are also O-ring sealed so they are also waterproof. Some models have fixed parallax at 100 meters, and some have a parallax turret located on the side of the rifle scope.
In the Titanium series of rifle scopes is also one model that is specifically designed for air guns (Titanium 4.5-14x44 FFP HFT), that has the reticle set in the first focal plane(reticle changes with zoom) for easy measuring the distances to the target.
