please excuse my bad english, it's not my native language. I am a proud owner of a Docter 3-12x56 with the German reticle 1 (not illuminated). I usually use this scope for hunting wild boars. Especially in the evening and in the night. It's essential to have a good optic to recognice black boars in black nights. The Docter 3-12x56 a really good scope and a good deal for the money. It's not cheap qualitiy. These riflescopes are builded in Jena/Germany. Docter Optics is the successor of Carl Zeiss Jena. As you know after WW2 Germany was divided in a western and an eastern part. The Zeiss company was in Jena in the east. The head and some of the engeneers flew from the russians into the western part. There they continued their great work ("Zeiss West") and created a lot of new highest quality optics. Under the russian occupation the old Zeiss factory in Jena (east) continued to produce the approved models. Their products were typical "made in germany" in the best sense. From Zeiss Jena came binoculars like the 7x50 Binoctem, the 10x50 Dekarem and the 15x50 Pentekarem. They also created some riflescopes: For military use and for hunters in the western world to provide devices. The end of the cold war was the end of the GDR, the German Democratic Republic (the communist part). And it was the end for Zeiss Jena. The Docter company was created. They continued the good old Zeiss Jena work. And they designed some new models. The quality is really good, but the old Zeiss Jena qualtity was a little bit better.
With a riflescope from Docter you're on the right way. You'll buy very good quality. Okay, Zeiss West is better, also Swarovski or Schmidt&Bender (the price is also higher). Docter scopes have clear, bright and brillant optics, the sharpness of the edges is very good and the mechanic is reliable. The qualitity is basically better than japanese or other asian riflescopes. (Please don't forget, I an a german! ) Of course, Nightforce is better. Also some Leupold models (LPS and others).
For nighthunters the Docter 3-12x56 is a good deal. Today I would prefer a scope with an illuminated reticle.
