The Constantine riflescope is compact and doing really well. It is featured for the etached glass VOS-TMOA reticle, good sharpness and brightness. Ring and dot are illuminated in 11 levels. The quality of the scope is no doubt very good, T6061 monotube, Schott-Germany lenses, multi-coated, real 1-10x power and very good optical performance in this price range. The appearance is really nice, hard anodized surfaces round off the package. The Constantine is of course also nitrogen-filled and IPX6 certified, waterproof at a depth of 1 meter for 30 minutes. The adjustment of the turret works perfectly, they give a clean acoustic and noticeable feedback. As a bonus, Vector Optics includes an open tactical turret for elevation adjustment.

I tested the Constantine at distances between 25-300m. Whether on a 50, 100 or 300m mirror or 25m and 200m drop plates, it is always a good companion. Falling plates at short distances with simple power are almost addictive. For the price offered, the Constantine is a very interesting product alongside the Zalem. Especially with regard to comparable products from other competitors. I don't want to ignore the fact that Vector Optics Constantine 1-10x24 is one of the best riflescopes in its price range for me.

The Vector Optics Constantine 1-10x24 SFP costs €479 and is worth every penny.
