Vortex Ranger 1800 vs. Sig Sauer Kilo 1800 BDX – How do they compare?

Size and weight

I would advise you to go for a light option with the aim of having light shooting gear. The Vortex Ranger 1800 weighs 7.7 ounces, with dimensions of 3.9 x 3 inches. You get a similar package if you purchase the Sig Sauer Kilo 1800 BDX as it weighs 7.8 ounces, with dimensions of 4.1 x 3 x 1.4 inches. When looking at size and weight, the two are similar because they have close weights and dimensions.

Optical Performance

To determine which rangefinder is best for you, we will look at the Field of View, Magnification, Objective Lens diameter, Exit Pupil diameter and Eye relief in both.

So, how wide of an area is encompassed in your rangefinder’s image? The Vortex Ranger 1800 offers a field of view of 315’ @ 1000 yd / 105 m @ 1000 m. The Sig Sauer Kilo 1800 BDX offers the same field of view at 315’ @ 1000 yd / 105 m @ 1000 m.There is no difference between the two when you look at the Field of View.

The Vortex Ranger and Sig Sauer Kilo 1800 BDX have the same magnification power. You get up to 6x magnification of your image on both rangefinders. This is just enough to get you going on your shooting journeys.

The Objective Lenses of your rangefinders allow light to pass through so that you can have a good image resolution. The wider it is the more light can enter, giving you a crisp image. In this case, the Vortex Ranger 1800, and Sig Sauer Kilo 1800 BDX have the same Objective Lens diameter at 22 mm. This means that you get the same resolution if you purchase either of the two.

If you wear glasses, how far back can you be from the eyepiece and still see the whole field of view? The eye relief of your rangefinder answers this question. The Vortex Ranger 1800 and Sig Sauer Kilo 1800 BDX have the same amount of eye relief, coming in at 17 mm. There is no difference between the two in terms of how far back you can view the image from.

Lastly, we will look at the exit pupil. It basically directs the image-forming light towards your eyes. The wider it is, the better the quality of the image formed. The Vortex Ranger 1800 has an exit pupil diameter of 3.9 mm while the Sig Sauer Kilo 1800 BDX comes in at 3.6 mm. There is not much difference between the two, but the Vortex Ranger 1800 takes the win because of its wider exit pupil diameter.
