Video showing fiber dot in March dual reticle from 1.5x-10x in 6 levels of illumination.

Posted 05/11/2022

We took a video of the fiber dot in a March dual reticle with a Triggercam. This shows the fiber dot illumination in a dual reticle from 1.5x-10x in 6 levels of illumination and when turned OFF. We switched from the brightest state to the darkest state in 6 steps. The darkest level of the illumination is “1”. As the fiber dot is placed in the Second focal plane of the dual reticle, the size of the fiber dot does not change regardless of the magnification. The fiber dot reticle is much brighter than the glass reticle because the LED light is guided by fiber. Dual reticle is available in 1-10×24 shorty scope. Fiber dot reticle is available in 1-4x24SFP, 1-10x24SFP, 2.5-25x42SFP, 2.5-25x52SFP as well as 1-10x24Shorty FFP dual reticle scope.

 

When you look at today’s sky in Nagano where our factory is, the illumination looks red in the brightest state. Conversely, when looking at the trees, the center of the dot whites out. This is due to the camera’s aperture. When it is dark, the aperture is open, so the brightness of the dot is too bright and the center of the dot whites out due to overexposure. Against a bright background, the camera closes the aperture so that the red is visible. With the naked eye, the center fiber dot looks red regardless of the outside condition.

 

We tried hard to film this video, but please note that this video is taken by hand. The purpose of this video is to simply show you how the fiber dot illumination will look like. We apologize that the image is very low and far from the actual image which you will achieve with your naked eye.

 

 

The newest March Dual Reticle has advantages of both SFP and FFP reticle. It has the convenience of the FFP reticle scale which magnifies and reduces according to the magnification and the usability of the SFP reticle with the constant thickness (to the eye not the scale value) of the line as the magnification changes. Cross lines and the daylight bright fiber dot in the center is SFP. For SFP reticle, the thickness of the reticle line is consistent regardless of the magnification. Scale is in FFP. Merit of the FFP reticle is that the scale value is consistent and easy to calculate. Daylight bright fiber dot illumination is placed on the Second Focal plane reticle ensuring that the illuminated dot is usable across the entire magnification range; from a dot sight at low magnifications to a precise illuminated dot for long range precision shooting at higher magnifications with the use of the scale.
