Optika illuminated dot. The dot it daylight useable as you can see. The dot & image is much clearer in person. The dot is confined and very precise. This Tactacam, video does not show the reticle & dot as clean & precise as they are. justice. I had the Tactacam on lowest setting and downloaded it in lowest , whatever you call it. This scope is a keeper. I probably should of waited until the BDC with a dot was in stock , however I do not really need hash marks for 10-60 yards. Going to be a great tree squirrel scope. I bought it from Scopelist or Euro optics. I tried the dichroic & did not keep it, got this one with a battery illumination. Awesome scope IMO.
