Sights with aiming mark type selection

Aiming mark type selection

— the ability to switch between different types of aiming marks, at the request of the user. This makes it possible to choose the most convenient brand, depending on the specifics of the situation and personal preferences: for example, in a dimly lit room, a collimator (see "Type") is more convenient to use with a simple point, and when entering daylight, you can turn on a more noticeable brand, such as like a circle with a dot or a cross. Similarly, you can reconfigure the night sight: if the distance is known, you can use the simplest hunting grid (for example, a cross), and when you change the distance to the targets, switch to rangefinder markings like “mil-dot”. But in optics, this function is extremely rare, and in a truncated version: in addition to the usual, unchanging grid, the user can turn on and off the mark in the form of a point.
