The number you see on display is not your actual magnification. It represents how many times your base magnification is being multiplied, which is why it is referred to as 1x, 2x, 4x, and 8x.
For example, with the BlazeSeeker 210, the base magnification is 1.5x. When you zoom in to 8x, the base magnification of 1.5x is multiplied by 8, resulting in a total magnification of 12x (1.5 × 8 = 12).
