single dot eotech

I was hoping someone could help me out and post a good picture of the reticle on one of the eotech single dots. I’m a single dot fan but love the eotechs. I would like to try the 511 D1 or 552 D1, but I’m scared the dot will be too small for up close. Any pictures that show the single dot would be very helpful to me. Thanks in advance.
