On mine (Horton Hunter 3 dot), the dots are all the same size. But they do tend to blur together if the brightness setting is too high. I wonder when they changed this? I have the 2006 model. Do you know which one has the Huge 20trd dot? Because if I have to send mine back due to it blinking out on me, I sure don't want them to send me a replacement with the different size dots. I wouldn't care for that either... I'mnew to this also, so I'm still learning the basics... thanks.
