I have the 75mm 640 30hz non-pro Zeus. I have zeroes for two rifles saved in it. Sometimes in the field, I get confused about holding the front and back buttons down to do a NUC and hold down the left and right buttons which resets the reticle to 0/0 in the Rifle Profile that I am in. Is there a way to turn this function off? I can't for the life of me figure out why it is an actual feature.....
