Hey, fellow AR4's. I have been watching the post for a few month's and have not seen what i was hoping for. i have had issues with my vision since i updated to the 4.0 software. had no issues with the previous software but i like the homing speed with the new 4.0 i run the default ar4 settings under the 4.0 and all other functions of the update run great... (minus the odd reference in the oppisite direction from time to time)? that is minor to the vision issues i am having as i can not even get a find on a perfect vision find.. pictures match and get no percentage or referance?? On the previos version no issues 98.7% match? i would divert back to the previous version but the homing sequence on the 4.0 is much much better as well as the options.. any help would be great.
