Ok, I'm a lefty and when I put the ctx in my left hand the screen contrast is washed out. When it is in my right hand the contrast is perfect, very nice. Makes it very difficult for me as a lefty to see. I think it's the nature of the LCD screen but puts a lefty in a frustrating position.(had three other people test it and agree) Anything they can do to make it better. To test on yours, put the coil on the ground centered in front of you, battery on your belly. Then leave coil in the same position but move just the battery end far left then back far right. Does your screen wash out when goes to the left? Any input would be useful, thank you
