My new 33 year old ProChrony crapped out last month too. Same thing, display is gone. Someone has the new display on eBay but I couldn\’t figure out how to get in the old unit. I did find a used unit for $50 so I purchased that and I\’m back in business.
Now I\’m looking for the chorded remote so I don\’t have to get up and go look at it for every shot. The Bluetooth would be nice too but my pocket book wasn\’t that ambitious.
