The calculator is the issue to find a good one.
I had mine go south a couple of years ago.
I posted here and found a couple of the calculators for ET prediction.
Bruce made several versions depending on the years in which they were produced.
I still use mine and it has served me well for many years now.
When my calculator went bad I searched the internet and found a place on the east coast that would try to repair it. They would not make any promises on getting it repaired and they were a little pricy just to look at it.
I do not remember anything else about the repair service.
I may have kept some of the info in the race trailer.
If you can not come up with anything else other than a repair of a broken one let me know and I will look to see if I can find the old info on repairs.
I still have one broken one here next to the computer. Good physical shape just gives errors when you try to calculate.
Good luck in your search.
