Vintage Shooting Chrony
Many years ago I had a Shooting Chrony. As I recall it was green and worked well until 52 grains from my .222 drilled its innards, stem to stern.
I replaced that with a ProChrony which also worked well. Finally sold it after years of not using it.
Today I found a Red Shooting Chrony at a yard sale. Asking price was $15.00. Its' 9 volt battery was corroded to near non-recognition, though the Duracell battery was labeled "use before 1991!" Otherwise it appeared to be in good shape and I offered $5.00.
New battery and it works great. Only control is a simple ON/OFF switch. Seems like maybe it will just tell me shot by shot velocity. Would love to track down a copy of the original instructions.
