458RugerNo1HELP!!! - ??? ref ProChrony chronograph
Hello all,
I've had my ProChrony chronograph for years and had ZERO trouble with it. It's been a great and reliable instrument, and in fact still is, however for some reason it's begun reading in METERS per second rather than FPS. I can't figure out how it got into this mode and damned if I can figure out how to get it back to FPS...
Once I removed the battery and reinstalled it and that fixed it. Now however it's doing it again and the battery trick isn't working.
Any of you know how to switch it back to FPS? My manual has been lost for years and I've never had occasion to wish I had it until now. It's been easy and user-friendly in the past. This one has me stumped...

Good luck and good shooting.

458RugerNo1Phurley,
You were totally wrong...
It took 3 minutes! Thanks alot, I did a "search" and immediately found the website, then it took about 30 seconds to open the PDF file and read the manual online...
Thanks! You're my "hero of the day"... I'll drink a beer in your honor later after dinner.

Good shooting.

My Chrony instruction manual gives directions on switching back & forth from M/S to FPS..... You need to ask the manufacturer for a replacement instructioin sheet.
