Pro Chrono vs FX Chrono?

I don’t have both, but they were the two I considered. I went with the FX and I am very happy I did! I love how small it is and that I can throw it in my range bag. After coming out with the barrel adapter, they made it much better. Sure, it does lower the POI because of the light weight, but I just adjust for it when I’m using it.

It works great and I consider it one of my better purchases. It is very easy to use, and I like that I can set up many different profiles, for each rifle or each ammo. It works well during operation for keeping track of the string, and it saves well. 
 
Well, I had forgotten about this one. I had bought it from China a while back after watching one of Joe the Cyclops videos and had it sitting there all forgotten about. It only measures in MPS, but it works flawlessly without giving errors or needing a light source. It's rechargeable via USB cable. Not as convenient as what I had before, but I think it was like $30 and I already had it, sooooo..... For now, that will be it along with my calculator to figure out FPS. Guess will buy a better one one of these days when I can make some carbon and water as my daddy use to say.

Print out mps to fps chart and laminate it for quick glance reference for a fast check lookup instead of having to constantly type in numbers through an online converter or a manual calculator (OMG). Like learning a second language you be speaking European in no time...eventually mps gonna be second nature to you...
