Chronograph problems......

I know damn well I can't be the only one here to do this but, who else has accidently SHOT their Chronograph? I done that earlier today while gathering data for my P-Rod after installing a heavy hammer spring. I clipped the little hood over the display on my Cauldwell. No damage per se, at least nothing a small file can take care of.

Yep, shot a couple of them. My ProChrono has a hole in the face of it now from my error. Luckily, I missed anything critical, either on the display or the internals. I just popped the top off and shook out a couple of small pieces of plastic and put a piece of black plastic tape over the hole. Good as new. My all-time chrono screw up was with another one when I had the great idea that I would chrono a shotgun load, which didn't turn out well at all. That one didn't make it home from the gun club.
 
I used to have a shooting chrony but I shot it one too many times trying to get it to read my air rifle indoors. I decided to buy an inexpensive chinese replacement and I think it works better. I shot one of them too, however. I was shooting 10 grain knock out slugs from my P35-177 and they were flying wildly. One clipped my first tripod mounted chinese one and broke the plastic box with the electronics and it didn't work after that. But the replacement was only $20 and reads in fps, which the old one did not do. I think it would be hard to shoot the inexpensive barrel mounted ones, even I have not done that, but tripod mounts are still at risk at my house. It's nice when a replacement is only $20.

I have a Marauder 22 synthetic stock I'm trying to tune myself and I originally bought the 35 dollar chrony off Amazon. The kind with the barrel clamp. I worked great for 6 or 8 months and just stopped reading. Would not record a shot. I decided to buy the ProCrony Deluxe. So far it works great but I had to learn about light. My cheap one worked great in the shop but the ProChrony didn't. Seems my lighting in the shop fouled it up some how. Now I have to get the door open and get some outside light on it then it works great. I am aware that there is a light bar for it but am going to keep that $60 to spend on pellets. Not that hard to get outside light here in CA. Anyway, I recommend the ProChrony and also hear good things about Caldwell.
 
I've shot my Caldwell three times now. Every time it seems it has to be with a bigger bore, heavy slug so it does some pretty good damage. The first time was the best one. Shot through close to the top of the faceplate, making shrapnel plastic bits of the inside, ricocheting down to blow the battery and cover out of the bottom. Removing the broken pieces, I discovered a random capacitor in the bottom that I could not find where it came off the board at. So I rewired the battery terminal and it worked just fine. Since then I have got couple of good "skips" off the top also that did some good gouging and cracking. I did buy a "spare" that is a few percent lower in speed, but it hasn't been needed, yet.
 
Agree "shooting chrony" is the one that gets hit due to needing to be close enough to the sensors for a good reading.
Mine never worked at all with the sun shades so the stayed as new.
But every 1,000 or so shots it's fun to slap em up side the head (and al my friends enjoyed doing so also (except the one who prefered to shoot the porch rail).
A few .177's, the center hit on rear sensor was the Carer 707II set at 99fpe, the DAQ .458 blow it off the rail (just the air) and the misses laughed as my big concern was reading the screen as it flew 10'.
Still worked every time tho. Only switched to the pro chrono for the camera/tripod attachment and they were just about the bet you could get back then.
Good times.
