| Shot my Master Beta Chrony. Just caught the back sensor but glass is broken and metal bent on one side. Will it cost more than a new one to get repaired? |
RIP Chrony
| It wasn't all in vain. I did get a few rounds over the sensors before I shot a tad low. Trying the new .44-150 CEB Raptor bullets in a Timberwolf carbine. 16.4 gr of Power Pistol clocked 2022 fps. If the accuracy is there I may have a new threat on the deer lease. |

yup shot mine day one. I had fired about 10 rounds was getting used to it, decided to double - tap and see if it would measure both rounds. well...guess the tripod got loose cause the muzzle blast made the chrono flip upwards and next round went through it at an angle. Still usable believe it or not but shattered the plastic clear glass in the rear.
I like that magnetspeed one. maybe someday i'll get myself that one. |

Quoted:
Shot mine first time out, only the diffuser rod which I had switched to wooden dowels. Replaced with another one from the range bag and kept on.  That's what I did after shooting my first diffuser rod. Changed over to really thin wooden dowels. I haven't shot one of the dowels yet...but they won't bend and get stuck in the holders. |

Popped mine the other day with a large caliber pellet.
First time for a hit to the chrony. Still going and didn`t totally penetrate the metal. If it would have been a firearm, things may have been different as far as functionality. I have hit the fan rods before. The replacement cost for them was cheap. |

Man, you guys need to learn how to AIM.
I have never shot my Master Gamma Chrony; after years of use and thousands of rounds, many of them pistol rounds from everything from .44 Mag (scoped) to G26 and Beretta Tomcat. Repeat after me: sight picture, front sight, breathing control, squeeze............ |

But it must be nice to be god and never screw up.

But it must be nice to be god and never screw up. Okay, so figure out the offset. It's pretty Goddamn obvious. Take a ruler and measure it. Then make sure you account for that when you shoot over the crony. BTW, the same concept holds for the offset for the raised irons on an AR15. This ain't rocket science. |

Okay guys, look, here are a couple of tips:
You want the bullet path over the Chrony to be about 3” directly over the sensors. So, you have to ADD to that 3 inches, the height from the weapon’s bore to the front sight. THIS VARIES FROM WEAPON TO WEAPON, scopes, raised irons, etc. all affect this measurement. Once you have this measurement, set up your Chrony and using a ruler, measure the vertical distance you need above the Chrony sensors. Now, take a length of masking tape and string it level from one sun shade upright to the opposite upright at the height where you need to set your weapon’s front sight or scope crosshairs in order for a bullet to clear the Chrony sensors at 3”. Tear the tape in half and wind each half around the corresponding upright. Now you have a permanent reference point at each sunshade upright that you can use to establish your sight picture. I do one better. Depending upon where you live and what time of day you like to shoot, you may not need to use the sunshades. I almost never need the sunshades. So, what I do is replace the steel uprights with 1/8” dowel rods. Guess what happens to the Chrony if you accidentally shoot a 1/8” dowel rod upright? Nothing. The dowel rod breaks, not the instrument. I have marked off a black band on my set of 1/8” dowel rods (using a “Sharpie”) so I have a permanent marker on my uprights for use in establishing my sight picture. Stop shooting your Chronies…that’s just too damn expensive.

Yup! blew mine apart too . The range where I am a member has a covered shooting area, benches with a apron out in front of it for prone shooting, so have to set chrony up under a cover, constantly getting error messages due to light conditions, was trying to get the bullet path over the sensors, and raised the chrony up incrementally till I tagged it. So my solution to not doing it again to my replacement is I take a target and glued it on a piece of cardboard 8X11. Depending on the sights I'm using I will either use the target long side vertically or horizontally. and either bore sight on the target [oh yeah - use clips and clip it to the second skyscreen supports - when I have it lined up remove the target] or use the sights. Also I sight in the downrange target first. This way bullet path is correct height and the sensors are lined up, One really big help to cure the error messages - I bought the LED sky screens - these babies really work, No more error messages. Compared my beta master chrony to my friends Ohler, it's amazingly close, and now with consistent light conditions my std. deviations and ES are reading either single digits or low 10's.
Like I was told - THERE ARE THOSE THAT EITHER HAVE OR WILL SHOOT THEIR CHRONY |
