I looked around the other subforums a bit, but not much to be found. I was wondering what types of chronographs, you guys use, if there are good ones out there, I read that some skyscreens give crap results. Any help really. I looked at the "Chrony Gamma Master" seems like a decent model. Couldn't seem to find many dealers for Pact around. That seems like it might be one of the best. Thoughts?
 
chronos

I was in the same boat a few years ago, I finaly settled on the ced mellium 2. The only issues I have had have all been the operator, customer service was quick to answer and questions. I read a review that said it was very comparible to the ohler 35 which is supposed to be the best. If I had to do it again I would make the same choice. They also have a whole system that you can purchase/use in conjuction whith the chrono. thanks
 
For simplicty and accuracy vs price the Chrony is hard to beat. made in Canada, too.

mr. Chrony used to test new models and components at the range behind my house. he would line up a number of units on a plank and shoot across all of them. In the middle was a fancy ohler, with the screens separated by twice the usual distance, to increase accuracy.

I was always impressed with the Chrony results.

I did that test myself. I put my Chrony in front of an Ohler and got a reading a few FPS faster on the Chrony, then I reversed them and got a few FPS faster on the Ohler. So for all intents and purposes, they were giving identical results.
 
I have a CED M2 and very happy with it. I had a Chrony and it was useless, just my opinion of course.
 
I have and like the Oehler 35P... every shot is measured through 2 chronographs and the computer will mark a false reading on the printout and ignore it in the tally. In my opinion it is one of the best if not the best for the money...
 
The achilles heel with the "Shooting Chrony" is the hinged base. If that base in not fully extended, or if the diffusers catch wind and flex any, then the sensors tend to point towards each other slightly, and you will get different velocities if you fire low in the chrony versus higher in the chrony.

The CED are as good as you can get. I understand Ohler has not been making their excellent chronograph for some time now.
 
Actually, the PVM-21 is superior to all. Do the google.

Yep! Upgraded from a Shooting Chrony (gives false readings in low and intense light, doesn't work well indoors) to a CED M2 with IR. It's much better, but still has inconsistencies in quite a few lighting conditions. My buddy also had the CED and got fed up with that and with it being too flimsy to leave assembled during transportion. He bought the PVM-21.

There is really no comparison... it's a far superior chronograph. It works flawlessly under almost every lighting condition (exception is when the sun is directly above), but it actually knows when it won't work and warns you. The "sweet spot" is HUGE and it's ridiculously well build so you don't have to disassemble it. Setup takes seconds with it... no fiddling with alignment.

A high quality chronograph is like high quality optics; you pay for the quality and you can't really appreciate the difference till you've used it. It's definitely on my list of equipment upgrades.
 
The Chrony is a great bang for the buck. A little trick- put clear packing tape over the sensor holes, and it significantly mitigates problems with lighting affecting readings.

I've also read and heard stellar reviews about the ProChrono Digital, which is probably what I'd buy if I needed another. The CED M2 is supposedly a great chronograph, but it's spendier than the other two. The fact that Chrony is Canadian-made had a large influence in my decision to buy one, since we need to support Canadian industry as much as possible in this economic environment.
 
PVM-21 is like $800 though..I don't think a false reading here of there is $500 more than my CED. But each to there own..I got mine right from CED.
 
Do any of the 'other' manufacturers offer their version of Oehler's PROOF CHANNEL™

WHAT IS A PROOF CHANNEL™?

The PROOF CHANNEL uses three skyscreens and two timers to make two velocity measurements on each shot. The Model 35 measures two velocities on each shot, it automatically compares the two readings, and it waves a flag if they don't agree within reasonable limits.

If you haven't used a chronograph before, the PROOF CHANNEL sounds unnecessary. If you have used a chronograph, you've certainly questioned some readings. Glaring high or low readings are easy to discard, but readings within five or ten percent of expected velocity are not easy to confirm or deny. The important question is, "Do I have reason to be concerned about my load, or did the chronograph make an error?" The PROOF CHANNEL tells you immediately if the chronograph reading is suspect. You can trust a friend who honestly says, "Oops, I might have goofed on that one."

The PROOF CHANNEL is like comparing your checkbook balance to the bank's balance. If the balances agree, they are right. If they differ by a few pennies, you assume the bank is correct and accept their balance. If there's a large difference, you don't trust either balance until you find the reason for the problem.

Most skyscreens will function under perfect light conditions, but they all fail under bad conditions. You expect skyscreens to fail when it gets dark, but there's a huge twilight zone between perfect conditions and obvious dark. It is better to have no chronograph reading at all than to believe an incorrect reading. With Oehler's PROOF CHANNEL you get positive assurance that your readings are correct, and the quality of your loads will reflect that assurance.
