Master Chrony Alpha Chronograph

If you own any tun-able air gun this is a must have. Makes shooting and tuning easy and precise.

Pros
Takes the guess work out of tuning.

AT FRIST I WAS HAVING TROUBLE , GETTING LOTS OF ERRORS THE FRONT SENSOR THEN THE REAR SENSOR . TRIED OUT DOORS , IN THE SHADE ,IN THE SUN , OVER CAST JUST COULDN'T GET IT TO WORK . I WAS GETTING LIKE 1 OR 2 READINGS OUT OF TEN . WENT TO OTHER DEALERS TO READ THERE REVIEWS TO SEE IF OTHER SHOOTERS HAD THE SAME PROBLEM . I FOUND OUT THAT THE SENSORS ARE VERY SENSITIVE IF THE LIGHTING IS NOT RIGHT IT DOESN'T PICK UP THE PELLET THATS CAUSE ERROR PROBLEMS. I READ SOME GUYS PUT LED LIGHTS TO HELP THE SENSORS PICK UP THE PELLET SO I WENT SHOPPING LOOK AT HOMEDEPOT LIGHTING DEPARTMENT GOT SOME IDEAS BUT IT COST ALOT SO I PUT THOSE IDEAS ON THE BACK BURNER AND WENT LOOKING AT WALMART . I FOUND SOME LED LIGHTS IN THE HARDWARE DEPARTMENT THEY WERE JUST WHAT I WAS LOOKING FOR 2X5X1 CAMO NICE LIGHTS FOR 6 BUCKS SO I BOUGHT 2 LIGHTS. WENT HOME TO TRY IT OUT . I JUST TURN ON THE LIGHTS AND LAYED IT ON TOP OF THE SHADE AND TOOK TEN ROUNDS AND ALL TEN REGISTER I WAS HAPPY. IT WORK IN ALL CONDITIONS. RIGHT NOW I SHOOT FROM INSIDE MY GARAGE TO MY TARGET 20 YD. OUTSIDE OF THE GARAGE. IN MY GARAGE I HAVE FLORESCENT LIGHTS ON AND IT STILL PICKS UP THE PELLET. SO IF YOU HAVING TROUBLE WITH ERRORS 2 $6.00 LED LIGHTS FROM WALMART WORKS GREAT FOR ME.

Pros
18 FT. CORD DOES THE JOB WITH THE RIGHT LIGHTING

Cons
THE SHADE COULD HAVE A BETTER CONNECTION

So far this has given me more info than I thought of asking for. First off is that I'm shooting Kodiaks 25 FPS faster than expected, woot! Second; they are VERY consistent with 10 shot strings as low as 3.9 FPS standard deviation and a long term of 6.7 SD for hundreds of shots. Now I can make better use of Chairgun software and the Map6 reticle.
Thirdly, I had semi consistent results with .22 JSB Exact jumbos that showed great potential and otherwise. The extreme spread was 50 FPS! My conclusion was that they were too loose in the bore to stay seated while I closed my break barrel springer and they fell back into the O ring/breach seal void and allowed blow by to occur for some shots. Fourth, I deep seated a variety of pellets and found that the extra volume behind the pellet reduced the velocity by 40 FPS on average. Paid for itself already by now!
When I reached my second 1,000 shot lube I slightly over lubed by 25 to 50 percent and after all the dieseling was settled I lost 10 FPS on average for about two tins! Won't do that again! What made me think I was smarter than the engineer? Not the Chrony!

Pros
Easy to set up and the remote display is easy to read with the screens positioned at 10 feet away. Works in a variety of light (not rain lol) and if you want to use it indoors use a bright incandecent light source lighting a bright ceiling above the screens without the diffusers .

Cons
As mentioned it's a tight fit so I never tried to re-package because I set up 10 foot away and shot offhand. If you leave the display outside of the box there is plenty of room for the 18' cord and the 9v battery. If you place the screens 3 feet away and shoot off the bench you only need to separate a few loops of cord and packing up would be easier. The only con is I had to tap the camera mounting hole because of paint overspray, big whoop.

Easy to set up and use. A must for tricking out your pellet gun. Any tuning you do to the gun is shown by the FPS you see on the chrono.

Pros
Easy to set up and with the remote. I have it on my table as I shoot a string of ten shots for viewing. Gives and high and low reading and a average after shooting. A must if your trying to achieve more out of your gun.

Cons
When I put it away and fold it up, there is not a lot of room to get all the wires from the remote in. I have to be careful not to close the unit on the wires and cut them.
