Was the power lines the reason it wasnt reading the slow moving velocities? I have shot all sorts of projectiles over my F-1 and it will read everything.I have clocked arrows,pellets,BBs from air rifles all sorts of handguns,muzzleloaders,and rifles.The only time I have had trouble is right before dark when the lighting is too dim.

Mine will...Of course it is a Pact Mod One..

Something i just found out the other day that might be of interest to some of you. My dad got a F-1 shooting Chrony for christmas. We took it out to the local range. works good for some applications. however it still will not clock a slow moving pistol bullet or a 17 hmr bullet. it started reading some really bogus velocities. either really low or really high. I decided i'd look up what information i could find about it on the internet. first thing they say about it is don't use it in the vincinity if high tension power lines. lol. the local range sits under three set of HT's lol. might explain the pecularities. I agree that a chronograph is a necessary piece of equipment if you are going to get serious about making long range shots. you have to get intimate with the ballistics of you're particular rifle/ammunition combination. i learned a while ago that the book is not close enough to be counted on. Everyone's pressure/test barrels are different and data can be all over the map. for instance i have a savage 110 in .223 rem. in F.C. brass i'm loading 25.5 grains of H335 behing a 55 gr hornady v-max. according to speer #13 that particular combination should achieve roughly 3,000 ft/sec. Chrony says 3200 ft/sec. makes quite a difference in the realm of ballistics. I hope i'm not rattling on so i'll bring this to a close. i will finish with this statement. it is my belief that anything you do to make your shooting more precise, all help a little bit to improve accuracy. Conisistency in all things related leads to accuracy.

Wow !!!! Thanks for all the help guys. My summer "shootin stuff" is starting to trickle in that I recently ordered. Is is harder then chinese arithmatic waiting for spring to get here. But I will have time to get used to all the "shooting stuff"..........thanks again for all the wonderful advice and ideas !!!!!

My chrono is a Shooting Chrony with the remote readout. THe readout costs $65 to replace, but it sits on the bench. The entire rest of the rig - folding sensor unit, rod and screens - costs $35 to replace.

Have had it 4-5 years now and haven't shot it yet. The only other person I let shoot over it is my hunting buddy.

Yep, I'm a rookie on here, but I have to start somewhere and this seems as good a place as any to start. I use a Pact, and really like it. However when I was checking some shotshell speeds, I added a piece of .180 steel 4" wide and about 30" long. The front 12" was angled up such that it protected the chronys eyes 3" above the eye. If the wad or I hit low, the angle just forced it downward and nothing was hurt. I did exchange the tighting bolt for one that was a little longer to allow for the steel.
Wanted to protect my investment and it was of little or no cost. Just my .02 worth. Have fun with yours. It is a must have item I think.

If you happen to have a laser bore sighter you can use that to perfectly
position the chronograph in just a few seconds.

However for years I just just mine up by eyeball and never shot the chronograph or screens. It just is a lot quicker to setup with the laser.

Don't worry about it...Set it up right and remember that a scoped rifle will shoot a bit low going over the chronograph...Be real careful about letting others shoot over your chronograph and get one that has the repeater (readout modual) back on the firing line and not part of the screens. I have been shooting over my Pact One for the better part of 20 years and have only nicked one of the sensors (Hence the warning about scoped rifles)... (Hate that when it happens)

Wooden dowls is what I use as well. "Because someone shot a couple of the originals!!!!!!"

Good idea Dallan. Thanks for the tip. I just tried 1/8" dowels in mine and it fits perfectly. And it is easier to bend when installing the screens. I love this sight....learn something new every day.

I replaced my steel sunscreen rods with flimsy Shish-ki-bob skewers. I figured if I nicked a steel one it would break apart the plastic that holds'em in the base. If I nick a flimsy skewer it just breaks the skewer ... that was the theory anyway and it actually proved true once when I was a bit careless

I have a Chroney Master Gamma, (with printer and the works) I love it.

One tip that I use......I put black electrical tap 6" up on the screen support rods. That is the height recommended by the manufacturer. That way I can see at a glance with my scope on the lowest power if the horiz cross hair is at the right height. Of course I also make sure that the screen rods are equal distance from the vertical cross hair, too. But I pay more attention to the horizontal cross hair height. Better to blast a screen or screen rod that the chroney itself Don't ask me how I know, please I also use a tripod so I can get all the adjustments I need to make easily. I set the tripod 4 paces in front of the muzzle (about 12 feet). And finally, as has been suggested NEVER let anyone else use it unless you are there to set it up and check it out first.

I bought a Delta crony and I paid extra to order the protective Lexan covers... more to protect it from the smoke / fouling black powder rifles spit out. But it works great for sabot protection as well.

I place my rifle on sandbags, aimed at my target. I then remove the bolt from the rifle and begin to set up the cronograph. I usually have it 4 to 6 yards from the muzzle. I have it on a tripod so I can adjust height and angle. I look through the sunscreen poles back at the rifle to achieve proper postion and clearance. I then move back to the rifle, adjust the scope to the lowest power and make sure things look good from there too. You can shoot pretty high above a cronograph and still have it read so give yourself plenty of room.
