    Decent priced Chrono?

    I have an email into Caldwell's parent company, but wanted to get INGOs opinion.

    Just started reloading so I bought a Caldwell basic Chrono. First one worked OK my first outing. Only a few random anomalies. Second outing it threw a ~6,500+ FPS reading (9mm pistol) then refused to "see" more bullets. No errors, just acted like I wasnt shooting. So I exchanged it.

    Fast forward to this afternoon.

    New one is doing similar. Readings between 646 and 26,884*, LOTS of errors alternating between error2 and error3 (one or the other sensor fails to see the bullet) *Pretty sure my gun should have blown up if that were true, but no difference in felt recoil.


    So far this looks like a craptastic, semi reliable chrono. ( only have maybe 3-4 of the 10 loads I worked up that I trust the results on) Any suggestions that wont break the bank? I'd LOOOOOOVE a LabRadar unit, but that's a bit outside my budget.

    I thought maybe batteries, but reliability was sporadic throughout the afternoon. It actually seems to have gotten better as the day went on, but it wasnt a steady improvement. More of a sine wave. (bad, good, bad, good, bad, good...)

    Ideas?

    EDIT: It MUST have a smartphone interface or have a way to export the data. I'm spoiled by the features of this (maybe PoS) unit. I set the group data and hit record. It saved it to my phone via a cable and I didnt have to write anything down. (one of the anomalies can be seen below)

    Pro-Chrono Digital
    It's currently going for $95 in that above link and you may be able to find it for slightly less, but I'd call that a killer deal.
    It's even made in USA, for those to whom that is considered a bonus, as I do.
    I love mine, and that's all I can say that.

    I've been using a Pro-Chrono Digital for quite a few years. It is very user friendly and less effected by various light condition than any of the other chrono I have had. When shooting indoors under fluorescent light the optional light bar works great.

    I started using the Caldwell basic this year and haven't had any problems. I have noticed that the unit needs to be carefully lined up and shots need to be well centered (left to right) to prevent 'no read' errors but this hasn't caused wildly high readings.

    Are you positioning the unit far enough out (~15') that the gases exiting the barrel aren't causing problems?

    I didnt see in the manual anything about distance. When I fired up the app the default distance is "1 foot". So I presumed I could use it that close since they default to such a close distance. Who knew they would default to a non-workable distance.

    Support came to the same conclusion this AM. I'll try again with a longer distance.

    I figured it was either distance or you were having really bad luck getting two defective units in a row.

    Let us know how it goes, but I suspect your problem is solved.

    I thought it would turn out to be clouds, or trees...
    I've read that shadows moving over the Caldwell can detrimentally affect results.
    I did know that you needed more than a foot clearance though.

    I have one you can borrow. Caldwell. It's pretty reliable. Accuracy? I have no way to test. Seems within lines of the reloads on 9mm I've done.
    Only goofy thing is you have to plug in the phone end first, then the chrono. the app is goofy like that. Unsure on exporting, as I use a tracfone. it records shot strings, and you can save data, etc...
    otherwise, works rain or shine.
    Caldwell Ballistic Precision Chronograph I got mine through basspro on rewards points (for like 15$ on my end)

    that I discover each new day, is astounding.

    Thanks. Same one I have. Gonna try it at 15' and see how that goes. To export, you email the results. As cheesy and plastic as they are, they seem to have the app down pretty well. When I email the results I get a list in the body of all the data, and a csv file for each group. Pretty damned cool. And their customer service is excellent. They responded to me in only 2 business hours. I'm impressed.

    I still really want a doppler unit though. LOL

    I just checked the manual and it states 10'-15'. Bigger cartridge, more gases, more distance.
