yeah the uncertainty - covered that in this video a little: I've looked internally at a few of these & Its most likely due to the lack of processing power for the given the sensor distance. You can increase the distance between sensors, or increase the processing power, both have draw backs.

Radars... There was an interesting thread on AGF UK about radars, an old guy that worked on radars for 60 years popped in - he basically laughed at using a radar on something the speed, size & shape of a pellet for accurate readings. Given it is pretty clear its possible to do it - I think he...

I'm somewhat confident in saying I've most likely shot through more chronographs than any person - because I live shoot calibrate every unit that is made. I cannot stress enough how critical mounting is - it has taken many, MANY iterations, design updates and testing to get even a simple...

The distance from center to top is ~15mm & bottom is roughly the same, however alignment is absolutely critical (new software has alignment detection though - so you can detect if there's an issue) I would not recommend to use the outer surfaces on the Chrony as a reference point, and only...

The only other Chronograph i've seen with repeatability accuracy is the Pro-chrono DLX, but they specify it in timing ns... kinda frustrating, you'd have to do the maths on sensor spread & calculate a %. Adapters - all the work is still valid, you'd just add a 20.1mm round end to slide into a...

Your expectation of chronograph accuracy is far too high - as is most peoples. Due to manufacturing tolerances, unless they're live shot calibrated - you're just not going to get the accuracy of the actual pellet speed. You can get 1% shot to shot consistency, but you'll see a higher variance...

Going through a rebuild & struggling too... keep blowing out the green orings. Did get a few to work ok & then it was like the check valve was stuck - looks like the other orings are done. One question... note how hill give you the brass tip & not the o-ring..... is the brass possibly wearing...

I can only talk about the regular NateChrony - some barrels it does affect POI, others not - depends on the barrel. So i'll never make the claim. There's a few pro bench shooters that use it & just leave it on their barrel 100% of the time with great success - but again, I wont claim that...

(NateChrony - NOT the BuckChrony - ref BuckRails product page for the buck chrony) Like a 457 Texan at a few hundred fpe? yeah no issues: Inner is ~16mm, good for 50cal up to ~150-200fpe Carbon version on the way for the big power (which is what Papa used above) Slugs are actually much...

There are the variable adapters which allow it to be used over un-threaded barrels or moderators up to 55mm (i.e. Donny Sumo)

Doesnt that hang on the end of the barrel?

yeah 100% understand It also cannot be used with powder burners & isnt good with CO2, muzzle mount isnt a magical solution for everything & there's reasons to purchase different units for sure.

Yeah this was a design decision. I can add a screen to the Chrony, it'd be small, fragile, hard to read, add weight on the muzzle, add cost, maybe a hinge for it to fold out & face rearward (fragile!), if there's a problem you'd HAVE to come to me for a replacement. IMO a bad solution these...

Sorry if it sounded aggressive - not my intention. My point was also that "free shipping" is never actually free, robbing peter to pay paul as it were

Sorry - maybe I didnt put it well. There's 2 things with Chronograph accuracy: - How close the result is to the actual speed of the pellet - How consistent the results are at a given speed (cant think of a better word when talking uncertainty) Example: - Pellet speeds: 1000, 998, 999, 1002...
