    Did you do a search on EBay for “barrel band FX”?

    Hope to be able to use the final app (or program) to estimate (within 1-2%)  pellet velocity. 

    The simple version (already released and available in original (ods / open office) format and excel) and this version (google sheets) both calculate those estimations which generally end up within 1-2% of real world data provided you input the correct data from your rifle. The final spreadsheet will just have a TON of added features, such as  fpe losses based on port size/barrel length/pressure drop (reg volume), hammer data (speed, lock time, energy and comparisons), shot string analyzer (10 per gun/10 guns) that has a function to determine loss from chrono distance and add to the string if desired, as well as custom acceptable ES (graph will give a good visualization of what is within and what is outside of said custom ES), comparison of strings,guns, and projectiles, max shot calculator, tank fills calculator, more enhanced external ballistic data, ability to run in both metric and imperial (across the board, even converts all current data to metric or imperial(optional)). The advanced version will basically take care of all the needs your average, and more advanced pcp user needs. I am always open to add more as well! Suggestions always welcome.

    Sounds good.  As long as it's user friendly.    Where would you be able to get the correct measurements?  I assume that if your PCP is stock and not modified the data would be the same for everyone.  Where would you get that data for the Impact 1st Gen .22 and .25 or the .22 FX Crown?   

    Never mind, just noticed your post: https://www.airgunnation.com/topic/popular-gun-specs-data-request/     Excellent!

    You should be able to measure muzzle velocity with the FX chrono with the first shot.  Then move you FX Chrono downrange (do not exceed the distance of your Bluetooth range)  and measure the pellet velocity at that point.  As long as you are using the same pellet and same power behind it (reg settings, etc)  -effectively the same muzzle velocity – you should get pretty close the right numbers.

    Couple of things: 

    1.  You need to position the FX chrono downrange within a few inches from and directly below the pellet''s path

    2 . Do not shoot the FX chrono.(use a steel plate in front of it)

     

    If you want to use your Shooting Chrony together with your FX chono for BC, shoot a couple of pellets with both the FX chrono and the Shooting Chrony setup in a way to measure muzzle velocity for the same shot.  Note the difference between the two measurements of each unit. You can adjust the FX chrono +/- 2% to match the Shooting Chrony. Or just use the two numbers you got and do not forget to calculate that same difference once you setup one of them down range.

    It maybe easier to setup the FX chrono downage a foot or two away from the target and 3-4 inches below the pellet path's facing the aimpoint.  Use a steel plate or other physical barrier. 

    The wireless range is normally 10 meters (33 feet)  for the FX chrono as far as Bluetooth, but the BLE module used in the FX chrono has the capability to work outdoors up to 100 meters. However, it does not seem to have an antenna that would allow such a range. .

    He clearly revolutionized the quality of pellets.  I wish I would have JSBs when I first started the hobby.  Would have saved a lot of frustration.  RIP

    Finger may have been further out.  When you were looking through scope you lose some of the orientation of your hold and your finger was in front of the barrel.  

    However, the velocity drop for an entire magazine after that with no other changes to the gun is strange.  Did a seal blow out towards the front?  Is your internals modified anyway, like enlarged transfer port, etc?  Any aftermarket parts that may have failed and got blown out and ricochet??

    Hatsan coming up with new focused models…  FX has some competition.

    I hope it has a built-in chrono or a way for the computer to calculate velocity from power/pressure/vale timing and the given pellet weight….   If it does have a separate built-in chrono it should solve to problems of the chronos they had 10 years ago.

    I agree about the marvel of technology…for 2008.    I have an MVT with the bottle instead of the slim tube.  The reasons many people were averse to this setup was the chrono located at the end of the muzzle.   It was prone to fouling from lead dust and mishandling during barrel cleaning.  Also the wires running to the chrono sensor were really thin and flimsy, damaged easily. Add to that the initial problems with the computer forgetting the velocity settings which was later corrected by Daystate.  However, a software update cost north of $400 by an authorized dealer. 

    It was a proprietary software that Daystate that would not allow access to, thus the software could not evolve as in open platforms.  The software programmer equipment was not available on the market except for a few that slipped out of the hands of some dealers and were passed around to select insiders who had to keep then hidden from the public. May Daystate was worried that some UK or European owners increase the velocity and power into the uber-restrictive FAC limits.   Or maybe that was a way to ensure "quality-control" of their rifles being serviced by authorized dealers only, at an extraorbitant cost.

    By the time Daystate released a $400 programmer to the public around last year, an enterprising European hobbyist came up with a much superior drop-in replacement board for $220-250 that can be adjusted/programmed by the user. The board allowed for much more precise and reliable setting of the power curve resulting in more constant velocity and ballistics. After the initial excitement about the Daystate programmer many just walked away with a big yawn…to little too late…too much money.

    The initial battery being NiCad was replaced by many with a Li-Po battery that was much lighter and had a longer effective life.  However, the NiCad only need charging every 2,000 or so shots anyway. 

    I like my MVT and still marvel at the technology of 10 years ago that was ahead of its time.  Lesson learnt from Daystate stubborn old-fashioned risk-averse proprietary corporate culture (void of any change and constructive input by the public), was FX's new line or rifle and accessories that revolutionized the industry.  Now Daystate is slowly playing catch up…the "noble" UK way…with cautious elegance at a high-noon-tea style pace…

    I agree, a laminate style with a better designed built-in chrono and user adjustable/upgradable settings could be a well-selling item.  However, knowing FX, they will beat them to the punch again if FX decides to go the electric way for some of their lines of products. 

     

    Would this change the game for Daystate?  https://www.airgunsofarizona.com/blog/2020/01/coming-soon-at-aoa-the-new-daystate-delta-wolf.html

    For the ATN you can also add-on a range finder that mounts on the scope itself  (semi-integrated) and feeds range data in to the scope's computer for aimpoint correction.

    Will fixed power versions be something in the future?

    Definitely something we'd like to do. I think fixed power scopes are waaaay underrated!

    True.  Cheaper and clearer than variable scopes (less parts/lenses) and does the job well for a good range of targets.

    This is much better. Feels light and is light.

    What brand is this one?  Amazingly light with a scope and mod…

    Like others said it, let it lead-in again with 50-100 shots so the lead builds up and provides an even surface.  Also, make sure the barrel is mounted securely.   Try a pellet that offers more resistance when feeding it in (larger head diameter)   Feed by hand.
