    Just as a proof of concept, I jerry-rigged the FX radar chrono to the end of my tank on the FX Crown.  It worked, measured the velocity seemingly reliably.  So wherever you aim the rifle the radar chrono will read it.   Should work on any rifle where there is space below the shroud and/or the barrel. 

    Also should be able to use it with those 3D printed air-tank rings someone makes on this forum where you can attach a tripod to your bottle.  Or just extend a rigid rod from the tripod mount location towards the end of the barrel.  or if you are not worried about POI change, just make a clamp and hang the radar chrono from the shroud/barrel and mount it below towards the end. 

    Good opportunity for folks with 3D printers to make some money if you make a nice looking and functional design…

     

    if FX would get rid of the 3 heavy AAA batteries and replace them with rechargeable li-ion packs….and also get rid of the heavy metal base-insert…..the FX radar would have a negligible weight when mounted on the end of the air bottle/shroud/barrel.   Have some other ideas, but later on those…

    Interesting. I received my FX radar last week and yesterday was the first time I had to check it out. I could not get readings unless the chrony was at the very end of my barrel (moderator). If it was closer me, as is with this adapter, I got no reading. It seemed much more finicky than I expected. Was I doing something wrong??????

    Idoc  if the velocity you are shooting is outside of the setting on the FX radar it will not register. For example, if you shoot at 500 and you set “High Power Airgun” which is 590-1099fps it will not register the shot  

    was the FX radar parallel with the barrel? Maybe the metal mass of the shroud or barrel caused a reflection  If it was parallel, was your power sensitivity setting high enough (“lowest” label) to register the shot? 

    I shot mine standing up aiming at the pellet catcher about 6 feet away.

    Keyman looks the part , innovative! Is that a range finder? How is it triggered? Could not find it online, except a huge military version.

    I was shooting my .22 Compatto at 840 to 790 and the minimum return was either on 20 or 10 but I never tried the "lowest" setting. That may have been the problem. As best I could tell it was lined up with the barrel but not sure how sensitive the alignment is. Thanks for the help.

    Yes, it is VERY sensitive to alignment with the barrel. If you take the 4 screws out of the back, the heavy metal piece with the threads for the bipod, slips right out, easy peezy.
