As if the itsy-bitsy FX Pocket Chronograph couldn’t get any handier.
We’ve covered this innovative device from FX in the past. As a quick refresher, it’s an airgun chronograph that’s not much bigger than a tin of Altoids. Oh, and it uses radar as the detection technology. That means no finicky light sensors, so you can use this device in the sun, shade, and even indoors. It doesn’t care.
With the first iteration of the FX Pocket Chronograph, you had two mounting options. You could stand it on the bench and shoot over the top. Or you could use the included tripod mounting plate. Both required a bit of alignment as you want to place the barrel about an inch over the top of the device with the muzzle just forward of its face.
The new muzzle mount adapter will ship with every unit from here on out. By removing the backplate of the chrony, you can swap out the tripod mounting plate in favor of the muzzle mount. Using rubber bands, just slap the unit on the barrel or moderator and start shooting.
By mounting the lightweight unit directly to your airgun, you remove alignment issues altogether. While the unit is light, it still might interfere with accuracy since it’s mounted directly to the barrel, so it’s probably a good idea to finish your velocity measurements before shooting for extreme precision.
