The chronometer display for FX Chrono’s enables you to keep an eye on the present performances of your air rifle. This handy accessory connects to the FX Radar Chronograph (Pocket Chrono) and the FX Barrel Chronograph wirelessly through Bluetooth. This does not take away that the chrono stays connected to the FX Radar smartphone app and its functions. FX’s display is mounted just under the eyepiece of your rifle scope on your Impact, or on the side accessory rail of your Maverick, and shows the velocity of the projectile leaving your airgun immediately. It also shows the amount of remaining shots in your magazine, and the battery percentage of your chrono. The chronometer display FX Chrono is rechargeable through its USB-C port.
