LMBR R2A Ballistic Shooting Chronograph for Airguns (with D-SUB9 Connection)
The LMBR R2A has been my go to chronograph for nearly three years. It performs reliably in low light, indoors, outdoors essentially in just about any conditions. I’ve tested three units side by side, shooting through them one at a time, and the differences in their readings were minimal.
In my opinion, this design offers several advantages over radar-based chronographs currently on the market. With three different models available, there’s an option suited to almost every shooter or archer.
