Second Zero | New Bullet Drop Compensator System | Axeon Optics
The Second Zero is the fastest bullet drop compensator system. It shifts a target image by the same amount a bullet drops giving you an additional zero distance.
Looks like a budget Tarac
"Invented by John Baker of TACOMHQ, the patented Second Zero®, is a prism driven optical device configured to bend light at a precise minute of angle to achieve an additional zero (second zero) downrange."
Anyone play with one of these yet? Not sure how precise it is, but might be fun to put on a 22 to shoot ELR.
