Okay, i finished some tests today that gave me the answers on this question.
The Zr3 uses a splitter for the front heads, so that both will fire even if one is shot.
Blinders fire independently, so i decided to test the theory of a splitter on them.
Some time ago i played with a splitter on my slightly older units, the ones with the stealth fix, but before the updated ones with the 30 second test mode.
those seemed to be fine with a splitter, and i didn't notice any appreciable difference in performance, at least against an LTI.
Today i did some new tests, on an SUV that has no Veil, bra, etc.. and an M-20. it's about 6 mo's old and has the test mode option.
the short answer is, instead of 100' range PT's, the splitter caused PT up to 900' away. :shock:
I tested against an LTI and a Stalker. both guns got longer range PT's with the splitter installed, as opposed to without.
Anyway, just a heads up to anyone considering this.
i have some video of these runs, so i'll work on some at some point, but i have other vids i still need to do.
