I'm seriously thinking of getting a V1 to use when on trips in the USA. I live in a communist province where everything is illegal, hence the need for the STi. I've been using it for a while now. Can I use the STi (hardwired and hidden) with a V1? Do they interfere with each other? I would keep them about 1 foot apart. I've seen multiple youtube videos showing two RD's in the same vehicle. Just wondering if it's worth the investment. I love the arrows!! On a side note, I called VR the other day to inquire about Spectre Proof V1 anytime in the near future. A very nice, elderly lady said it's a known problem that they're working on. That would be awesome for us in areas where RD's are banned if Mike could Spectre proof his creation. I read somewhere that there is supposed to be a guy in Australia who can successfully make your V1 Spectre proof. Posted on one of these forums I believe.
