Hi Grendel, that is a really cool idea, I'm very interested to know how it works out!

I still have a bow but it has been a really long time since I have used it...

Looking over your sight, one thing I'm not sure about is having a pressure switch for on/off? Just thinking about if you like to have a loose style grip with the bottom fingers.. Something else being in there might not be so comfortable?

What about maybe just an on/off toggle switch slightly above the grip?

EDIT: Ooops sorry I didn't read it all properly, I see now that you have more to it than just a rangefinder so what I was thinking was a pressure grip is actually those 3 laser switches, sorry!
