I think this question is more common than realized. It took a lot of trying for me to find these answers, so I'm just going to make a new thread with them.
I talked to virtue and they informed me that I can use Ion eyes with the sp1/vibe. I just need that milled breech from GOG ($30). So, I have eyes on the way.. am ordering the breech this week and will post my findings.
To turn on the eyes on the vibe/sp1 virtue board you go to programming mode, go to select eye mode (flashing yellow) and hit the trigger once. This is listed as an eye type selection (breakbeam or reflective) in the manual, but actually for the vibe/sp1 it's 1 for on and 2 for off. I'm not sure why they didn't print that but there it is.
Hope this can help someone!
