I have a Halo B and time ago it started flashing red and green, so the guys at the field told me it was either batteries or dirty eyes, so I changed the batteries, but it kept doing the same. I opened it up cleaned the eyes and nothing, it spins a couple of times and afterwards it stops and starts flashing. I finally bought a new eye kit for it, but with the new, the old, or no eyes connected at all it does the same! Does somebody know what's happening? :? Thanks.
