I had a Kilo 3000BDX bino/rf . The RF function was very strong, at least as good as the Geovid I had. The big problem I had was that the RF did not align properly with the reticle. The beam was actually at 6:30 outside the aiming reticle. This is obviously a big problem if you are trying to range game/target that is just over the top of brush lines. It also had wandering diopters that shifted around alot without me touching them. I told Sig about the problem and they replied with "we feel the unit is within spec" answer. I sent them back to where I bought them.
I do still have a 2200 BDX RF unit and it has been great. The beam and reticle actually align in this one so it is a keeper. I have no experience with the newest Leica RF's for comparison, but for me to be confident in what I'm doing afield, the beam/reticle alignment is crucial.
