Excellent binos!

I ended up with the GPO range guides after trying several other brands including 2 'alpha' RF binos. The 10x40 range guides have impressive optics, much better than I was expecting. The RF is solid, I use these for 3D archery as well as hunting and they have no problem ranging black targets which is where many RF binos fail. The build quality is excellent, optical performance is excellent with a sharp image across 90-95% of the field. This is way better than some RF bins that cost equal or more. The RF display is sharp and clear under all conditions. Only problem I've noted is ranging in foggy conditions can be spotty, but they work perfect in rain which surprises me.
