Beings the Equinox Multi can generate around 60 Khtz freq and the Anfibio multi only 20 Khtz, I wonder if it is possible. The Nox has been shown to pick out gold chains with VDI's as low as 1 or 2. I just think the Anfibio would struggle, but I like the fact that it has a larger VDI scale. Many other features I admire about the Anfibio as well. The chain finder might be a deal breaker though. Anyone tested the 2 on gold chains not bunched up?
