Fletch, the relic mode is somewhat like two tone ferrous on an Etrac. I hunt in a modified all metal mode with conductive sounds. I seem to get many 39-40 high tones that repeat from different angles. After digging many of these deep signals, I found them to be rusty nails and such. I started checking them in the stock all metal mode which has ferrous sounds and they grunted like iron. If they high toned and did not grunt, I dug them and most proved to be deeper coins. I really like the Safari and if someone does not want to mess with a lot of settings, the Safari is a very simple FBS version. I have found it to have almost identical performance to a Ex 11 or SE Pro. I do miss having a gain adjustment, but with twenty hours or so in the field, I will say it is a very simple to use detector. I had one of the first Quattros and I did not like it's recovery speed in trashy areas. The Safari is a way faster and that translates into a better all around detector.
