I’m thinking of adding an Anfibio to my collection of detectors. I have 40 some years of detecting experience under my belt so not a newbie. I currently use CTX and a Deus and for years have only used multi tones and rarely use the VDI. most of the stuff I’ve read on the Anfibio says they are using 4 or 5 tones and I’m wondering what the reasoning is. A lot of videos show this also. There are no local dealers around here for me to try the machine and just don’t want to buy one and then not be happy with it, done that to many times
