Unfortunately for me, Mexican pesos have moved to a stainless steel body as for cents and the 1,2 and 5 peso coins are bimetalic which the outer ring is stainless steel, I hunt at the beach only and the 3030 can detect iron within iron lol, I still dig some nails and ferrous items due to the nature of the pesos but 85% of the time I dig a target I know It'll be a coin, brass alloy cents and the big $10 peso coin are easy to detect, they are just screamers for the detector. I know its not your case or interest for the use you may give, but just showing a feature the 3030 can accomplish. I find Gr/Co setting more useful than Fe/Co, though Fe/Co shows both VDI while swinging, Gr/Co I feel it focuses more on the unmasked part of your screen profile, though if you PinPoint you will see how many targets are below your coil, then again thats just my personal opinion, I'm no 3030 expert but ive dug over 2k coins at a trashy beach with it, more than half being stainless coins. Yes there are faster response detectors out there, Deus might be a good example, but I havent tried it and there is no reason for me to try one at the beach since its not a beach performer. Sry I cant help with the video you are asking! GL & HH
