First question?When you turn on metal detector only a electric signal gos, out at certain Millie watts and Hz and nothing else?On the return signal is everything and you are really adjusting the software in the box ,so all machine are the same it is just who has better software?You are just adjusting signal to reduce background noise and separate everything?So if you had a ubs port and a flash drive you could copy the signals all day bring it home and if you had the app or software you could plug flash drive in your computer and do same thing as the metal detector .if you had all the major company,s software you could put it through each one.?Not sure if i stated this right, thanks for trying to answer.
