hey i have a question for ya. i was reading in 1 of your post that u said that a windy day can affect a metal detectors performance. now what id like 2 know is how is that possible? ive never heard of that. not sayin that your full of it, id just like 2 know how that works. 2nd i seem 2 b catching on 2 this MD thing w/ my quattro. b4 if u remember i had all kinds of problems w/ it, even thought it was broke. BUT 2 things i did 2 remedy this was 1st i reset the quattro (dont know if that had anything 2 do w/ it or not) 2nd i put on my 5" disk and keep sens at 9. now what this did 4 me i noticed was cut out alot of the junk under the coil, which i knew. ALAS its not so confusing anymore. 6 years ive had this thing and just NOW its workin like it should 4 me. think i mite b on 2 something here. my 11" platypus is 2 big and i get 2 many signals that confuse me and i cant catch on and learn it.so there u have it. c ya
