hiya i dont have a musky, but was thinkin of trying one,,are they as good as the sov,g,t,?? i do however own a cibola,,i have added a 10 turn precision g,bal to it and a 12 x 10 d.d.coil,,,it is totally awesome for depth,, about as deep as physics allow ,,but the iron rejection and quick recovery means you can put a 6 inch large flat iron nail 1 cm away from a small silver coin and it will pick it up after discing the iron,,the air tests i did shows how hot this machine is ,,it loves tiny silver and especially gold,, like a 13mm silver arabic coin at 10.5 inches,,,,,and a very thin george 111 half spade gold coin at 13 inches,,this is in standard threshold, just audible,,,and 13 inches an the silver and 16 inches on the gold with supertune???? awesome,,it also works to huge depth on salt wet with the dd coil,,tried a 1 cent penny around 18 mm clad coin in a foot of sloppy salt wet sand and it found it no problem,,,tell ya,,people just overlook these machines because they are small and light and because of this they cant be as good,,but the vachero and cibola are tejons in frogs clothing,, they are the very latest technology and just can not be beaten,,,they just find stuff the others dont??,BUY ONE,,see for yourself,,,,,rgds comcat
