congradulations , on your new silver umax, i really like mine i had a m-6 but it was to heavy for me and i dug almost everything whith that, then i got a cibola then a silver umax because i wanted to have an all metal mode and hear is what i have found between the silver and the cibola the cibola,s sesitivity was nice because you could turn it way down , i mean you could get coins at 1---2" deep and it was great or you could turn it up and get the 4" coins or turn it moor and get the 5.5" to 6" coins it was really great that way and the 6x9 coil was absolutly great pinpoints to one sq inch very good but you could get on for the silver to now the silver is good in that it has the all metal wich would pick a chain out easaly but in disc harder and the silver is just a wee bit less depth but that is using the 8" coil the 6x9 maybee the same as the cibola and it really is strong on nickles if i sell the umax i have it will be because of finasial destress i really do like it and i have heard the 10x12 coil gets really good depth so really its a good machine and if you get into moor minearalized ground the all metal mode will cut thru it very well thats why i got the silver if the cibola had a good all metal i never would have sold it and get the 5.75 its very good still foze up hear in minnesota cant wait to get out but i will wait i have no coice may you find a lost cash of gold whith your silver ,, gunnar of bradford minnesota ohh and by the way the sesitivity on the silver is way difrent at its lowest seting i can easaly pick coins out at 3.5 to 4" and max 6" its almost like the compodry cant be turned way down that is to get coins at 2" or so but i can work whith it
