Jaytrav76, I own the monster and nox 800 , the monster with the 10x 6 used in all metal mode will give you the better depth than the 5 inch round in the same mode , you can read the bar graph to decide if you are going to dig or not as it still shows on the graph , if you don,t want to hear every target use discriminate but turn up the gain 2 notches to get back some depth, both coils are really easy to use and pin pointing a target is very easy because of the coil widths , the monster is very light and very easy to use only takes 10 minutes to learn and you will have it sorted, pluss are good on the nuggets too, on large junk targets it will show non ferrous when in either mode but better to be safe than sorry I guess It has auto ground tracking as standard , also 2 settings where it adjusts the gain to suit the ground automatically I don,t use these in hot mineralised ground as I feel they may and only may back off the gain a fraction to much when looking for gold in the gold fields .
You could use this as a dual machine but it won,t have the depth of a nox in sand and top soil parks , Its way more than a entry level machine and far from it .
