Hi All, I am just about to purchase my first serious detector and would really appreciate an unbiased view as to which one I should spend my hard earned cash on, I have narrowed it down to either the DFX or the Quattro, I've read numerous reviews and every body praises both machines, I like the switch on and go simplicity of the Quattro but at the same time don't mind a challenge with all of the capabilities of the DFX, I will be detecting both Beach and parks etc so it needs to be good in both areas, It really comes down to which machine can really go the deepest and find the good stuff. Any advice to make this decision any easier would be greatly appreciated. Cheers
