Predominately i use 80sens,2+ or 3 tones of late and 4 disc,have been using the 3 tones on some of my old roman/saxon sites,as our targets are both high and low conductivity ones and of course the dreaded iron as well,it seems logic to try and use 3 tones and it also have been using my 5'' coil especially on the trashy conditions sites and its become one of my favourite combinations at the moment.For every day use then the Deus is the weapon of choice,for trashy sites the T2 with the small coil is the best combination i find,and for really deep pasture site when hunting for the deep artifacts then subject to the ground conditions either the Nexus MP or TDI Pro with large coil on is the preferred machine.
