I have had the Deus for two years nearly ,, and its brilliant apart from the obvious attractions like being ,,wireless , and easy portable, physical lightness , there is nothing out there to touch it ,If you get the chance to try one you will see why ,, but it aint a magic wand ,, what it is, and this will save you a lot of confusion .is a detector with four switchable frequencies , they are separate and tuned individually , micro tuned circuits, when you change frequency it automaticaly takes you to center of the frequency segment, you can adjust it + or - a few KCs the range is 4/8/12/18 khz ,it may be useful if some one is using the same frequency near you with a Deus so that you can off set it and not interfere .
The factory setting are for you to just switch and go ,and have been set up by XP, you can tweak them individually to suit, every so often XP bring out updates which you down load straight to your controller , very easy to do , the latest one was the V3/2 which gives you a gold field setting which is basically all metal mode , which will give you readings on your VDI which correspond to target values in other in other discriminatory programs , if that makes sense,, very useful on wet salt sand and other highly mineralised ground , reacivity is like a machine gun its fast , incidentally it does have a wet beach mode , but your better off in Gold Field/all metal IMO,
It is a single frequency machine when being used ,(although you have the choice of 4 ) and single frequency machines on the beach are a compromise so I wont be getting rid of my Sovereign Gt any time soon having said that you can make the Deus work on the beach its fine on dry sand , and in all metal Gold/Field it will go deep on the wet sand , but unless you buy the Wave guide Antenna (that's what they call it) once the coil is submerged a couple of inches it losses the radio link .
There are settings and programs out there ,, Rogers Relics UK forum has a DVD compiled by Roger who is an Xp whizz Kid I think its about £16.00 , I dont think its ultra necessary , theres also a Deus Owners Forum and one State side I believe , good luck with your Deus you wont be disappointed,, if I can help on any thing else let me know..................
