Depth what is it with this depth thing , there is not one manufacturer who will or can tell you how deep there machines will detect metal objects in the ground, they may indicate or surmise , there are just so many variables I would think an average mid range priced machine would on a wet day detect a trash can lid at two feet, ,ten inches for a small coin is good, most of my finds are mostly down about six inches , but I do pick up coins deeper depends on ground conditions , how often do you get a good signal then dig a good size sod out, it lands brown side up then you run your machine over the hole and get no signal , you then pass the detector over the brown side of the sod /turf still no signal , you then turn the sod green side up pass the detector over it ,, bingo there's the signal it was only a couple inches in to the turf ,, strange ain't it .
The deus is no different, but I have to say its a blinding machine , it does have great advantages just its sheer portability lightness and its wireless, is a big big plus ,you choose your operating frequency , which will give you in theory greater depth at the low frequency , and up at 17 1/2 will pick up all those small coins very fine gold chains , you can alter the reactance you can even up the transmit power , which will work well on un contaminated non minaralised ground which is quite rare but the facility is there , as for water proof yes it is ,and it has a dry beach setting and a wet beach setting which really work ,but because the coil sends the signal to either the control box or the head phones , once the coil is under two inches of water your stumped,,I don't know how they are going to get over that one.
I would say that for general hobby type detecting on land or on the beach ( not under water) the Deus is were a lot of metal detector manufacturers would like to be , the old black box detectors are out the window and the likes of Minelab Whites Garretts you name them will be playing catch up for a long time, tonight I got a call via another forum that a lady in my area had lost a Diamond white gold ring in her front yard ,, turns out she had had a tiff with her old man and lobbed is it out the front door ,so as the gentleman I am, I popped over with in twenty minutes I found it , her smile was worth a million pounds .
I have gone through the full Monty of metal detectors even some exotic ones like the Nexus Explorers Soveriegn 705 it goes on ,the Deus is a lot of money ,well it is for me , I ain't gonna bull Sh## you and say it reaches great depths , but I am finding things that the Explorer and the Sov Gt would never find in a month of Sundays small gold chains very small gold earrings , I just wish the Deus had been on the market years ago ,, its the way go get one ..
