A interesting thread from the opening poster but also some slightly unusual comments as well!!
What i mean by this is that 4 machines are mentioned,all of them in theory are 'beep and dig' machines,the only difference is that 2 have screens,you dont have to use a screen you can just use any machine as a beep and dig one,i also use a selection of machines with or without screen,but 'always' only go by 'audio' on all of them and never use a screen,so why then buy a machine with a screen then ?? for setting up purposes they are helpful ie i use a Deus which of course comes with or without a screen depending on which option your budget can buy,but for the fine tuning of the detector one needs the screen/controller,but once you have the settings dialled in and saved.Then the screen is never used as for the most part the controller is in my pocket or even in my truck.So basically every machine can be seen and used as a beep and dig setup,you dont have too use or look at the screen.
I totally agree that in theory 'no' one machine or machine/coil combination this maybe one with or without a screen can do it all,as mentioned one it can be advantageous if one has a few say coils or machines if possible for site specific use say like wet beach work or trashy site,as some machines excel in some machines better than others.
This is the statement,wording or call it what one likes and i find very confusing is this,prehaps i am missing the point.
Big difference and the Fun of the B & D boys is, you might not come home with gold/silver but you usually dig something that's interesting or a little out of the ordinary. More so than the Vdi boys.
A metal detector with or without a screen still has the same chance of finding gold or silver in what ever format ie gold nuggets or coinage or jewellery or what ever,you just have too walk over it with your coil to find it,a detector is not selective just because it has a screen or not,in my mind all finds are 'interesting',once again a machine with or without a screen is not selective in finding 'interesting or a little out of the ordinary',just because a machine does not have a screen it wont find anything different than a machine which does a screen,after all they all all 'metal detectors'.
I 'do' agree that a machine with less controls can be more of a pleasure sometimes to use,just by the simplicity of switching on and go,but also a Deus can be a switch on and go,i can from switch on and go detecting with this machine in the same duration as it takes to switch on say a Tesoro or what ever machine and can be out detecting and enjoying my self using the machine exactly the same as any other beep and dig machine.Have only used the Deus as a example,but as i see it,one does not have too use a screen and exactly the same way as a 'traditional beep and dig machine' without a screen can also still find 'gold and silver'
Of course these are only my thoughts and opinions.
