I never trust a screen on making a dig decision,as you have mentioned they get 'totally' unreliable the deeper you go,with me it audio all the way as that is very reliable,the only time i basically use a screen of course that is if a detector that i am using at the time has a screen,then its mainly used for setting the machine up and nothing else.
When using my Deus the 'expensive' controller is zipped up in a pocket and i use the machine solely as a audio machine,many times the screen can show no No's but will always give a reliable feint dig or no dig signal.
I Agree with Mega, machines like the CTX can give you multiple tones and even more ID numbers, And where most folks say hunt by Tones, yet those people claim and want the machine to ID things beyond the reach of the machine, Where the Tone is used instead your ears become the best judge, Isn't the thrill and the whole point of detecting about the moment you see the Item for the first time, My machine can see something at 17 inches but it will tell you it is there at 22 inches, Most machines will give you an Idea what an Item is 95% of the time, People seem to want detectors to do it all, Regardless of Brand in a Light Hearted way Detecting is about Treasure, A childhood Dream or just getting out there with Great like minded people.
But people keep wanting more and they forget Metal Detecting 101, whats next on their list ? A machine that tells you which way to go even before you get out of Bed, The VLF market reached it's peak 16 to 17 years ago and the only advancements we have seen comes in the form of the XP Deus that through it's modular design and Ultra light weight and recovery speed has become the benchmark between weight and power and nearly all others fall short in that department.
The Simple way to get the ID numbers to be more accurate is either boot scrape the ground where possible or Dig, because there are too many variables when it comes to detecting, and the Detector companies move very slowly, Companies like Garrett and Tesoro have sat quiet for a long time now and the rest have been feeding the market in drips and drabs for years, and if people are waiting for a Silver Bullet in the Detecting world then they are going to be waiting a long time. the VLF machines that you all own are as good as it gets,
Machines like the F-75, T-2, the CTX and the V3i and the MXT A/P and most of all the XP Deus are the best of the best, The few offerings from the EU have some good features but they lack the memory upon power down and they have been having reliability issues lately, And some of these six machines are the Only tried and tested models that offer anything serious to the end user.
