Ultimate detector

[Anonymous]

I have been reading your forum for quite some time now and have learn a lot. Can youu outine everything you would do to produce the ultimate coil and ring detector if cost were no object? For example: 1. DD coil for receive with seperate transmit coil. 100uH on xmit-1mH on receive 2. Fet isolated from coil with diode. 3. Seperate tarnsmit and receive wiring. 4. 2 Dual gate integrators with sample and hold outputs. 5. All circuits operated synchronously.
etc- you get the idea. Thanks for your comments.

Since we all have day dreamed about this, how about checking out current technology that exists today to craft an "ultimate" detector if money were no object. For example, a gas utility in Oklahoma City has used a trailer mounted rig comprising several integrated, PC based systems that will give the technician a high resolution scan of pavement subgrades, showing all metal objects including pipe lines, down to individual nails. I've been told this scan goes to a depth of six or seven feet. Cost est. is $250k. Major airports utilize scanners that can freeze frame, slice, rotate, enlarge and colorize various component parts of objects viewed in luggage. Combine this with magnetic resonance imaging, ground penetrating radar, other current medical scanning technologies, and a PC driven liquid crystal display screen to show off your target in real time, three dimensional views, you will have a killer ring detector. Put all this in a normal sized detector box and meter sized display, and you've got one hot machine. I'm patiently waiting. Any comments?---Rick
