Your DREAM MACHINE, or what would you like to see in future MD's?

I've taken a layman's view in studying various aspects of the metal detectors on the market and I have my own idea of what I would like to see in future metal detectors, but I was wondering if anyone else had some ideas on the future direction of metal detectors and what features they, (you), would like to see in future models?

Personally, I would like to see detectors with dual receivers that would allow for canceling out iron, (bottle caps, nails, etc), on one side and pull tabs on the other. I think this would allow the electronics to analyze the output more accurately. Current MD's seem to be stuck in "mono" mode. And a stereo audio output from dual receivers would give a better idea of what was found. This might mean having to use a single Tx, (transmit) coil with dual Rx, (receiver), coils. This would nearly double the circuitry involved, but I really think the result would be worthwhile.

A second idea I had that I've mentioned in another post elsewhere is that, I would like to see an MD with multiple Rx coils, similar to those used in microwave arrays, as I believe this would add directionality to a received signal along with better pinpointing ability.

I'm not an electronics guru, but I look at things from the perspective of the end user and as a layman, I seem to come up with what I think are good ideas. I may even find time over this next winter, (I shudder at saying that word), to experiment with this myself, but I know that I'm not very well equipped to handle the delicate electronics involved in such a project and might, (very likely will), end up toasting some electronics in the process.

Anyone else out there with ideas on this?

I would say that the GEM-3 with the 20 cm head is the closest thing to a dream metal detector. It is an actual geophysical metal detector that is designed to be used for landmine detection. That means that it logs the data as well as position information so that it can be processed later. It is out of the price range of most hobbyists at $20K, but the price could come down to the ~$3K range. It is a frequency domain instrument that can operate over a wide frequency range (30 Hz to 50 kHz). Typically five to ten frequencies are used which allows for the measurement of the target response spectrum. In air it can identify targets by type (penny, nickle, dime, quarter, pull tab, anti-personnel mine) based on a library of target signatures. The features that could be added are the ability to add soil responses to the target responses and also adding two orthogonal receiver coils (which they have done on the larger 96 cm coil for UXO detection).

That GEM-3 sounds like a heck of a machine 99thpercentile. After I was offline I was thinking I should have mentioned about the other machines out there that have multi-frequencies. It seems like that would be a natural preference, but maybe just having more control over what frequency range the user wishes to use, would be a good thing to have.

Once I have a good reliable machine for myself, I hope to hunt up some other older machines to experiment on during those frigid winter months when the ground is frozen. I only have the analog meter on my Compass Magnum 420 and considering its condition, I've thought of patching in a digital multimeter with LCD display. I picked it up at the flea market with a dead battery and the price of a replacement is more than the $2 I paid for it, so I thought I'd power it off the MD's battery pack. But for now, I need the Magnum for a planned hunt coming up as soon as demands on my time allow and the weather permits.

I want a machine that will dig up my finds too. Especially in this awfully hard dry ground we have where I'm at.

Just kidding, but I had to be the smart one to post this

Where can you read info on this unit...I did a search, but found nothing...thanks, Tom

Thank you for the link...BTW, good idea trying to patch in the multi meter, keep us posted as to what happens.....

What about a screen that would give you a 3 dimensional view of your find and tell your precisely how deep it is. Does that exist now??
