Well here it is ,
I can only tell you what we saw and I hope NO ONE decides to "flame" me over what I saw. This is something that I think will serve everyone who gets one very well. This is not a new detector, for the moment , but an add on that one can buy for Minelab SD Series or a GP metal detector.
Tonight we, our metal detecting club, saw a demonstration of a device that weighs about 20 grams( about the weight of reading glasses) and it attaches externally to the Minelab SD series or The Minelab GP, coils and their lower shaft.(tried and tested only on these two types of detectors but we think that it was designed mostly for P.I.).
This device comes into it's own when you detect a ferrous object like a tin can at the usual depths. You push the switch mounted to the handle to another position and it will NOT sound out if it is a NON ferrous object. Switch back and if there is still a signal then dig.
Unaffected by common interference from all most obvious sources, like the detector it self and 50Hz devices and it does this is WITHOUT LOSS of depth and tracking.
When a piece of IRON STONE or HOT ROCK was placed near to the coil, it to was clearly detected.
It can be, I seems, a type of reverse enhanced discrimination.
In other words, it will detect in all metal, as usual, but when you are ready you can tell if it is a good target i.e.: better that iron, even on a piece the size of a THIRD of a rusty or a new staple.
It does not discriminate out the ferrous objects but rather it confirms that the object is ferrous so when you push the thumb button switch, for that moment, you get a NULL when it is over a ferrous object. Let the switch go and it is back to all metal detecting. Power consumption is very minimal and the whole idea seems very simple and it VERY effective.
The device is an a rectangle about 1 inch by 4 inches a 1/4 inch thick. This sits in the area in the void that is in the main body of a coil's outer rim and it's shaft mount. It can be "cut" in as most of this area has nothing in it or simply mounted with velcro tabs on the face up of a coil. Getting it closer to the ground is advantageous but not totally necessary.
From this a cable about a 1/4 thick that runs up the search coil shaft and OVER the standard coil cable up to a small box with a (9 volt battery and the circuitry)and then attatched by clips onto the shaft. Another small cable comming out has the push button switch that mounts onto the detector handle for a thumb actvated on/off. That
