TGSL meteor channel

[Hyena]

Hi, I am not skilled in electronics so I would ask anyone here... I wonder if there is simple way to modify TGSL to be able in detecting hot rocks.
Channel which reacts on GB change while ignore disc/fe channel? Something like GB set to accept ferrite and reject steel. There are free pins on 4024 so it can make different sound from fe/disc.

Meteors normally have a high iron content. If you only want to dig iron you could add the two tone so ferrous and none ferrous have a different sound.

Only 6% of all meteorites contains iron. 86% meteorites contains chondrites - Triolite (Fes, which is non-conductive) and non-conducting and non-magnetic materials.


EDIT: I live in central Europe, if I turn on Fe channel, I will find 100 nails on 1 square meter So I would like to look for materials with high magnetic permeability coupled with low electrical conductivity.

I doubt you can detect a stony meteor. That's why most are found in a desert or on ice. A rock stands out different to the surroundings. After all is a normal rock very similar to all the others in the ground. Iron or stony-iron would mean digging all iron its the only way.
