Hi

I am very new to detecting. My girlfriend got a Garret 150 for Xmas and we have been out detecting together and I caught the bug. Got hold of an old Micronta 4003 for next to nothing at an auction in the hope of learning a bit until I can afford a better one. Has anyone got any advice on using this. I have been using it in VLF mode with sensitivity at 2/3 and Discrimination at 0. It seems to be able to pick up metals but at no great depth. I tested it with a silver ring under a pile of leaves and it couldn't detect the ring. Am I doing something wrong? I have read around the net and some people have had some real luck with these detectors.

Hi and welcome,

first off turn the gain up to about 7 minates past and set the ground at 12 oclock and set it to vlf 1 if it starts to make a constant tone press the red button on the handle lower the coil to the ground and if the needle rises then press the red button again and turn up the volume, Just make sure theres no metal in the ground where you do this and it should see down to about 4 to 6 inches on coins if the mineralization is not to bad , anyway give that a go and tweak it to suit your ground, ok.

Good Luck,, AU

Do you have the Instructions for the beast?   Hold down the Button when you tune it and the silly things do quite good on coins and stuff.

The oooold way of ground balancing a detector. Those where the days. If you couldn't tune the detector you couldn't find anything. I recon 80% of today's metal detector users they haven't even hear of manual ground balance.

My kid used one for two years and was keeping up with my finds.  He had different Ideas on where to hunt and did quite well.    You use the Tune Pot to tune. Not the Volume.   Hold down the Red Button,  holding the detector in the air.  Tune it.  Place the Coil 3" from the ground and if it goes louders (Tone) Turn the Tune pot counter clockwise.    Do the opposite if it goes shush.  This is NOT in the Manual.

When my kid up graded I think I gave that one away on a contest here.

Thanks for all the advice. I was led to believe that it wasn't a very good detector but now feel it might be worth persevering with. As far as the comment about tuning is concerned - I know the modern detectors don' make any sound until they find something, but should mine have a slight hum whilst hunting or be silent?

Also. I read an article about setting ground on these and it seemed a bit complicated - all the fine tuning. I presume one way isn't sand and the other soil?

Yes.   Tune it so you can just hear the toon.
