Anyone know of a good DIY detector?

	I would not personally recommend thinner wire as this will reduce the current taken and therefore the power emmitted, it could easily make your MD far less effective.

This is not true at all. The field is a static electricity field not derived from current but from voltage. The higher the voltage, the bigger the field. You have to stay within the practical limits of a hand held device and the field collapses rapidly. Current is not relevant to the field strength. Yes, you need some current flow or the field will never build but you don't need much.

Now where did I put that wire LOL I really must try this coil out with the thinner wire this could be where my problem was all along.

Generally I don't recommend another forum on a forum, but as many of the members here are also on other forums as well (you really need to be on as many as possible for a good overall picture), I am breaking the rule and I am telling you to also look here as they also have many complete details of some really good metal detectors:-

I am still in the middle of building the IGSL with DIY coils, from an excellent kit from SilverDog.

A slightly simpler version to start with is the TGSL, again a kit is available from SilverDog, and there is a lot of friendly folks to help and support you in whatever you decide to do.......

Recently there has been an addition of an LCD system (VDI) using a PIC for the intelligence, to differentiate between targets, that can be added to various detectors if wished....Program is included.

I personally would recommend as a first a VLF, but generally PIs are even simpler to make (usually only one coil and no nulling), but many PIs have no form of discrimination at all, but do go to a good depth......not all PIs find gold well and may need to be either adjusted or changed (that is from word of mouth, not personal experience!)

I do have full details of a Polish deep PI that I intend to eventually build, probably next year, that uses normal parts and does not require any fantastic electronic knowledge, also I have translated enough of the original documents to allow a good build and  setup....

Look here and if it interests you further, just drop me a line and I will post all the infos that I have for you to download, OK?

The infos include a schematic &  PCB design for Eagle CAD as well as my Polish to English translation giving parts lists and setup infos in English.
