Complete Hammerhead details are here -> http://www.geotech1.com/cgi-bin/page...head/index.dat
This is a PI detector. In other words, no discrimination

Proscan - you already have the details for this one.

Minelab is an Australian metal detecting company that makes many types of detector. You will not be able to build one of their detectors yourself.

The details for Deltapulse are scattered around on this site. If you are having trouble understanding Proscan, then you can forget this one.

If by Spectra you mean the Whites Spectra V3 ... you have no chance of making a clone.

The term TwoBox refers to a specific type of detector. For example, see here -> http://www.geotech1.com/cgi-bin/page...obox/index.dat

First you need to decide where you intend to treasure hunt, and what you are searching for. Do you need to have discrimination? If the answer is "yes", you should remove all the PI designs from your list. If you intend to search for large deeply buried targets, then you could try building a two-box. For coin shooting, go for a VLF design.

Nor to buy too. Except if he is not real poor man?

Maybe ... but poorman has already said that he is not a professional electronics engineer, so attempting to build a PI with an Atmel Mega-8 microcontroller will be beyond his capabilities.

First yes i need the MD for gold hunting beacuse there is gold fever now day and md is very expensive.......secndly i have misunderstnding about PI MD i thought i had discremination (is discremination mean that the device can setup to the desire metal that you wont to hunt or not) ........thirdly ,yes my electronic skill is only bad concerning with drawing schametics by softwires like eagle and diptrace so i cannot turn it to pcb but if i had ready-made pcb i can print it and make real pcb.

Please see my reply in the other thread. The TGSL design has a 14kHz transmit frequency, and is therefore more sensitive to gold, but it will ignore ferrous (iron) targets.
