LOL now I feel a bit better knowing that I'm not the only one sniffing silicone.

I will have to find the schematic,  got it on one of the computers but I seem to remember that it was a 2n4148, will get back to you on this one.

Hi Brent one

All diodes are 1n4148. I may even decide to rewrite the software for it some day.  Tell me are you busy building it?

Yes the trimmer pots are there so that you can use just about any small coil.  Remember to wind it on a bit of ferrite rod from an old radio. I will see if I can find how many turns I had on mine. One thing that I would suggest though is getting 2m of thin coaxial cable,  the one that I used was MIL-C-17F-RG   174  U Adler Kabel it's 3mm in diameter and very flexible,  attach your coil to it and the box to your belt, now if you need you can use the probe to find small nuggets under rocks in the water just keep the box dry. Just a thought,  you could attaches the box to a hard hat or on a shoulder pad. Please post some photos of it when you're done.

Here are some photos of the coil.  You will notice that I used a piece of PVC electrical conduit, placed the coil in the center then filled in up with candle wax, I originally did this so that I could reuse the ferrite rod should it be a fail but then it worked great and ended up staying like that.

I did not find the info that I had some where about the coil but if you have 120 turns you should be OK. By the way that's a nice diameter for a ferrite rod, should work great.
