Sure did. Also if you look on the Geotech forums myself and others have posted heaps of extra info on the MPP. If you need any help with it just drop me a message.

Surf PI 1.2 from silver dog build

Help Support Prospecting Australia:
Have just finished building a Surf PI. Only spent a couple hours on the beach so far, seems to work quite well found tent peg, nail, $2 coin and a bit of ali can. Goes off on basalt type rocks also. Mounted on a forearm crutch, housed in a piece of 50mm pipe with 3 li-ion batteries. Coil was wound from cheap hookup wire from jaycar on cardboard, housed in epoxy coated corrugated carboard. Got all my info from the Geotech site. Will try and post photos shortly.
Should be able to add photos after this post
Cheers

Having trouble with images.
Maybe I'll have another wine and try again later

He,he' looks good have you done much in the line of tests or detecting with it?
Looking very good.
I made a few of the basket weave coils like you have there. If you get some Litz wire (avail on eBay) you may find it works a little better. Although a fast coil isn't necessary for beach hunting, it will certainly work more efficiently.

Thanks Guys
@ Zuke_Lynzy Haven't had a chance to do any serious depth testing yet but was happy with a few quick tests I did on the day, really need to look a bit more closely at the damping resistor, but it is sensitive to gold.
@ SteelPat Have made a coil from litz wire (bb sailor fast coil) which I am seriously considering dismantling, reusing the wire and trying what you suggest, but that won't happen for a while.

Looking at the coil winding, it just put me off of building a PI.
LOL
That is dedication !
Good work sir.
