[QUOTE="Ben78, post: 135108, member: 206"] Moneybox, the Surf PI 1.2 is actually the old Whites Surfmaster designed by Carl Moreland. He put the circuit into the public domain via his Geotech website with the aim to have the 'community' work together to produce new designs and better functioning detectors. The result directly was the silverdog kits - which were very professionally designed through the geotech forum. Anyone can produce a circuitboard off the schematic but it may not be a great board due to capacitance in the layout on PCB amongst other things. This is part of the reason the Silverdog kit is so popular. The community also went on and designed the Barracuda and Hammerhead detectors. The later version Hammerhead was Surface mount components. The circuits aren't basic as a means to be easily made they are basic because a non ground balancing PI is a basic affair, essentially Pulse, turn off pulse, wait a little bit, see if the pulse is bigger than expected, do it again. If you read the Hammerhead doc it explains how that circuit works and what all the components do - [url=http://www.geotech1.com/pages/metdet/projects/hammerhead/HHv1p5.pdf]www.geotech1.com/pages/metdet/projects/hammerhead/HHv1p5.pdf[/url] [/QUOTE]
