I remember a post about a large coil called "Long Tom". I have recently made a boat towed mag using the Fluxgate Mag/Gradiometer and of course it only detects ferrous objects. I am interested in making one or more boat towed metal detectors to pick up non-ferrous and ferrous. I would like to make something similar to the JWFishers Pulse 12 with the 24"x36" search coil.
I have a known wreck site and would like to search and detect gold and silver coins and relics at depth. Maybe even make a sled.
If anyone has any schematics or ideas on how to get started, lets see what we can come up with. I would like to know how to make the coil as well as any schematics on the Pulse Induction control box.
Thanks,
Robert
