Hi, in my country it is difficult to get a permit for a metal detector so I was thinking of using a pipe & cables locator to find gold. the problem is I can't buy from Ffisher or Whites or any company that also makes metal detectors as it will be recognized and confiscated by customs. but I can buy detectors meant purely for utility like the Amprobe AT-3500. my question is can I align the transmitter and receiver perpendicular on a bare like the gemini 3 or similar devices? I mean to cancel the interference between the receiver and transmitter?

Hi, I think of buying the Quest Scuba Tector Pro (https://www.amazon.com/Quest-Scuba-Tector-Metal-Detector/dp/B08HQYH81T), it is a Pulse Induction detector, i intend to use it on land so i need more depth hence i want to build a 15 inch coil for it, by measuring the inductance of the stock coil and building a 'similar inductance' big coil, will it work? also, does the pulse power also affects the depth, i guess from the small battery and the advertised 14 hour life that it is using less power per pulse, if power maters then will using a 20% lower resistance for the new large coil (thinner wire) help force a bigger current and consequently more power (assuming it is driven by a voltage generator)? note: I know i can find many similar models with big coils but for some reasons am limited to this particular detector and I want it to find gold jars 3 foots in mineralized ground
