GB_Amateur Posted February 17, 2018 Share Posted February 17, 2018 An acquaintance has asked if I'd help him find some shotguns he buried several years ago. They are wrapped in oilcloths, sealed in PVC pipes (~3 in = 7.5 cm diameter) and buried about 20 inches (half meter) deep according to him. He says he can show me the approximate location within about 10 m. If all this is accurate it seems like an easy task.... Then again, he also said someone in his family (without him being present) tried to find them with a detector and couldn't. That could be due to a lot of reasons as I'm sure you are already thinking, but my concern is that they may be buried more deeply than he remembers. Which of the following would be your first choice? 1) TDI/SPP with 12 in round mono and 16 V battery pack. 2) X-Terra 705 w/15 in Coiltek 3kHz. 3) Gold Bug Pro (19 kHz) w/15 in Nel Attack. 4) F75 black (13 kHz) w/11x7 in^2 coil operating in cache process. Assuming he has the time and patience I'm going to have all four with me to do a comparison, but I'd like to start with the one that gives me the best chance. Your advice is appreciated.

fredmason Posted February 17, 2018 Share Posted February 17, 2018 use the biggest coil which would be the 705 and 15 inch coil...almost any detector should find iron at that depth...unless they are stainless steel... You did not ask but I would do a grid of 2 feet apart and the at right angles two feet...also people often mis-remember so do a little extra.... fred 1 Link to comment Share on other sites More sharing options...
Steve Herschbach Posted February 18, 2018 Share Posted February 18, 2018 Tough call. Can’t argue with Fred at all on that one. The alternative might be the TDI simply because PI detectors love ferrous targets 1 1 Link to comment Share on other sites More sharing options...
