JPS Posted January 17, 2023 Share Posted January 17, 2023 hello, is it possible to adapt a detection disk for a minelab gpx on fisher's impulse aq, thank you Link to comment Share on other sites More sharing options...
bklein Posted January 17, 2023 Share Posted January 17, 2023 I will be trying some of mine eventually. I don’t expect any issues. I think I asked about this elsewhere and got an ok to try. 1 Link to comment Share on other sites More sharing options...
Joe Beechnut OBN Posted January 18, 2023 Share Posted January 18, 2023 Carolina, where are you buddy? Maybe he can answer...GPX coil to the AQ.. My question..Are the GPX coils water proof? Submersible? Link to comment Share on other sites More sharing options...
bklein Posted January 19, 2023 Share Posted January 19, 2023 Well, I asked Alexandre and he says it could fry the circuit board to try GPX or TDI coils. I haven’t heard of this before as with a PI there are inherently high voltages involved that the design needs to tolerate. For sure there are several things an experimenter could do to cause damage - like misconnect it, have drastically different winding characteristics, or connect it with power on. I will eventually try my tdi beach hog coil - it works great on my GP Extreme and I hope on the AQ. I don’t have any interest in any of the other GP coils really.

Carolina Posted January 19, 2023 Share Posted January 19, 2023 I have discussed this topic before. Eric installed 7 different coils he had available without any issues. If the resistance is 3 ohms or close it will work. There is nothing special about the stock AQ coil. The issue you will have more than likely is the coax cable. He did determine that a mini coax is needed to prevent detection by the coil. The Belden cable used is critical. The AQ cable is a mini dual cable but only one coax is used. Alexandre had another detector design he was working on “ bi polar “ hence the dual mini coax. 2 Link to comment Share on other sites More sharing options...
bklein Posted January 20, 2023 Share Posted January 20, 2023 That original coil Sorieu connector is strange. I was looking at it to investigate the loose pins but couldn’t figure it out so I left it intact. I am not sure if I will succeed connecting a cable to one for an adapter - might need a special insertion tool etc. Have you tried? Link to comment Share on other sites More sharing options...
