what a difference ,had 2 100k knobs put on to my sidewinder,one for the threshold,and one for the ground balance.
easy to do i watched it being done, all he did was unsolder the two trimpots on the board, then soldered 3 wires to each one where the trimpot came off, then he drilled holes for the new knobs in the faceplate,then fitted them on,G-B above the sensitivity knob,and T-H above the discrimination knob.soldered the other end of the wires from where the trimpots were, to the new knobs.and bingo external threshold knob,and external ground balance knob.
now this detector can be used in the hottest,mineralised ground,ie our goldfields here in aus ect.salt beach to on max sens.it makes a big difference on depth in my test plot,as now an exact ground balance can be achieved very easily.also another plus is i can now easily up the threshold audio knob,to max while in discrimination mode,if i wish to. which triples the volume of deep targets, making them so much easier to hear.
i am extremly pleased with the results to say the least. COST FOR TWO KNOBS 100K WAS $4 FROM RADIO SHACK, TANDYS.STORES.
i would be more than happy to have done the mod myself,except i didant have a fine enuff soldering outfit, so it may pay to have it done by a technician wouldant cost much. regards ken
